Move view with keyboard using Swift

Question

I have an app that has a text field on the lower half of the view  This means that when I go to type in the text field the keyboard covers the textfield   How would I go about moving the view upwards while typing so I can see what i m typing and then moving it back down to its original place when the keyboard disappears   I ve looked everywhere but all the solutions appear to be in Obj-C which I can t quite convert just yet   Any help would be greatly appreciated

Moving origin of the view is a naive approach.

Here is the better solution: Adjust the height of the view when the keyboard appears.

let viewHeight = self.view.frame.height

    override func viewDidLoad() {
        super.viewDidLoad()

        NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name: UIResponder.keyboardWillShowNotification, object: nil)
        NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide), name: UIResponder.keyboardWillHideNotification, object: nil)
    }

    @objc func keyboardWillShow(notification: NSNotification) {
        if let keyboardSize = (notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
            if self.view.frame.height == self.viewHeight{
                self.view.frame = CGRect(x: 0, y: 0, width: self.view.frame.width, height: self.view.frame.height - keyboardSize.height)
            }

        }
    }

    @objc func keyboardWillHide(notification: NSNotification) {
        if let keyboardSize = (notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {

            self.view.frame = CGRect(x: 0, y: 0, width: self.view.frame.width, height: self.view.frame.height + keyboardSize.height)
        }
    }

Since there were no answer on how to do this in Combine  here is the approach i used   We create a publisher to listen to both Notifications  show and hide  For show we get the frame of the keyboard from the notifications userInfo and check if the current active responder is contained in it  If it s covered return keyboard frame height  If it is not covered return 0  we don t want to move the frame  For the hide notification we simply return 0   private var keyboardHeightPublisher  AnyPublisher lt CGFloat  Never gt        Publishers Merge          NotificationCenter default              publisher for  UIResponder keyboardWillShowNotification               compactMap    0 userInfo  UIResponder keyboardFrameEndUserInfoKey  as  CGRect                map    0 intersects self view firstResponder  frame     0 height   0                map    0   -1            NotificationCenter default              publisher for  UIResponder keyboardWillHideNotification               map     in CGFloat 0          eraseToAnyPublisher      In the viewDidLoad we simply subscribe to the publisher changing the views frame accordingly  override func viewDidLoad         super viewDidLoad        keyboardHeightPublisher sink   weak self  height in         self  view frame origin y   height       store in   amp cancelables     EDIT Be careful  If the firstResponder is in a subview  you have to calculate the frame corresponding to the whole screen to check if they actually intersect  Example  let myViewGlobalFrame   myView convert myView frame  to  parentView

Easiest way that doesn t even require any code    Download KeyboardLayoutConstraint swift and add  drag  amp  drop  the file into your project  if you re not using the Spring animation framework already  In your storyboard  create a bottom constraint for the View or Textfield  select the constraint  double-click it  and in the Identity Inspector  change its class from NSLayoutConstraint to KeyboardLayoutConstraint  Done     The object will auto-move up with the keyboard  in sync

For Swift 3  I made a UIViewController subclass since I needed constant behavior in all View Controllers    class SomeClassVC  UIViewController        MARK  - Lifecycle   override func viewDidLoad         super viewDidLoad        addKeyboardObservers          override func viewWillDisappear   animated  Bool        super viewWillDisappear animated       removeKeyboardObservers            MARK  - Overrides   override func touchesBegan   touches  Set lt UITouch gt   with event  UIEvent         view endEditing true           MARK  - Help   func addKeyboardObservers         NotificationCenter default addObserver self  selector   selector self keyboardWillShow   name  NSNotification Name UIKeyboardWillShow  object  nil      NotificationCenter default addObserver self  selector   selector self keyboardWillHide   name  NSNotification Name UIKeyboardWillHide  object  nil         func removeKeyboardObservers         NotificationCenter default removeObserver self  name  NSNotification Name UIKeyboardWillShow  object  self view window      NotificationCenter default removeObserver self  name  NSNotification Name UIKeyboardWillHide  object  self view window         func keyboardWillShow notification  NSNotification        let keyboardHeight    notification userInfo  UIKeyboardFrameBeginUserInfoKey  as  NSValue   cgRectValue height     UIView animate withDuration  0 1  animations       - gt  Void in       self view window  frame origin y   -1   keyboardHeight        self view layoutIfNeeded                 func keyboardWillHide notification  NSNotification        UIView animate withDuration  0 1  animations       - gt  Void in       self view window  frame origin y   0       self view layoutIfNeeded                 func resignTextFieldFirstResponders         for textField in self view subviews where textField is UITextField         textField resignFirstResponder                func resignAllFirstResponders           view endEditing true

