How can I make a UITextField move up when the keyboard is present - on starting to edit

Question

With the iOS SDK   I have a UIView with UITextFields that bring up a keyboard  I need it to be able to    Allow scrolling of the contents of the UIScrollView to see the other text fields once the keyboard is brought up Automatically  jump   by scrolling up  or shortening   I know that I need a UIScrollView   I ve tried changing the class of my UIView to a UIScrollView but I m still unable to scroll the textboxes up or down     Do I need both a UIView and a UIScrollView   Does one go inside the other   What needs to be implemented in order to automatically scroll to the active text field   Ideally as much of the setup of the components as possible will be done in Interface Builder  I d like to only write code for what needs it   Note  the UIView  or UIScrollView  that I m working with is brought up by a tabbar  UITabBar   which needs to function as normal     Edit  I am adding the scroll bar just for when the keyboard comes up   Even though it s not needed  I feel like it provides a better interface because then the user can scroll and change textboxes  for example     I ve got it working where I change the frame size of the UIScrollView when the keyboard goes up and down  I m simply using    - void textFieldDidBeginEditing  UITextField   textField          Keyboard becomes visible     scrollView frame   CGRectMake scrollView frame origin x                        scrollView frame origin y   scrollView frame size width  scrollView frame size height - 215   50       resize    - void textFieldDidEndEditing  UITextField   textField        keyboard will hide     scrollView frame   CGRectMake scrollView frame origin x          scrollView frame origin y        scrollView frame size width        scrollView frame size height   215 - 50     resize     However  this doesn t automatically  move up  or center the lower text fields in the visible area  which is what I would really like

its simple -  In TextFieldDidBeginEditing -  self view frame CGRectMake self view frame origin x  self view frame origin y-150  self view frame size width  self view frame size height     In TextFieldShouldEndEditing -  self view frame CGRectMake self view frame origin x  self view frame origin y 150  self view frame size width  self view frame size height

I recently found myself in a similar scenario when working on a messaging app  I created a custom UIView that sticks to the top of the keyboard and does most of what you need automatically MessageComposerView   source  thegameengine org  The idea behind this project was to create something that functioned similar to the iMessage composition view AKA   sticks to top of keyboard and moves to bottom of screen when keyboard dismissed handles changes in text handles rotations  In order to resize reconfigure your UIScrollView you ll want to use the following optional delegate method  -  void messageComposerFrameDidChange  CGRect frame withAnimationDuration  float duration  It will be called whenever the frame is changed  resized  repositioned  rotated  and will also supply the animation duration  You can use this information to resize your UIScrollView s frame and content insets as needed

It can be done easily  amp  automatically if that textfield is in a table s cell  even when the table scrollable   NO     NOTE that  the position and size of the table must be reasonable  e g    if the y position of table is 100 counted from the view s bottom  then the 300 height keyboard will overlap the whole table  if table s height   10  and the textfield in it must be scrolled up 100 when keyboard appears in order to be visible  then that textfield will be out of the table s bound

For Swift Programmers     This will do everything for you  just put these in your view controller class and implement the UITextFieldDelegate to your view controller  amp  set the textField s delegate to self   textField delegate   self    Setting delegate of your UITextField to self   Implement the delegate callback methods   func textFieldDidBeginEditing textField  UITextField        animateViewMoving true  moveValue  100     func textFieldDidEndEditing textField  UITextField        animateViewMoving false  moveValue  100        Lifting the view up func animateViewMoving  up Bool  moveValue  CGFloat       let movementDuration NSTimeInterval   0 3     let movement CGFloat     up   -moveValue   moveValue      UIView beginAnimations   animateView   context  nil      UIView setAnimationBeginsFromCurrentState true      UIView setAnimationDuration movementDuration       self view frame   CGRectOffset self view frame  0   movement      UIView commitAnimations       For Swift 4  4 2  5  Change   self view frame   CGRectOffset self view frame  0   movement    to  self view frame   self view frame offsetBy dx  0  dy  movement    Last note about this implementation  If you push another view controller onto the stack while the keyboard is shown  this will create an error where the view is returned back to its center frame but keyboard offset is not reset  For example  your keyboard is the first responder for nameField  but then you push a button that pushes your Help View Controller onto your stack  To fix the offset error  make sure to call nameField resignFirstResponder   before leaving the view controller  ensuring that the textFieldDidEndEditing delegate method is called as well  I do this in the viewWillDisappear method

I know this is too late but I wanted to share with the future visitors especially my way of doing it  Many good methods were shared but I didn t like how the UI becomes totally bad  There s a simple method which involves two parts -   Add the TextField and  whatever you want it to be floating above the keyboard while editing  to a view so they become children of the view  And then it will be easy to maintain the look and not to affect the UI badly  Use the great tool CGAffineTransform TranslationX  x  TranslationY  y  to move the created view above the keyboard     I know it seems very simple but it is really effective and neat

