After you exit from one text field  you call  otherTextField becomeFirstResponder  and the next field gets focus   This can actually be a tricky problem to deal with since often you ll also want to scroll the screen or otherwise adjust the position of the text field so it s easy to see when editing   Just make sure to do a lot of testing with coming into and out of the text fields in different ways and also leaving early  always give the user an option to dismiss the keyboard instead of going to the next field  usually with  Done  in the nav bar

There is a much more elegant solution which blew me away the first time I saw it  Benefits    Closer to OSX textfield implementation where a textfield knows where the focus should go next Does not rely on setting or using tags -- which are  IMO fragile for this use case Can be extended to work with both UITextField and UITextView controls -- or any keyboard entry UI control Doesn t clutter your view controller with boilerplate UITextField delegate code Integrates nicely with IB and can be configured through the familiar option-drag-drop to connect outlets    Create a UITextField subclass which has an IBOutlet property called nextField  Here s the header    interface SOTextField   UITextField   property  weak  nonatomic  IBOutlet UITextField  nextField     end   And here s the implementation    implementation SOTextField   end   In your view controller  you ll create the -textFieldShouldReturn  delegate method   -  BOOL textFieldShouldReturn  UITextField   textField       if   textField isKindOfClass  SOTextField class              UITextField  nextField     SOTextField   textField nextField            if  nextField                dispatch async dispatch get current queue                        nextField becomeFirstResponder                                     else                textField resignFirstResponder                        return YES      In IB  change your UITextFields to use the SOTextField class  Next  also in IB  set the delegate for each of the  SOTextFields to  File s Owner   which is right where you put the code for the delegate method - textFieldShouldReturn   The beauty of this design is that now you can simply right-click on any textField and assign the nextField outlet to the next SOTextField object you want to be the next responder      Moreover  you can do cool things like loop the textFields so that after the last one loses focus  the first one will receive focus again   This can easily be extended to automatically assign the returnKeyType of the SOTextField to a UIReturnKeyNext if there is a nextField assigned -- one less thing manually configure

A safer and more direct way  assuming    the text field delegates are set to your view controller all of the text fields are subviews of the same view the text fields have tags in the order you want to progress  e g   textField2 tag   2  textField3 tag   3  etc   moving to the next text field will happen when you tap the return button on the keyboard  you can change this to next  done  etc   you want the keyboard to dismiss after the last text field   Swift 4 1   extension ViewController  UITextFieldDelegate       func textFieldShouldReturn   textField  UITextField  - gt  Bool           let nextTag   textField tag   1         guard let nextTextField   textField superview  viewWithTag nextTag  else               textField resignFirstResponder               return false                nextTextField becomeFirstResponder        return false

A more consistent and robust way is to use NextResponderTextField You can configure it totally from interface builder with no need for setting the delegate or using view tag   All you need to do is    Set the class type of your UITextField to be NextResponderTextField   Then set the outlet of the nextResponderField to point to the next responder it can be anything UITextField or any UIResponder subclass  It can be also a UIButton and the library is smart enough to trigger the TouchUpInside event of the button only if it s enabled      Here is the library in action

I like the OO solutions that have already been suggested by Anth0 and Answerbot  However  I was working on a quick and small POC  so I didn t want to clutter things with subclasses and categories   Another simple solution is to create an NSArray of fields and lookup the next field when you press next  Not an OO solution  but quick  simple  and easy to implement  Also  you can see and modify the ordering at a glance    Here s my code  built upon other answers in this thread     property  nonatomic  NSArray  fieldArray   -  void viewDidLoad        super viewDidLoad        fieldArray    NSArray arrayWithObjects  firstField  secondField  thirdField  nil      -  BOOL  textFieldShouldReturn  UITextField    textField       BOOL didResign    textField resignFirstResponder       if   didResign  return NO       NSUInteger index    self fieldArray indexOfObject textField       if  index    NSNotFound    index   1    fieldArray count  return NO       id nextField    fieldArray objectAtIndex index   1       activeField   nextField       nextField becomeFirstResponder        return NO       I always return NO because I don t want a line break inserted  Just thought I d point that out since when I returned YES it would automatically exit the subsequent fields or insert a line break in my TextView  It took me a bit of time to figure that out  activeField keeps track of the active field in case scrolling is necessary to unobscure the field from the keyboard  If you have similar code  make sure you assign the activeField before changing the first responder  Changing first responder is immediate and will fire the KeyboardWasShown event immediately

