How to show Done button on iPhone number pad

Question

There is no  Done  button on the number pad  When a user finishes entering numeric information in a text field  how can I make the number pad disappear   I could get a  Done  button by using the default keyboard  but then users would have to switch to the numeric keys in order to input numbers  Is there a way to show a  Done  button on the number pad

If you know in advance the number of numbers to be entered (e.g. a 4-digit PIN) you could auto-dismiss after 4 key presses, as per my answer to this similar question:

dismissing Number Pad

No need for an additional done button in this case.

A Swift 3 solution using an extension  Ideal if you have several numeric UITextField objects in your app as it gives the flexibility to decide  for each UITextField  whether to perform a custom action when Done or Cancel is tapped            UITextField DoneCancelToolbar swift     import UIKit  extension UITextField       func addDoneCancelToolbar onDone   target  Any  action  Selector     nil  onCancel   target  Any  action  Selector     nil                 let onCancel   onCancel     target  self  action   selector cancelButtonTapped           let onDone   onDone     target  self  action   selector doneButtonTapped            let toolbar  UIToolbar   UIToolbar           toolbar barStyle    default         toolbar items                 UIBarButtonItem title   Cancel   style   plain  target  onCancel target  action  onCancel action               UIBarButtonItem barButtonSystemItem   flexibleSpace  target  self  action  nil               UIBarButtonItem title   Done   style   done  target  onDone target  action  onDone action                    toolbar sizeToFit            self inputAccessoryView   toolbar               Default actions        func doneButtonTapped     self resignFirstResponder         func cancelButtonTapped     self resignFirstResponder         Example of usage using the default actions         MyViewController swift      IBOutlet weak var myNumericTextField  UITextField        didSet   myNumericTextField  addDoneCancelToolbar         Example of usage using a custom Done action         MyViewController swift      IBOutlet weak var myNumericTextField  UITextField        didSet            myNumericTextField  addDoneCancelToolbar onDone   target  self  action   selector doneButtonTappedForMyNumericTextField              func doneButtonTappedForMyNumericTextField          print  Done         myNumericTextField resignFirstResponder

The trick I ve seen used is to make a custom transparent button the size of the whole view and then in its click method  have the text field resign first responder  So the user can click anywhere outside of the field to dismiss the keypad

Here is an adaptation for Luda s answer for Swift   In the declaration of your UIViewController subclass put  let numberToolbar  UIToolbar   UIToolbar     in ViewDidLoad put       numberToolbar barStyle   UIBarStyle BlackTranslucent     numberToolbar items           UIBarButtonItem title   Cancel   style  UIBarButtonItemStyle Bordered  target  self  action   hoopla            UIBarButtonItem barButtonSystemItem  UIBarButtonSystemItem FlexibleSpace  target  self  action  nil           UIBarButtonItem title   Apply   style  UIBarButtonItemStyle Bordered  target  self  action   boopla              numberToolbar sizeToFit        textField inputAccessoryView   numberToolbar   do it for every relevant textfield if there are more than one    and the add the functions hoopla and hoopla  feel free to choose other names  just change the selector names in ViewDidLoad accordingly  func boopla          textField resignFirstResponder      func hoopla          textField text        textField resignFirstResponder

A much easier solution  -  void touchesBegan  NSSet   touches withEvent  UIEvent   event          super touchesBegan touches withEvent event         textViewInstance1 resignFirstResponder        textViewInstance2 resignFirstResponder        textField resignFirstResponder

We can also make the  user touched somewhere else  solution even simpler if we just tell our view controller s view to end editing   - void touchesBegan  NSSet   touches withEvent  UIEvent   event             super touchesBegan touches withEvent event           self view endEditing YES     YES ignores any textfield refusal to resign          assuming that  touching elsewhere dismisses the keyboard  is desired behavior for any other editable fields on the view as well