here is a UITextfield  and other similar fields  category that i made that will make the textfield avoid the keyboard  you should be able to drop this in your view controller as is and it should work  It moves the entire screen up so the current textfield is above the keyboard with animations   import  UIView avoidKeyboard h   import  AppDelegate h    implementation UIView  avoidKeyboard   -  void  becomeFirstResponder    if self isFirstResponder      return    super becomeFirstResponder    if   self isKindOfClass  UISearchBar class           self isKindOfClass  UITextField class           self isKindOfClass  UITextView class          AppDelegate  appDelegate       UIApplication sharedApplication  delegate       CGRect screenBounds           appDelegate window frame       CGFloat keyboardHeight      CGFloat keyboardY      CGFloat viewsLowestY      CGPoint origin                 self superview convertPoint self frame origin toView appDelegate window     get this views origin in terms of the main screens bounds      if UIInterfaceOrientationIsPortrait   UIApplication sharedApplication  statusBarOrientation       the window frame doesnt take its orientation into account so if its sideways we must use the x value of the origin instead of the y         keyboardHeight            216          keyboardY                 screenBounds size height  - keyboardHeight    find the keyboards y coord relative to how much the main window has moved up         viewsLowestY              origin y   self frame size height    find the lowest point of this view           else           keyboardHeight            162          keyboardY                 screenBounds size width  - keyboardHeight          viewsLowestY              origin x   self frame size height             CGFloat difference            viewsLowestY - keyboardY   20    find if this view overlaps with the keyboard with some padding      if  difference  gt  0     move screen up if there is an overlap           UIView animateWithDuration 0 3 delay 0 0 options UIViewAnimationOptionBeginFromCurrentState animations                 CGRect frame   appDelegate window frame               if UIInterfaceOrientationIsPortrait   UIApplication sharedApplication  statusBarOrientation                     frame origin y -  difference                            else                   frame origin x -  difference                            appDelegate window frame   frame                    completion nil                look at appDelegate to see when the keyboard is hidden   end   In your appDelegate add this function    NSNotificationCenter defaultCenter  addObserver self selector  selector keyboardHides   name UIKeyboardWillHideNotification object nil     add in didFinishLaunchingWithOptions       -  void keyboardHides  NSNotification   notification        UIView animateWithDuration 0 3 animations             window setFrame  CGRectMake 0  0  window frame size width  window frame size height          completion nil

You can use this simple Git repository  https   github com hackiftekhar IQKeyboardManager  This is a library that manages all the moving of fields automatically   According to their readme  the integration is super easy      without needing you to enter any code and no additional setup required  To use IQKeyboardManager you simply need to add source files to your project   Although this is very good control  in some cases it causes conflict  like in the view controllers with scroll view  It sometimes changes the content size  Still  you can go for it  and try it as per your requirement maybe you could do what I missed

This document details a solution to this problem  Look at the source code under  Moving Content That Is Located Under the Keyboard   It s pretty straightforward   EDIT  Noticed there s a wee glitch in the example  You will probably want to listen for UIKeyboardWillHideNotification instead of UIKeyboardDidHideNotification  Otherwise the scroll view behind of the keyboard will be clipped for the duration of the keyboard closing animation

I was also having a lot of issue with a UIScrollView composing of multiple UITextFields  of which  one or more of them would get obscured by the keyboard when they are being edited     Here are some things to consider if your UIScrollView is not properly scrolling     1  Ensure that your contentSize is greater than the UIScrollView frame size   The way to understand UIScrollViews is that the UIScrollView is like a viewing window on the content defined in the contentSize   So when in order for the UIScrollview to scroll anywhere  the contentSize must be greater than the UIScrollView   Else  there is no scrolling required as everything defined in the contentSize is already visible   BTW  default contentSize   CGSizeZero   2  Now that you understand that the UIScrollView is really a window into your  content   the way to ensure that the keyboard is not obscuring your UIScrollView s viewing  window  would be to resize the UIScrollView so that when the keyboard is present  you have the UIScrollView window sized to just the original UIScrollView frame size height minus the height of the keyboard   This will ensure that your window is only that small viewable area   3  Here s the catch   When I first implemented this I figured I would have to get the CGRect of the edited textfield and call UIScrollView s scrollRecToVisible method   I implemented the UITextFieldDelegate method textFieldDidBeginEditing with the call to the scrollRecToVisible method   This actually worked with a strange side effect that the scrolling would snap the UITextField into position   For the longest time I couldn t figure out what it was   Then I commented out the textFieldDidBeginEditing Delegate method and it all work          As it turned out  I believe the UIScrollView actually implicitly brings the currently edited UITextField into the viewable window implicitly   My implementation of the UITextFieldDelegate method and subsequent call to the scrollRecToVisible was redundant and was the cause of the strange side effect   So here are the steps to properly scroll your UITextField in a UIScrollView into place when the keyboard appears      Implement viewDidLoad to do additional setup after loading the view  typically from a nib   -  void viewDidLoad         super viewDidLoad           register for keyboard notifications       NSNotificationCenter defaultCenter  addObserver self                                               selector  selector keyboardWillShow                                                     name UIKeyboardWillShowNotification                                                 object self view window          register for keyboard notifications       NSNotificationCenter defaultCenter  addObserver self                                               selector  selector keyboardWillHide                                                     name UIKeyboardWillHideNotification                                                 object self view window       keyboardIsShown   NO        make contentSize bigger than your scrollSize  you will need to figure out for your own use case      CGSize scrollContentSize   CGSizeMake 320  345       self scrollView contentSize   scrollContentSize     -  void keyboardWillHide  NSNotification   n       NSDictionary  userInfo    n userInfo           get the size of the keyboard     CGSize keyboardSize     userInfo objectForKey UIKeyboardFrameEndUserInfoKey  CGRectValue  size           resize the scrollview     CGRect viewFrame   self scrollView frame         I m also subtracting a constant kTabBarHeight because my UIScrollView was offset by the UITabBar so really only the portion of the keyboard that is leftover pass the UITabBar is obscuring my UIScrollView      viewFrame size height     keyboardSize height - kTabBarHeight         UIView beginAnimations nil context NULL        UIView setAnimationBeginsFromCurrentState YES        self scrollView setFrame viewFrame        UIView commitAnimations        keyboardIsShown   NO     -  void keyboardWillShow  NSNotification   n          This is an ivar I m using to ensure that we do not do the frame size adjustment on the  UIScrollView  if the keyboard is already shown   This can happen if the user  after fixing editing a  UITextField   scrolls the resized  UIScrollView  to another  UITextField  and attempts to edit the next  UITextField    If we were to resize the  UIScrollView  again  it would be disastrous   NOTE  The keyboard notification will fire even when the keyboard is already shown      if  keyboardIsShown            return             NSDictionary  userInfo    n userInfo           get the size of the keyboard     CGSize keyboardSize     userInfo objectForKey UIKeyboardFrameEndUserInfoKey  CGRectValue  size          resize the noteView     CGRect viewFrame   self scrollView frame         I m also subtracting a constant kTabBarHeight because my UIScrollView was offset by the UITabBar so really only the portion of the keyboard that is leftover pass the UITabBar is obscuring my UIScrollView      viewFrame size height -   keyboardSize height - kTabBarHeight         UIView beginAnimations nil context NULL        UIView setAnimationBeginsFromCurrentState YES        self scrollView setFrame viewFrame        UIView commitAnimations       keyboardIsShown   YES       Register for the keyboard notifications at viewDidLoad Unregister for the keyboard nofitications at viewDidUnload Ensure that the contentSize is set and greater than your UIScrollView at viewDidLoad Shrink the UIScrollView when the keyboard is present Revert back the UIScrollView when the keyboard goes away  Use an ivar to detect if the keyboard is already shown on the screen since the keyboard notifications are sent each time a UITextField is tabbed even if the keyboard is already present to avoid shrinking the UIScrollView when it s already shrunk   One thing to note is that the UIKeyboardWillShowNotification will fire even when the keyboard is already on the screen when you tab on another UITextField   I took care of this by using an ivar to avoid resizing the UIScrollView when the keyboard is already on the screen   Inadvertently resizing the UIScrollView when the keyboard is already there would be disastrous   Hope this code saves some of you a lot of headache