This is an old post  but has a high page rank so I ll chime in with my solution   I had a similar issue and ended up creating a subclass of UIToolbar to manage the next previous done functionality in a dynamic tableView with sections  https   github com jday001 DataEntryToolbar  You set the toolbar as inputAccessoryView of your text fields and add them to its dictionary  This allows you to cycle through them forwards and backwards  even with dynamic content  There are delegate methods if you want to trigger your own functionality when textField navigation happens  but you don t have to deal with managing any tags or first responder status   There are code snippets  amp  an example app at the GitHub link to help with the implementation details  You will need your own data model to keep track of the values inside the fields

I am surprised by how many answers here fail to understand one simple concept  navigating through controls in your app is not something the views themselves should do  It s the controller s job to decide which control to make the next first responder   Also most answers only applied to navigating forward  but users may also want to go backwards   So here s what I ve come up with  Your form should be managed by a view controller  and view controllers are part of the responder chain  So you re perfectly free to implement the following methods    pragma mark - Key Commands  -  NSArray   keyCommands       static NSArray  commands       static dispatch once t once      dispatch once  amp once             UIKeyCommand  const forward    UIKeyCommand keyCommandWithInput    t  modifierFlags 0 action  selector tabForward             UIKeyCommand  const backward    UIKeyCommand keyCommandWithInput    t  modifierFlags UIKeyModifierShift action  selector tabBackward              commands     forward  backward                return commands     -  void tabForward  UIKeyCommand   command       NSArray  const controls   self controls      UIResponder  firstResponder   nil       for  UIResponder  const responder in controls            if  firstResponder    nil  amp  amp  responder canBecomeFirstResponder                 responder becomeFirstResponder   return                    else if  responder isFirstResponder                firstResponder   responder                        controls firstObject becomeFirstResponder      -  void tabBackward  UIKeyCommand   command       NSArray  const controls   self controls      UIResponder  firstResponder   nil       for  UIResponder  const responder in controls reverseObjectEnumerator            if  firstResponder    nil  amp  amp  responder canBecomeFirstResponder                 responder becomeFirstResponder   return                    else if  responder isFirstResponder                firstResponder   responder                        controls lastObject becomeFirstResponder       Additional logic for scrolling offscreen responders visible beforehand may apply   Another advantage of this approach is that you don t need to subclass all kinds of controls you may want to display  like UITextFields  but can instead manage the logic at controller level  where  let s be honest  is the right place to do so

I rather prefer to    interface MyViewController   UIViewController  property  nonatomic  retain  IBOutletCollection UIView  NSArray  inputFields   end   In the NIB file I hook the textFields in the desired order into this inputFields array  After that I do a simple test for the index of the UITextField that reports that the user tapped return      for UITextField - BOOL textFieldShouldReturn  UITextField  textField       NSUInteger index     inputFields indexOfObject textField       index        if  index  lt   inputFields count            UIView  v     inputFields objectAtIndex index            v becomeFirstResponder             return NO        for UITextView - BOOL textView  UITextView  textView shouldChangeTextInRange  NSRange range replacementText  NSString  text       if      n  isEqualToString text             NSUInteger index     inputFields indexOfObject textView           index            if  index  lt   inputFields count                UIView  v     inputFields objectAtIndex index                v becomeFirstResponder             else                self view endEditing YES                     return NO            return YES

I tried to solve this problem using a more sophisticated approach based on assigning each cell  or UITextField  in a UITableView a unique tag value that can be later retrieved  activate-next-uitextfield-in-uitableview-ios  I hope this helps

Here is my solution for this problem   To solve this  and because I hate relying on tags to do stuff  I decided to add a custom property to the UITextField object  In other words I created a category on UITextField like this    UITextField Extended h   interface UITextField  Extended    property retain  nonatomic UITextField  nextTextField    end   UITextField Extended m   import  UITextField Extended h   import  lt objc runtime h gt   static char defaultHashKey    implementation UITextField  Extended   -  UITextField   nextTextField        return objc getAssociatedObject self   amp defaultHashKey       -  void  setNextTextField  UITextField   nextTextField      objc setAssociatedObject self   amp defaultHashKey  nextTextField  OBJC ASSOCIATION RETAIN NONATOMIC        end   Now  here is how I use it    UITextField  textField1      init your textfield UITextField  textField2      init your textfield UITextField  textField3      init your textfield  textField1 nextTextField   textField2  textField2 nextTextField   textField3  textField3 nextTextField   nil    And implement the textFieldShouldReturn method    -  BOOL textFieldShouldReturn  UITextField   theTextField        UITextField  next   theTextField nextTextField      if  next             next becomeFirstResponder         else            theTextField resignFirstResponder              return NO       I now have kind of a linked list of UITextField  each one knowing who s next in the line   Hope it ll help