This implementation  Swift 4  will give you the behaviour that comes closest to the default behaviour of Android  Ie  moves the view up when the active textfield is under the keyboard and moves accordingly when the user switches to another view without closing the keyboard  Remember to call setTextFieldDelegates     public class DelegateProxy  NSObject  UITextFieldDelegate      private static let instance   DelegateProxies      weak var activeTextField  UITextField    var offset  CGFloat   0   weak var vc  UIViewController    var keyboardHeight  CGFloat   0    public static func getDelegate root  UIViewController  - gt  DelegateProxies       instance vc   root     return instance        public static func getDelegate   - gt  DelegateProxies       return instance        public func textFieldShouldReturn   textField  UITextField  - gt  Bool       textField resignFirstResponder       return true         public func textFieldShouldBeginEditing   textField  UITextField  - gt  Bool        self activeTextField   textField      let globalPointY  CGFloat    textField superview  convert textField frame origin  to  nil  y    CGFloat 0     textField frame height       offset   UIScreen main bounds height - globalPointY      if keyboardHeight  gt  0           vc  moveViewUp offsetFromKeyboard  keyboardHeight - offset             return true         extension UIViewController      private func setTextFieldDelegates parentView  UIView        for child in parentView subviews           setTextFieldDelegates parentView  child           child as  UITextField   delegate   DelegateProxies getDelegate root  self               func registerAutoResizeOnKeyboardAppear        NotificationCenter default addObserver self  selector   selector keyboardWillShow   name  NSNotification Name UIKeyboardWillShow  object  nil      NotificationCenter default addObserver self  selector   selector keyboardWillHide   name  NSNotification Name UIKeyboardWillHide  object  nil         func unregisterAutoResizeOnKeyboard        NotificationCenter default removeObserver self  name  NSNotification Name UIKeyboardWillShow  object  nil      NotificationCenter default removeObserver self  name  NSNotification Name UIKeyboardWillHide  object  nil          objc func keyboardWillShow notification  NSNotification         if let keyboardSize    notification userInfo  UIKeyboardFrameEndUserInfoKey  as  NSValue   cgRectValue           let offsetFromKeyboard   keyboardSize height - DelegateProxies getDelegate   offset         DelegateProxies getDelegate   keyboardHeight   keyboardSize height          moveViewUp offsetFromKeyboard  offsetFromKeyboard               func moveViewUp offsetFromKeyboard  CGFloat       print  offset from keyboard    offsetFromKeyboard         let moveOffset   offsetFromKeyboard   8      if offsetFromKeyboard  gt  0           self view frame origin y   -moveOffset            if offsetFromKeyboard  lt  0  amp  amp  view frame origin y  lt  0           self view frame origin y    -moveOffset         if self view frame origin y  gt  0              self view frame origin y   0                         objc func keyboardWillHide notification  NSNotification        self view frame origin y   0

The validated answer doesn t take in account the textfield position and has some bug  double displacement  never come back the primary position  displacement even if the texfield is on top of the view      The idea is      to get the focus TextField absolute Y position to get the keyboard height to get the ScreenHeight Then calculate the distance between keyboard position and textfield  if  lt  0 -  move up the view  to use UIView transform instead of UIView frame origin y -      cause it s easier to come back to original position with UIView transform    identity   then we will be able to move the view only if necessary and of the specific displacement in oder to have the focused texField just over the keyboard  Here is the code     Swift 4     class ViewController  UIViewController  UITextFieldDelegate    var textFieldRealYPosition  CGFloat   0 0  override func viewDidLoad         super viewDidLoad        NotificationCenter default addObserver self  selector   selector VehiculeViewController keyboardWillShow   name  NSNotification Name UIKeyboardWillShow  object  nil      NotificationCenter default addObserver self  selector   selector VehiculeViewController keyboardWillHide   name  NSNotification Name UIKeyboardWillHide  object  nil        Delegate all textfields       objc func keyboardWillShow notification  NSNotification        if let keyboardSize    notification userInfo  UIKeyboardFrameBeginUserInfoKey  as  NSValue   cgRectValue           let distanceBetweenTextfielAndKeyboard   self view frame height - textFieldRealYPosition - keyboardSize height         if distanceBetweenTextfielAndKeyboard  lt  0               UIView animate withDuration  0 4                    self view transform   CGAffineTransform translationX  0 0  y  distanceBetweenTextfielAndKeyboard                                     objc func keyboardWillHide notification  NSNotification        UIView animate withDuration  0 4            self view transform    identity           func textFieldDidBeginEditing   textField  UITextField      textFieldRealYPosition   textField frame origin y   textField frame height     take in account all superviews from textfield and potential contentOffset if you are using tableview to calculate the real position