One thing to consider is whether you ever want to use a UITextField on its own  I haven   t come across any well-designed iPhone apps that actually use UITextFields outside of UITableViewCells   It will be some extra work  but I recommend you implement all data entry views a table views  Add a UITextView to your UITableViewCells

Note  this answer assumes your textField is in a scrollView   I prefer to deal with this using scrollContentInset and scrollContentOffset instead of messing with the frames of my view   First let s listen for the keyboard notifications     call this from viewWillAppear - void addKeyboardNotifications         NSNotificationCenter defaultCenter  addObserver self                                              selector  selector keyboardWillShow                                                    name UIKeyboardWillShowNotification                                                object nil          NSNotificationCenter defaultCenter  addObserver self                                              selector  selector keyboardWillHide                                                    name UIKeyboardWillHideNotification                                                object nil       call this from viewWillDisappear - void removeKeyboardNotifications        NSNotificationCenter default     Center  removeObserver self name UIKeyboardWillShowNotification object nil         NSNotificationCenter defaultCenter  removeObserver self name UIKeyboardWillHideNotification object nil       Next step is to keep a property that represents the current first responder  UITextfield  UITextVIew that currently has the keyboard    We use the delegate methods to set this property  If you re using another component  you will need something similar   Note that for textfield we set it in didBeginEditing and for textView in shouldBeginEditing  This is because textViewDidBeginEditing gets called after UIKeyboardWillShowNotification for some reason    - BOOL textViewShouldBeginEditing  UITextView    textView      self currentFirstResponder   textView      return YES     - void textFieldDidBeginEditing  UITextField   textField      self currentFirstResponder   textField      Finally  here s  the magic  -  void keyboardWillShow  NSNotification  aNotification      NSDictionary  info    aNotification userInfo       CGRect kbFrame     info objectForKey UIKeyboardFrameEndUserInfoKey  CGRectValue           if currentFirstResponder is overlayed by the keyboard  move it so it bottom ends where the keyboard begins       if self currentFirstResponder              keyboard origin in currentFirstResponderFrame         CGPoint keyboardOrigin    self currentFirstResponder convertPoint kbFrame origin fromView nil            float spaceBetweenFirstResponderAndKeyboard   abs self currentFirstResponder frame size height-keyboardOrigin y              only scroll the scrollview if keyboard overlays the first responder         if spaceBetweenFirstResponderAndKeyboard gt 0                 if i call setContentOffset animate YES it behaves differently  not sure why              UIView animateWithDuration 0 25 animations                     self scrollView setContentOffset CGPointMake 0 self scrollView contentOffset y spaceBetweenFirstResponderAndKeyboard                                           set bottom inset to the keyboard height so you can still scroll the whole content      UIEdgeInsets contentInsets   UIEdgeInsetsMake 0 0  0 0  kbFrame size height  0 0        scrollView contentInset   contentInsets       scrollView scrollIndicatorInsets   contentInsets      -  void keyboardWillHide  NSNotification  aNotification      UIEdgeInsets contentInsets   UIEdgeInsetsZero       scrollView contentInset   contentInsets       scrollView scrollIndicatorInsets   contentInsets

For Universal Solution  Here was my approach for implementing IQKeyboardManager     Step1 - I Added global notifications of UITextField  UITextView  and UIKeyboard in a singleton class  I call it IQKeyboardManager   Step2 - If found UIKeyboardWillShowNotification  UITextFieldTextDidBeginEditingNotification or UITextViewTextDidBeginEditingNotification notifications  I try to get topMostViewController instance from the UIWindow rootViewController hierarchy  In order to properly uncover UITextField UITextView on it  topMostViewController view s frame needs to be adjusted   Step3 - I calculated expected move distance of topMostViewController view with respect to first responded UITextField UITextView   Step4 - I moved topMostViewController view frame up down according to the expected move distance   Step5 - If found UIKeyboardWillHideNotification  UITextFieldTextDidEndEditingNotification or UITextViewTextDidEndEditingNotification notification  I again try to get topMostViewController instance from the UIWindow rootViewController hierarchy   Step6 - I calculated disturbed distance of topMostViewController view which needs to be restored to it s original position   Step7 - I restored topMostViewController view frame down according to the disturbed distance   Step8 - I instantiated singleton IQKeyboardManager class instance on app load  so every UITextField UITextView in the app will adjust automatically according to the expected move distance   That s all IQKeyboardManager do for you with NO LINE OF CODE really   only need to drag and drop related source file to project  IQKeyboardManager also support Device Orientation  Automatic UIToolbar Management  KeybkeyboardDistanceFromTextField and much more than you think