Here s one without delegation   tf1 addTarget tf2  action   selector becomeFirstResponder   for   editingDidEndOnExit  tf2 addTarget tf3  action   selector becomeFirstResponder   for   editingDidEndOnExit    ObjC    tf1 addTarget tf2 action  selector becomeFirstResponder  forControlEvents UIControlEventEditingDidEndOnExit    tf2 addTarget tf3 action  selector becomeFirstResponder  forControlEvents UIControlEventEditingDidEndOnExit     Works using the  mostly unknown  UIControlEventEditingDidEndOnExit UITextField action   You can also easily hook this up in the storyboard  so no delegation or code is required   Edit  actually I cannot figure out how to hook this up in storyboard  becomeFirstResponder does not seem to be a offered action for this control-event  which is a pity  Still  you can hook all your textfields up to a single action in your ViewController which then determines which textField to becomeFirstResponder based on the sender  though then it is not as elegant as the above programmatic solution so IMO do it with the above code in viewDidLoad

This worked for me in Xamarin iOS   Monotouch  Change the keyboard button to Next  pass the control to the next UITextField and hide the keyboard after the last UITextField   private void SetShouldReturnDelegates IEnumerable lt UIView gt  subViewsToScout       foreach  var item in subViewsToScout Where item   gt  item GetType      typeof  UITextField             item as UITextField  ReturnKeyType   UIReturnKeyType Next       item as UITextField  ShouldReturn     textField    gt                nint nextTag   textField Tag   1          var nextResponder   textField Superview ViewWithTag nextTag           if  null    nextResponder              nextResponder BecomeFirstResponder            else             textField Superview EndEditing true                  You could also use textField ResignFirstResponder              return false     We do not want UITextField to insert line-breaks                 Inside the ViewDidLoad you ll have   If your TextFields haven t a Tag set it now   txtField1 Tag   0  txtField2 Tag   1  txtField3 Tag   2          and just the call  SetShouldReturnDelegates yourViewWithTxtFields Subviews ToList       If you are not sure of which view contains your fields you can also call it in a safer way  SetShouldReturnDelegates txtField1 Superview Subviews ToList       You can also reuse the same method with different containerViews in case your UITextField are under different views

I had about 10  UITextField in my story board and the way I enabled next functionality was by creating an array of UITextField and making the next UITextField the firstResponder  Here s the implementation file    import  RegistrationTableViewController h    interface RegistrationTableViewController     property  weak  nonatomic  IBOutlet UITextField  fullNameTextField   property  weak  nonatomic  IBOutlet UITextField  addressTextField   property  weak  nonatomic  IBOutlet UITextField  address2TextField   property  weak  nonatomic  IBOutlet UITextField  cityTextField   property  weak  nonatomic  IBOutlet UITextField  zipCodeTextField   property  weak  nonatomic  IBOutlet UITextField  urlTextField   property  weak  nonatomic  IBOutlet UITextField  usernameTextField   property  weak  nonatomic  IBOutlet UITextField  emailTextField   property  weak  nonatomic  IBOutlet UITextField  passwordTextField   property  weak  nonatomic  IBOutlet UITextField  confirmPWTextField    end NSArray  uiTextFieldArray   implementation RegistrationTableViewController  -  void viewDidLoad        super viewDidLoad       NSLog   view did load        uiTextFieldArray     self fullNameTextField self addressTextField self address2TextField self cityTextField self zipCodeTextField self urlTextField self usernameTextField self emailTextField self passwordTextField self confirmPWTextField       for UITextField  myField in uiTextFieldArray           myField delegate   self            - BOOL textFieldShouldReturn  UITextField   textField      long index    uiTextFieldArray indexOfObject textField       NSLog    ld  index       if index  lt   uiTextFieldArray count - 1             uiTextFieldArray   index  becomeFirstResponder        else           uiTextFieldArray index  resignFirstResponder             return YES    -  void didReceiveMemoryWarning        super didReceiveMemoryWarning          Dispose of any resources that can be recreated      end