If you have 2 or more text fields on the same VC  and the user taps on one of them and then taps on the other one  without calling the function keyboardWillHide  the view is going upwards one more time  which is not necessary  because you ll have the keyboard  a blank space which has the height of the keyboard  and then the view  using the code in the answer I edited   override func viewDidLoad                super viewDidLoad       NSNotificationCenter defaultCenter   addObserver self  selector  Selector  keyboardWillShow     name  UIKeyboardWillShowNotification  object  nil      NSNotificationCenter defaultCenter   addObserver self  selector  Selector  keyboardWillHide     name  UIKeyboardWillHideNotification  object  nil     func keyboardWillShow notification  NSNotification        if let keyboardSize    notification userInfo  UIKeyboardFrameBeginUserInfoKey  as  NSValue   CGRectValue             self view frame origin y -  keyboardSize height          func keyboardWillHide notification  NSNotification        if let keyboardSize    notification userInfo  UIKeyboardFrameBeginUserInfoKey  as  NSValue   CGRectValue             self view frame origin y    keyboardSize height           To solve this  replace the two functions  KeyboardWillShow Hide  to these   func keyboardWillShow notification  NSNotification     if let keyboardSize    notification userInfo  UIKeyboardFrameBeginUserInfoKey  as  NSValue   CGRectValue         if view frame origin y    0          self view frame origin y -  keyboardSize height                    func keyboardWillHide notification  NSNotification        if let keyboardSize    notification userInfo  UIKeyboardFrameBeginUserInfoKey  as  NSValue   CGRectValue             if view frame origin y    0               self view frame origin y    keyboardSize height

I noticed that the other answers involved cutting some of the top from the view  If you want to simply resize the view without cutting any content  just try this method     func keyboardWillShow notification  NSNotification        if let keyboardSize    notification userInfo  UIKeyboardFrameBeginUserInfoKey  as  NSValue   CGRectValue             self view setTranslatesAutoresizingMaskIntoConstraints true          self view frame   CGRectMake self view frame origin x  self view frame origin y  self view frame size width  self view frame height - keyboardSize height           func keyboardWillHide notification  NSNotification        if let keyboardSize    notification userInfo  UIKeyboardFrameBeginUserInfoKey  as  NSValue   CGRectValue             self collectionView setTranslatesAutoresizingMaskIntoConstraints false          self view frame   CGRectMake self view frame origin x  self view frame origin y  self view frame size width  self view frame height   keyboardSize height

this video tutorial is the best  7 mins long and it ll just make so much sense  Such a simple solution for when you have multiple text fields and want the scroll view to move  x  amount of pixels when that specific textfield is tapped   https   youtu be VuiPGJOEBH4  Just these steps   -Place all your textfields within a scrollview that is constrained to the edges of the view    -Connect all the textfields and scroll view as delegates to the view controller   -Connect all textfields and scroll view with an IBOutlet   class ViewController  UIViewController  UITextFieldDelegate     -Add UITextFieldDelegate protocol to your class   IBOutlet var stateAddress  UITextField   IBOutlet var zipAddress  UITextField   IBOutlet var phoneNumber  UITextField   IBOutlet var vetEmailAddress  UITextField       IBOutlet weak var scrollView  UIScrollView    -Add UITextFieldDelegate methods to your swift file   func textFieldShouldReturn textField  UITextField  - gt  Bool        textField resignFirstResponder       return true     func textFieldDidBeginEditing textField  UITextField         if  textField    self stateAddress            scrollView setContentOffset CGPointMake 0  25   animated  true            else if  textField    self zipAddress            scrollView setContentOffset CGPointMake 0  57   animated  true            else if  textField    self phoneNumber            scrollView setContentOffset CGPointMake 0  112   animated  true            else if  textField    self vetEmailAddress            scrollView setContentOffset CGPointMake 0  142   animated  true           func textFieldDidEndEditing textField  UITextField         scrollView setContentOffset CGPointMake 0  0   animated  true      The first method just activates the return button on the keyboard to dismiss the keyboard  The second is when you tap into whatever specific textfield then setting the y offset of how far your scrollview scrolls  mine is based off of the y location on my view controllers 25 57 112 142   The last says when you tap away from the keyboard the scrollview goes back to original location   I made my view pixel perfect this way