Though this thread has got enough answers  I would like to suggest a much simpler yet generalised way just like apple does by takes keypads s height into consideration which is greatly helpful when we are using custom toolbar on top of keyboard  though apple s approach here has got few issues   Here is my approach  Slightly modified apple s way  -      Called when the UIKeyboardDidShowNotification is sent  -  void keyboardWasShown  NSNotification  aNotification       NSDictionary  info    aNotification userInfo       CGSize kbSize     info objectForKey UIKeyboardFrameBeginUserInfoKey  CGRectValue  size       UIEdgeInsets contentInsets   UIEdgeInsetsMake 0 0  0 0  kbSize height  0 0       self scrollView contentInset   contentInsets      self scrollView scrollIndicatorInsets   contentInsets        Called when the UIKeyboardWillHideNotification is sent -  void keyboardWillBeHidden  NSNotification  aNotification       UIEdgeInsets contentInsets   UIEdgeInsetsZero      self scrollView contentInset   contentInsets      self scrollView scrollIndicatorInsets   contentInsets

I use Swift and auto layout  but can t comment on the previous Swift answer   here s how I do it without a scroll view   I layout my form in IB with vertical constraints between the fields to separate them   I add a vertical constraint from the topmost field to the container view  and create an outlet to that  topSpaceForFormConstraint in the code below    All that s needed is to update this constraint  which I do in an animation block for a nice soft motion   The height check is optional of course  in this case I needed to do it just for the smallest screen size   This can be called using any of the usual textFieldDidBeginEditing or keyboardWillShow methods     func setFormHeight top  CGFloat        let height   UIScreen mainScreen   bounds size height         restore text input fields for iPhone 4 4s     if  height  lt  568            UIView animateWithDuration 0 2  delay  0 0  options  nil  animations                self topSpaceForFormConstraint constant   top             self view layoutIfNeeded                  completion  nil

I ve put together a universal  drop-in UIScrollView  UITableView and even UICollectionView subclass that takes care of moving all text fields within it out of the way of the keyboard   When the keyboard is about to appear  the subclass will find the subview that s about to be edited  and adjust its frame and content offset to make sure that view is visible  with an animation to match the keyboard pop-up  When the keyboard disappears  it restores its prior size   It should work with basically any setup  either a UITableView-based interface  or one consisting of views placed manually   Here  tis  solution for moving text fields out of the way of the keyboard

I think that the best approach is to use protocol-oriented programming if you are using Swift   First of all you must create a KeyboardCapable protocol  that gives to any UIViewController conforming it the ability to register and unregister keyboard observers   import Foundation import UIKit  protocol KeyboardCapable  KeyboardAnimatable       func keyboardWillShow notification  NSNotification      func keyboardWillHide notification  NSNotification     extension KeyboardCapable where Self  UIViewController       func registerKeyboardNotifications             NSNotificationCenter defaultCenter   addObserver self  selector  Selector  keyboardWillShow     name UIKeyboardWillShowNotification  object  nil          NSNotificationCenter defaultCenter   addObserver self  selector  Selector  keyboardWillHide     name UIKeyboardWillHideNotification  object  nil             func unregisterKeyboardNotifications             NSNotificationCenter defaultCenter   removeObserver self  name  UIKeyboardWillShowNotification  object  nil          NSNotificationCenter defaultCenter   removeObserver self  name  UIKeyboardWillHideNotification  object  nil            You ve notice the extraneous KeyboardAnimatable keyword on the above piece of code  It s just the name of the next protocol we need to create   import Foundation import UIKit  protocol KeyboardAnimatable       extension KeyboardAnimatable where Self  UIViewController       func performKeyboardShowFullViewAnimation withKeyboardHeight height  CGFloat  andDuration duration  NSTimeInterval            UIView animateWithDuration duration  animations       - gt  Void in             self view frame   CGRectMake view frame origin x  -height  view bounds width  view bounds height                 completion  nil             func performKeyboardHideFullViewAnimation withDuration duration  NSTimeInterval            UIView animateWithDuration duration  animations       - gt  Void in             self view frame   CGRectMake view frame origin x  0 0  view bounds width  view bounds height                 completion  nil            This KeyboardAnimatable protocol  gives all UIViewController conforming it two methods that will animate the whole view up and down  respectively   Okay so if KeyboardCapable conforms to KeyboardAnimatable  all UIViewController conforming to KeyboardCapable  also conforms to KeyboardAnimatable  That s cool   Let s see a UIViewController conforming KeyboardCapable  and reacting to keyboard events   import Foundation import UIKit  class TransferConfirmViewController  UIViewController  KeyboardCapable         MARK  - LIFE CYCLE            override func viewWillAppear animated  Bool            super viewWillAppear animated           registerKeyboardNotifications              override func viewWillDisappear animated  Bool            super viewWillDisappear animated           unregisterKeyboardNotifications                MARK  - NOTIFICATIONS       MARK  Keyboard     func keyboardWillShow notification  NSNotification            let keyboardHeight    notification userInfo  UIKeyboardFrameEndUserInfoKey  as  NSValue  CGRectValue   height         let animationDuration   notification userInfo  UIKeyboardAnimationDurationUserInfoKey  as  Double         performKeyboardShowFullViewAnimation withKeyboardHeight  keyboardHeight  andDuration  animationDuration             func keyboardWillHide notification  NSNotification            let animationDuration   notification userInfo  UIKeyboardAnimationDurationUserInfoKey  as  Double         performKeyboardHideFullViewAnimation withDuration  animationDuration            Now your UIViewController will respond to keyboard events and will animate in consequence   Note  If you want a custom animation instead of push or pull the view  you must define custom methods on KeyboardAnimatable protocol or perform them on KeyboardCapable functions  It s up to you