I ve just created new Pod when dealing with this stuff GNTextFieldsCollectionManager  It automatically handles next last textField problem and is very easy to use     GNTextFieldsCollectionManager alloc  initWithView self view     Grabs all textfields sorted by appearing in view hierarchy  or by tags   or you can specify your own array of textFields

I have added to PeyloW s answer in case you re looking to implement a previous next button functionality   -  IBAction moveThroughTextFields  UIBarButtonItem   sender        NSInteger nextTag      UITextView  currentTextField    self view findFirstResponderAndReturn        if  currentTextField    nil               I assigned tags to the buttons   0 represent prev  amp  1 represents next         if  sender tag    0                nextTag   currentTextField tag - 1             else if  sender tag    1                nextTag   currentTextField tag   1                         Try to find next responder     UIResponder  nextResponder    self view viewWithTag nextTag       if  nextResponder               Found next responder  so set it             I added the resign here in case there s different keyboards in place           currentTextField resignFirstResponder            nextResponder becomeFirstResponder         else              Not found  so remove keyboard           currentTextField resignFirstResponder              Where you subclass the UIView like this    implementation UIView  FindAndReturnFirstResponder  -  UITextView   findFirstResponderAndReturn       for  UITextView  subView in self subviews            if  subView isFirstResponder               return subView                      return nil     end

If someone wants like this  I think this is the closest to the requirements asked for in question     Here is how I have implemented this one  Add accessory view for each text field for which you want the setup  using   func setAccessoryViewFor textField   UITextField           let toolBar   UIToolbar       toolBar barStyle    default     toolBar isTranslucent   true     toolBar sizeToFit           Adds the buttons         Add previousButton     let prevButton   UIBarButtonItem title    lt    style   plain  target  self  action   selector previousPressed sender         prevButton tag   textField tag     if getPreviousResponderFor tag  textField tag     nil           prevButton isEnabled   false               Add nextButton     let nextButton   UIBarButtonItem title    gt    style   plain  target  self  action   selector nextPressed sender         nextButton tag   textField tag     if getNextResponderFor tag  textField tag     nil           nextButton title    Done             let spaceButton   UIBarButtonItem barButtonSystemItem   flexibleSpace  target  nil  action  nil      toolBar setItems  prevButton spaceButton nextButton   animated  false      toolBar isUserInteractionEnabled   true     textField inputAccessoryView   toolBar     Use following functions to handle taps   func nextPressed sender   UIBarButtonItem        if let nextResponder   getNextResponderFor tag  sender tag            nextResponder becomeFirstResponder         else           self view endEditing true            func previousPressed sender   UIBarButtonItem        if let previousResponder   getPreviousResponderFor tag   sender tag             previousResponder becomeFirstResponder            func getNextResponderFor tag   Int  - gt  UITextField        return self view viewWithTag tag   1  as  UITextField    func getPreviousResponderFor tag   Int  - gt  UITextField        return self view viewWithTag tag - 1  as  UITextField     You will need to give the textFields tags in sequence in which you want the next prev button to respond

In Cocoa for Mac OS X  you have the next responder chain  where you can ask the text field what control should have focus next  This is what makes tabbing between text fields work  But since iOS devices do not have a keyboard  only touch  this concept has not survived the transition to Cocoa Touch   This can be easily done anyway  with two assumptions    All  tabbable  UITextFields are on the same parent view  Their  tab-order  is defined by the tag property    Assuming this you can override textFieldShouldReturn  as this   - BOOL textFieldShouldReturn  UITextField  textField     NSInteger nextTag   textField tag   1       Try to find next responder   UIResponder  nextResponder    textField superview viewWithTag nextTag     if  nextResponder           Found next responder  so set it       nextResponder becomeFirstResponder       else          Not found  so remove keyboard       textField resignFirstResponder         return NO     We do not want UITextField to insert line-breaks      Add some more code  and the assumptions can be ignored as well   Swift 4 0   func textFieldShouldReturn   textField  UITextField  - gt  Bool       let nextTag   textField tag   1        Try to find next responder     let nextResponder   textField superview  viewWithTag nextTag  as UIResponder       if nextResponder    nil              Found next responder  so set it         nextResponder  becomeFirstResponder         else              Not found  so remove keyboard         textField resignFirstResponder              return false     If the superview of the text field will be a UITableViewCell then next responder will be  let nextResponder   textField superview  superview  superview  viewWithTag nextTag  as UIResponder