Not an advertisement or promotion or spam  just a good solution  I know that this question has nearly 30 answers and I m so shocked that no one even mentioned once about this beautiful GitHub project that does it all for you and even better  All the answers just move the view upwards  I just solved all my problems with this IQKeyboardManager  It has 13000  stars   Just add this in your podfile if you are using swift  pod  IQKeyboardManagerSwift    and then inside your AppDelegate swift do import IQKeyboardManagerSwift  import IQKeyboardManagerSwift   UIApplicationMain class AppDelegate  UIResponder  UIApplicationDelegate        var window  UIWindow       func application application  UIApplication  didFinishLaunchingWithOptions launchOptions   NSObject  AnyObject    - gt  Bool          IQKeyboardManager shared enable   true    just add this line        return true           Add the line IQKeyboardManager shared enable   true to enable it  This solution is a must if you are going for production

Updated for Swift 3     As others have said  you need to add notification observers in your controller s viewDidLoad   method  like so   NotificationCenter default addObserver forName   UIKeyboardWillShow  object  nil  queue  nil        notification in     self keyboardWillShow notification         NotificationCenter default addObserver forName   UIKeyboardWillHide  object  nil  queue  nil        notification in     self keyboardWillHide notification         NotificationCenter default addObserver forName   UIKeyboardDidShow  object  nil  queue  nil          in     self enableUserInteraction          NotificationCenter default addObserver forName   UIKeyboardDidHide  object  nil  queue  nil          in     self enableUserInteraction           Remember to remove your observers where appropriate  I do it in the viewWillDisappear   method   NotificationCenter default removeObserver self  name   UIKeyboardWillShow  object  nil  NotificationCenter default removeObserver self  name   UIKeyboardWillHide  object  nil  NotificationCenter default removeObserver self  name   UIKeyboardDidShow  object  nil  NotificationCenter default removeObserver self  name   UIKeyboardDidHide  object  nil    Then  implement your show and hide methods - notice the line that tells the app to ignore interaction events  beginIgnoringInteractionEvents    This is important since without it  the user could tap on a field or even a scrollview and cause the shift to occur a second time  resulting in a terrible UI glitch  Ignoring interaction events prior to the keyboard showing and hiding will prevent this   func keyboardWillShow notification  Notification            if let keyboardSize    notification userInfo  UIKeyboardFrameBeginUserInfoKey  as  NSValue   cgRectValue                   UIApplication shared beginIgnoringInteractionEvents           self view frame origin y -  keyboardSize height            add this line if you are shifting a scrollView  as in a chat application         self timelineCollectionView contentInset top    keyboardSize height                  func keyboardWillHide notification  Notification            if let keyboardSize    notification userInfo  UIKeyboardFrameBeginUserInfoKey  as  NSValue   cgRectValue                   UIApplication shared beginIgnoringInteractionEvents           self view frame origin y    keyboardSize height            add this line if you are shifting a scrollView  as in a chat application         self timelineCollectionView contentInset top -  keyboardSize height                   Lastly  re-enable user interactions  remember  this method fires after the keyboard didShow or didHide    func enableUserInteraction             UIApplication shared endIgnoringInteractionEvents

I see all answers are moving the view itself by the value of the keyboard height  Well  I have an elaborate answer  which could be useful if you are using constraints i e autolayout  that moves a view by changing its constraint value  bottom or top constraints for example  by a predefined value or you can use keyboard size value   In this example  I use bottom constraint from the textfield to Bottom Layout View with initial value of 175    IBOutlet weak var bottomConstraint  NSLayoutConstraint   override func viewDidLoad         super viewDidLoad               NSNotificationCenter defaultCenter   addObserver self  selector  Selector  keyboardWillShow     name UIKeyboardWillShowNotification  object  nil       NSNotificationCenter defaultCenter   addObserver self  selector  Selector  keyboardWillHide     name UIKeyboardWillHideNotification  object  nil      func keyboardWillShow notification  NSNotification          To retrieve keyboard size  uncomment following line       let keyboardSize    notification userInfo  UIKeyboardFrameBeginUserInfoKey  as  NSValue   CGRectValue       bottomConstraint constant   260     UIView animateWithDuration 0 3            self view layoutIfNeeded            func keyboardWillHide notification  NSNotification          To retrieve keyboard size  uncomment following line       let keyboardSize    notification userInfo  UIKeyboardFrameBeginUserInfoKey  as  NSValue   CGRectValue       bottomConstraint constant   175     UIView animateWithDuration 0 3            self view layoutIfNeeded

My two cents for beginners  in above samples someone changes coordinates  other uses  autoresizing mask   and other constraints   As Apple says  do not mix these 3 types of logic  If You have constraints in Storyboard  do not try to change x y  It definitively not work