Here is my version using autolayout    The idea is just to embed your view containing textfields   text view in an UIScrollView  set a constraint from the bottom to it s superview  make an outlet and update it s constant according to keyboard height using notifications  This is based on Apple example here  and Apple technical note on UIScrollView using AutoLayout here   1  Embed your View V in a UIScrollView S   If you already set your constants and subviews  you can copy paste your view and subviews in the ViewController s view  then embed it using Editor -  embed menu  and finally delete the copied views    2  Set the following constraints     S to top layout guide   0 S to bottom layout guide   0 S leading to superview   0 S trailing to superview   0 V top space to superview   0 V bottom space to superview   0 V trailing space to superview   0 V leading space to superview   0 V equal width to S Latest bottom V subview to superview   20   3  Create an outlet from the latest constraint to your view controller  4  Use the following code     property  weak  nonatomic  IBOutlet NSLayoutConstraint  bottomSpaceToContentView           -  void viewDidLoad        super viewDidLoad          Do any additional setup after loading the view                     NSNotificationCenter defaultCenter  addObserver self                                              selector  selector keyboardWasShown                                                    name UIKeyboardDidShowNotification object nil          NSNotificationCenter defaultCenter  addObserver self                                              selector  selector keyboardWillBeHidden                                                    name UIKeyboardWillHideNotification object nil      -  void didReceiveMemoryWarning        super didReceiveMemoryWarning          Dispose of any resources that can be recreated      pragma mark - Handle keyboard     Called when the UIKeyboardDidShowNotification is sent  -  void keyboardWasShown  NSNotification  aNotification       NSDictionary  info    aNotification userInfo       CGSize kbSize     info objectForKey UIKeyboardFrameBeginUserInfoKey  CGRectValue  size       self bottomSpaceToContentView constant   kBottomMargin   kbSize height       self view layoutIfNeeded         Called when the UIKeyboardWillHideNotification is sent -  void keyboardWillBeHidden  NSNotification  aNotification       self bottomSpaceToContentView constant   kBottomMargin       self view layoutIfNeeded       And tadaaaaa  it works

As per the docs  as of iOS 3 0  the UITableViewController class automatically resizes and repositions its table view when there is in-line editing of text fields  I think it s not sufficient to put the text field inside a UITableViewCell as some have indicated   From the docs      A table view controller supports inline editing of table view rows    if  for example  rows have embedded text fields in editing mode  it   scrolls the row being edited above the virtual keyboard that is   displayed

Please follow these steps  it might be helpful  Put one view then put your textfield on that view and detect the event by delegate when your keyboard is coming up at that time instant animate the view up You can assign some position for that view also  then your view would be going up to that position Do the same thing for animating the view down   Thanks

Add my 5 cent     I always prefer to use tableView for inputTextField or scrollView  In combination with Notifications you can easily mange such behavior   Note  if you use static cells in tableView such behaviour will manage automatically for you       MARK  - Notifications fileprivate func registerNotificaitions         NotificationCenter default addObserver self  selector   selector AddRemoteControlViewController keyboardWillAppear                                                  name  NSNotification Name UIKeyboardWillShow  object  nil      NotificationCenter default addObserver self  selector   selector AddRemoteControlViewController keyboardWillDisappear                                              name  NSNotification Name UIKeyboardWillHide  object  nil     fileprivate func unregisterNotifications         NotificationCenter default removeObserver self      objc fileprivate func keyboardWillAppear   notification  Notification        if let keyboardHeight    notification userInfo  UIKeyboardFrameEndUserInfoKey  as  NSValue   cgRectValue height           view layoutIfNeeded           UIView animate withDuration  0 3  animations                let heightInset   keyboardHeight - self addDeviceButton frame height             self tableView contentInset   UIEdgeInsets top  0  left  0  bottom  heightInset  right  0              self view layoutIfNeeded              completion  nil            objc fileprivate func keyboardWillDisappear         view layoutIfNeeded       UIView animate withDuration  0 3  animations            self tableView contentInset   UIEdgeInsets zero         self view layoutIfNeeded          completion  nil

First of all  I recommend a better design for your page so that there is no need to scroll your view  If you have many text fields  you still don t have to use a ScrollView  it just makes things complicated  You can just add a container UIView on the top of the controller s original view  then put those text fields on that view  When the keyboard shows or disappears  just use an animation to move this container view

I found  DK  to be the solution I started using  However  there is the assumption that the scrollView covers the entire view  That was not the case for me  I only wanted a scrollView in case the keyboard covered the lower textfield on my login screen  So my content view was the same size as my scroll view  which was smaller than the main view   It also didn t account for landscapes  which is where I got into trouble to begin with  After playing around with it for several days  this is my keyboardWasShown  method   -  void keyboardWasShown  NSNotification  aNotification          A lot of the inspiration for this code came from http   stackoverflow com a 4837510 594602     CGFloat height   0      NSDictionary  info    aNotification userInfo        CGRect kbFrameRect     info objectForKey UIKeyboardFrameEndUserInfoKey  CGRectValue       CGRect kbBoundsRect    self view convertRect kbFrameRect fromView nil      Convert frame from window to view coordinates       CGRect scrollRect   scrollView frame      CGRect intersect   CGRectIntersection kbBoundsRect  scrollRect        if   CGRectIsNull intersect                 height   intersect size height          UIEdgeInsets contentInsets   UIEdgeInsetsMake 0 0  0 0  height  0 0           scrollView contentInset   contentInsets          scrollView scrollIndicatorInsets   contentInsets                Figure out what the view rectangle is for the scrollView     CGPoint contentOffset   scrollView contentOffset      CGRect visibleRect   CGRectOffset scrollRect  contentOffset x  contentOffset y         I m not 100  sure if this is needed right  My scrollView was always at the top in testing      visibleRect size height -  height      CGRect activeRect   activeField frame       if   CGRectContainsRect visibleRect  activeRect                  self scrollView scrollRectToVisible activeField frame animated YES             I also had some difficulties getting to to work with auto layout  If I don t have the layouts done correctly  I don t get the scrolling I expected  One thing that made life much easier was to place all of the items that were to be scrolling into a single view  and placed that as the only item in the scroll view  I called that single view the  content view    I think the key part was that the content view had a set width and height  This allowed the scroll view to know exactly how much content it had to deal with  This goes a little backwards from usual layouts  Normally the views are trying to take as much room as possible  With the contents of a scroll view  you are trying to get the view to confine itself as much as possible  The content view allows you to put a stop to that  So I gave mine a height of 248  and used the standard screen width of 320 as my width   The layouts that eventually worked for me were these    Scroll View to super view  Basically I gave constraints to the top  left and right   Horizontal Space - View - Scroll View  0  Vertical Space - View - Scroll View  0  Horizontal Space - Scroll View - View  0   Scroll View height  I set the scroll view with a constant height  I don t know if this was truly necessary  but it got the bounds of the scroll view itself   Height -  248  - Scroll View  The content view to the scroll view  I gave constants to all sides  the top  left  bottom and right   Vertical Space - View - Scroll View  0  Vertical Space - Scroll View - View  0  Horizontal Space - View - Scroll View  0  Horizontal Space - Scroll View - View  0   The dimensions of the content view    Height -  248  - View Width -  320  - View

You need to add scrollview programmatically with specific frame size  You have to add UIScrollViewDelegate in  h file  You have to enable scrollview for that you need to write following in viewDidLoad     scrollview scrollEnabled YES  scrollview delegate self   scrollview frame   CGRectMake x y width height     ---set the content size of the scroll view---    scrollview setContentSize CGSizeMake height width      This way  you can add your x  y  width and height values

It s actually best just to use Apple s implementation  as provided in the docs  However  the code they provide is faulty  Replace the portion found in keyboardWasShown  just below the comments to the following   NSDictionary  info    aNotification userInfo   CGRect keyPadFrame   UIApplication sharedApplication  keyWindow convertRect   info objectForKey UIKeyboardFrameBeginUserInfoKey  CGRectValue  fromView self view   CGSize kbSize  keyPadFrame size  CGRect activeRect  self view convertRect activeField frame fromView activeField superview   CGRect aRect   self view bounds  aRect size height -   kbSize height    CGPoint origin    activeRect origin  origin y -  backScrollView contentOffset y  if   CGRectContainsPoint aRect  origin         CGPoint scrollPoint   CGPointMake 0 0 CGRectGetMaxY activeRect - aRect size height         backScrollView setContentOffset scrollPoint animated YES       The problems with Apple s code are these   1  They always calculate if the point is within the view s frame  but it s a ScrollView  so it may already have scrolled and you need to account for that offset   origin y -  scrollView contentOffset y    2  They shift the contentOffset by the height of the keyboard  but we want the opposite  we want to shift the contentOffset by the height that is visible on the screen  not what isn t    activeField frame origin y- aRect size height

A much  much more elegant solution is to use a UIView subclass  though this isn t always appropriate  and recalculate all your subviews on a parent s frame change  and be smart  only recalculate them if the new frame size has changed  i e  use CGRectEqualToRect to compare the new frame when you override setFrame and BEFORE you call  super setFrame frame      The only catch to this is that the UIViewController you intend to use should probably listen to keyboard events  or  you could do it in the UIView itself  for handy encapsulation    But only the UIKeyboardWillShowNotification and UIKeyboardWillHideNotification   This is just so it will look smooth  if you wait for CG to call it  you will get a moment of choppiness    This has the advantage of building a UIView subclass that does the right thing  anyway   The naive implementation would be to override drawRect   don t   a better one would be to just use layoutSubviews  and then in the UIViewController  or whatnot you can call  view setNeedsLayout  in a SINGLE method that is called for either show or hide    This solution gets away from hardcoding a keyboard offset  which will change if they are not in split  etc  and also means that your view could be a subview of many other views and still respond properly   Don t hardcode something like that unless there is no other solution   The OS gives you enough info  if you ve done things right  that you just need to redraw intelligently  based on your new frame size    This is much cleaner and the way you should do things    There may be an even better approach  though    Cheers

In iOS moving keyboard up and taking back for textfields in app is bit confusing and need to implement few methods for same  also you need to make delegate to textfield and take care of it  Code for it will repeat in every class where the text fields exist   I prefer to use this Github control    IQKeyboard  In which  We do not need to do anything  -- just drag drop control to your project and build  -- It will do everything for your app   Thanks   May be this will be useful

If you want your UIView shift properly and your active textfield should accurately position to user need so that he she can see whatever they are input    For that you must use Scrollview   This suppose to be your UIView hierarchy   ContainerView -  ScrollView -  ContentView -  Your View    If you have made UIView design as per above discuss hierarchy  now in your controller class you need add notifications observer in viewwillappear and remove observer in viewwilldissappear     But this approach needs to add on every controller where ever UIView need to shifts   I have been using   TPKeyboardAvoiding  pod   It is reliable and easily handle shift of UIView for every possible case wether if you are Scrollview   TableView  or CollectionView   You just need to pass class to your  scrolling view     Like below     You can change this class if you are tableview  to  TPKeyboardAvoidingTableView   You can find complete running project Project Link    This robust approach I ve been followed for development   Hope this helps

When UITextField is in a UITableViewCell scrolling should be setup automatically   If it is not it is probably because of incorrect code setup of the tableview   For example when i reloaded my long table with one UITextField at the bottom as follows      - void  viewWillAppear  BOOL animated       self tableview reloadData       then my textfield at the bottom was obscured by the keyboard which appeared when I clicked inside the textfield   To fix this I had to do this -  - void  viewWillAppear  BOOL animated         add the following line to fix issue      super viewWillAppear animated        self tableview reloadData

Shiun said  As it turned out  I believe the UIScrollView actually implicitly brings the currently edited UITextField into the viewable window implicitly    This seems to be true for iOS 3 1 3  but not 3 2  4 0  or 4 1   I had to add an explicit scrollRectToVisible in order to make the UITextField visible on iOS    3 2

It doesn t require a scroll view to be able to move the view frame   You can change the frame of a viewcontroller s view so that the entire view moves up just enough to put the firstresponder text field above the keyboard   When I ran into this problem I created a subclass of UIViewController that does this   It observes for the keyboard will appear notification and finds the first responder subview and  if needed  it animates the main view upward just enough so that the first responder is above the keyboard   When the keyboard hides  it animates the view back where it was   To use this subclass make your custom view controller a subclass of GMKeyboardVC and it inherits this feature  just be sure if you implement viewWillAppear and viewWillDisappear they must call super    The class is on github

A much simpler yet generalised way just like apple does by takes keypads s height into consideration which is greatly helpful when we are using custom toolbar on top of keyboard  though apple s approach here has got few issues   Here is my approach  Slightly modified apple s way  -      UIKeyboardDidShowNotification -  void keyboardWasShown  NSNotification  aNotification       NSDictionary  info    aNotification userInfo       CGSize kbSize     info objectForKey UIKeyboardFrameBeginUserInfoKey  CGRectValue  size       UIEdgeInsets contentInsets   UIEdgeInsetsMake 0 0  0 0  kbSize height  0 0       self scrollView contentInset   contentInsets      self scrollView scrollIndicatorInsets   contentInsets        UIKeyboardWillHideNotification -  void keyboardWillBeHidden  NSNotification  aNotification       UIEdgeInsets contentInsets   UIEdgeInsetsZero      self scrollView contentInset   contentInsets      self scrollView scrollIndicatorInsets   contentInsets

This question has already a lot of answers  some said to use scroll view  some said to use a third lib   But for me the idea solution should be UITableViewController with static cells   You separate your UI to multiple part and put them in the tableViewCells one by one  than your don t need worry about keyboard anymore  tableViewController will manage it for you automatically    It may be a little difficult to calculate the padding  margin  cell height  but if your math is ok  it s simple

You will only need a ScrollView if the contents you have now do not fit in the iPhone screen   If you are adding the ScrollView as the superview of the components just to make the TextField scroll up when keyboard comes up  then it s not needed   The standard way to prevent the TextFields from being covered by the keyboard is to move the view up down whenever the keyboard is shown    Here is some sample code    define kOFFSET FOR KEYBOARD 80 0  - void keyboardWillShow          Animate the current view out of the way     if  self view frame origin y  gt   0                 self setViewMovedUp YES             else if  self view frame origin y  lt  0                 self setViewMovedUp NO            - void keyboardWillHide       if  self view frame origin y  gt   0                 self setViewMovedUp YES             else if  self view frame origin y  lt  0                 self setViewMovedUp NO            - void textFieldDidBeginEditing  UITextField   sender       if   sender isEqual mailTf                   move the main view  so that the keyboard does not hide it          if   self view frame origin y  gt   0                         self setViewMovedUp YES                        method to move the view up down whenever the keyboard is shown dismissed - void setViewMovedUp  BOOL movedUp        UIView beginAnimations nil context NULL        UIView setAnimationDuration 0 3      if you want to slide up the view      CGRect rect   self view frame      if  movedUp                   1  move the view s origin up so that the text field that will be hidden come above the keyboard             2  increase the size of the view so that the area behind the keyboard is covered up          rect origin y -  kOFFSET FOR KEYBOARD          rect size height    kOFFSET FOR KEYBOARD            else                  revert back to the normal state          rect origin y    kOFFSET FOR KEYBOARD          rect size height -  kOFFSET FOR KEYBOARD            self view frame   rect        UIView commitAnimations       -  void viewWillAppear  BOOL animated        super viewWillAppear animated          register for keyboard notifications       NSNotificationCenter defaultCenter  addObserver self                                          selector  selector keyboardWillShow                                               name UIKeyboardWillShowNotification                                            object nil          NSNotificationCenter defaultCenter  addObserver self                                          selector  selector keyboardWillHide                                               name UIKeyboardWillHideNotification                                            object nil      -  void viewWillDisappear  BOOL animated        super viewWillDisappear animated          unregister for keyboard notifications while not visible        NSNotificationCenter defaultCenter  removeObserver self                                              name UIKeyboardWillShowNotification                                            object nil          NSNotificationCenter defaultCenter  removeObserver self                                              name UIKeyboardWillHideNotification                                            object nil

Here is the hack solution I came up with for a specific layout  This solution is similar to Matt Gallagher solution in that is scrolls a section into view  I am still new to iPhone development  and am not familiar with how the layouts work  Thus  this hack   My implementation needed to support scrolling when clicking in a field  and also scrolling when the user selects next on the keyboard   I had a UIView with a height of 775  The controls are spread out basically in groups of 3 over a large space  I ended up with the following IB layout   UIView - gt  UIScrollView - gt   UI Components    Here comes the hack  I set the UIScrollView height to 500 units larger then the actual layout  1250   I then created an array with the absolute positions I need to scroll to  and a simple function to get them based on the IB Tag number   static NSInteger stepRange           0  0  0  0  0  0  0  0  0  140  140  140  140  140  410     NSInteger getScrollPos NSInteger i        if  i  lt  TXT FIELD INDEX MIN    i  gt  TXT FIELD INDEX MAX            return 0       return stepRange i        Now all you need to do is use the following two lines of code in textFieldDidBeginEditing and textFieldShouldReturn  the latter one if you are creating a next field navigation   CGPoint point   CGPointMake 0  getScrollPos textField tag      self scrollView setContentOffset point animated YES      An example   -  void  textFieldDidBeginEditing  UITextField   textField       CGPoint point   CGPointMake 0  getScrollPos textField tag          self scrollView setContentOffset point animated YES        -  BOOL textFieldShouldReturn  UITextField   textField        NSInteger nextTag   textField tag   1      UIResponder  nextResponder    textField superview viewWithTag nextTag        if  nextResponder             nextResponder becomeFirstResponder           CGPoint point   CGPointMake 0  getScrollPos nextTag              self scrollView setContentOffset point animated YES              else           textField resignFirstResponder              return YES       This method does not  scroll back  as other methods do  This was not a requirement  Again this was for a fairly  tall  UIView  and I did not have days to learn the internal layout engines

i had an issue with reseting to default main view while changing the text field or editing it s content  for example phone textfield and adding  -  sign  and view goes back covering textfields  i finnaly overcome this by using auto layout and changing constraints constant  not frame size or position in notification delegates functions  like this   P S  I m not using scrollview just simple move view up  but it should work similar  func keyboardWillShow notification  NSNotification    if let keyboardSize    notification userInfo  UIKeyboardFrameBeginUserInfoKey  as  NSValue   cgRectValue       if  keyboardIsShown          self infoViewTopConstraint constant -  keyboardSize height         self infoViewBottomConstraint constant    keyboardSize height         self view setNeedsLayout           self view layoutIfNeeded           keyboardIsShown   true          func keyboardWillHide notification  NSNotification    if keyboardIsShown       self infoViewTopConstraint constant    keyboardSize height     self infoViewBottomConstraint constant -  keyboardSize height     self view setNeedsLayout       self view layoutIfNeeded       keyboardIsShown   false

I ve developed a framework for my own need to solve this issue better  and made it public now  It s not just for UITextField and UITextView  It works for any custom UIView that adopts UITextInput protocol like UITextField and UITextView and offers many useful features  You can install it via Carthage  CocoaPods or Swift Package Manager   ODScrollView GitHub  ODScrollView Medium     ODScrollView is just a UIScrollView that automatically moves editable text areas like UITextField and UITextView vertically depending on keyboard visibility to offer better user experience    Features   Automatically moves first responder UIViews that adopt the UITextInput protocol up down when the keyboard appears disappears  e g   UITextField  UITextView  UISearchTextField or any custom UIView that adopts UITextInput protocol     Note that if UITextInput s frame does NOT fits the remaining area between ODScrollView and keyboard  then ODScrollView adjusts UITextInput based on cursor position instead of frame  In such cases   trackTextInputCursor  feature can be used  Example  Adjustment margin can be applied for each UITextInput seperately for  Top and  Bottom adjustment direction setting  20 CGFloat by default  Adjustment can be enabled disabled for each UITextInput seperately  true by default  Adjustment directon -  Top   Center   Bottom - can be applied for each UITextInput seperately   Bottom by default  Example Adjustment options determines how ODScrollView adjusts   Always by default     Always   ODScrollView always adjusts the UITextInput which is placed anywhere in the ODScrollView regardless UITextInput overlaps or not with shown keyboard  Example  IfNeeded   ODScrollView only adjusts the UITextInput if it overlaps with the shown keyboard  Example  Besides UIScrollView keyboardDismissModes  the keyboard can be dismissed by tapping a UIView which is provided by ODScrollViewDelegate  After the keyboard is dismissed  ODScrollView can return its original position  nil and false by default  Example   Usage  1 - First thing you need to do is setting up ODScrollView and its content view properly  Since ODScrollView is just a UIScrollView  you can implement ODScrollView same way you do for UIScrollView  It s up to you to create ODScrollView by using storyboard or programmatically    If you re creating ODScrollView programmatically  you can continue from step 4      Suggested way to create UIScrollView in Storyboard  - If you are using Content Layout Guide and Frame Layout Guide      1 1 - scrollView  Place UIScrollView anywhere you want to use        1 2 - contentView  Place UIView inside scrollView      1 3 - Set contentView s top  bottom  leading and trailing constraints to Content Layout Guide s constraints      1 4 - Set contentView s width equal to Frame Layout Guide s width      1 5 - Set contentView s height equal to Frame Layout Guide s height or set static height which is larger than scrollView s height      1 6 - Build your UI inside contentView   - If you are NOT using Content Layout Guide and Frame Layout Guide      1 1 - scrollView  Place UIScrollView anywhere you want to use        1 2 - contentView  Place UIView inside scrollView      1 3 - Set contentView s top  bottom  leading and trailing constraints to 0      1 4 - Set contentView s width equal to scrollView s width      1 5 - Set contentView s height equal to scrollView s superview s height or set static height which is larger than scrollView s height      1 6 - Build your UI inside contentView      2 - Change the scrollView s class from UIScrollView to ODScrollView in the identity inspector on Storyboard   3 - Create IBOutlets for scrollView and contentView on ViewController   4 - Call the following methods inside ViewDidLoad   on ViewController   override func viewDidLoad         super viewDidLoad          ODScrollView setup     scrollView registerContentView contentView      scrollView odScrollViewDelegate   self       5 - Optional  You still can use UIScrollView s features   override func viewDidLoad         super viewDidLoad          ODScrollView setup     scrollView registerContentView contentView      scrollView odScrollViewDelegate   self         UIScrollView setup     scrollView delegate   self    UIScrollView Delegate     scrollView keyboardDismissMode    onDrag    UIScrollView keyboardDismissMode  Default is  none       UITextView inside contentView delegate   self     6 - Adopt ODScrollViewDelegate from ViewController and decide ODScrollView options   extension ViewController  ODScrollViewDelegate           MARK - State Notifiers  are responsible for notifiying ViewController about what is going on while adjusting  You don t have to do anything if you don t need them           Optional        Notifies when the keyboard showed      func keyboardDidShow by scrollView  ODScrollView              Optional        Notifies before the UIScrollView adjustment      func scrollAdjustmentWillBegin by scrollView  ODScrollView              Optional        Notifies after the UIScrollView adjustment      func scrollAdjustmentDidEnd by scrollView  ODScrollView              Optional        Notifies when the keyboard hid      func keyboardDidHide by scrollView  ODScrollView             MARK - Adjustment Settings          Optional        Specifies the margin between UITextInput and ODScrollView s top or bottom constraint depending on AdjustmentDirection     func adjustmentMargin for textInput  UITextInput  inside scrollView  ODScrollView  -

Always   ODScrollView always adjusts the UITextInput which is placed anywhere in the ODScrollView       - IfNeeded   ODScrollView only adjusts the UITextInput if it overlaps with the shown keyboard              func adjustmentOption for scrollView  ODScrollView  -