All those implementation about finding the keyboard view and adding the done button at the 3rd row  that is why button y   163 b c keyboard s height is 216  are fragile because iOS keeps change the view hierarchy  For example none of above codes work for iOS9   I think it is more safe to just find the topmost view  by    UIApplication sharedApplication  windows  lastObject   and just add the button at bottom left corner of it  doneButton frame   CGRectMake 0  SCREEN HEIGHT-53  106  53     portrait mode

If you have multiple numeric fields  I suggest subclassing UITextField to create a NumericTextField that always displays a numeric keyboard with a done button  Then  simply associate your numeric fields with this class in the Interface Builder and you won t need any additional code in any of your View Controllers  The following is Swift 3 0 class that I m using in Xcode 8 0    class NumericTextField  UITextField      let numericKbdToolbar   UIToolbar           MARK  Initilization     required init  coder aDecoder  NSCoder            super init coder  aDecoder          self initialize              override init frame  CGRect            super init frame  frame          self initialize                 Sets up the input accessory view with a Done button that closes the keyboard     func initialize                 self keyboardType   UIKeyboardType numberPad          numericKbdToolbar barStyle   UIBarStyle default         let space   UIBarButtonItem barButtonSystemItem  UIBarButtonSystemItem flexibleSpace  target  nil  action  nil          let callback    selector NumericTextField finishedEditing          let donebutton   UIBarButtonItem barButtonSystemItem  UIBarButtonSystemItem done  target  self  action  callback          numericKbdToolbar setItems  space  donebutton   animated  false          numericKbdToolbar sizeToFit           self inputAccessoryView   numericKbdToolbar               MARK  On Finished Editing Function     func finishedEditing                 self resignFirstResponder             Swift 4 2  class NumericTextField  UITextField       let numericKbdToolbar   UIToolbar           MARK  Initilization     required init  coder aDecoder  NSCoder            super init coder  aDecoder          self initialize              override init frame  CGRect            super init frame  frame          self initialize                 Sets up the input accessory view with a Done button that closes the keyboard     func initialize                 self keyboardType   UIKeyboardType numberPad          numericKbdToolbar barStyle   UIBarStyle default         let space   UIBarButtonItem barButtonSystemItem  UIBarButtonItem SystemItem flexibleSpace  target  nil  action  nil          let callback    selector NumericTextField finishedEditing          let donebutton   UIBarButtonItem barButtonSystemItem  UIBarButtonItem SystemItem done  target  self  action  callback          numericKbdToolbar setItems  space  donebutton   animated  false          numericKbdToolbar sizeToFit           self inputAccessoryView   numericKbdToolbar               MARK  On Finished Editing Function      objc func finishedEditing                 self resignFirstResponder

Here s the simplest solution I have come across  I have learnt this from Beginning iOS 5 Development book   Assuming the number field is called numberField    In ViewController  add the following method   - IBAction closeKeyboard  id sender   In ViewController m  add the following code   - IBAction closeKeyboard  id sender          numberField resignFirstResponder       Go back to nib file  Open Utilities pan  Open the Identity inspector under Utilities pan  Click on the View  in nib file  once  Make sure you have not clicked on any of the items in the view  For the sake of clarification  you should see UIView under Class in Identity inspector  Change the class from UIView to UIControl  Open Connection Inspector   Click and drag Touch Down and drop the arrow on File Owner icon   FYI    File Owner icon is displayed on the left of View and appears as a hollow cube with yellow frame   Select the method  closeKeyboard  Run the program     Now when you click anywhere on background of View  you should be able to dismiss the keyboard   Hope this helps you solve your problem   -

Below is an overhaul of Luda s answer with the following changes    the accessory view is automatically sized to the width of the application frame the deprecated constant UIBarButtonItemStyleBordered is avoided the  Done  button is instantiated as a UIBarButtonSystemItemDone   Currently the  Done  button is centered in the accessory view  You can position it at left or right by deleting the space on the pertinent side   I have omitted a  Cancel  button because the default keyboard doesn t have one either  If you do want a  Cancel  button  I suggest that you instantiate it as a UIBarButtonSystemItemCancel and that you make sure you re not discarding the original value in your text field  The  Cancel  behavior implemented in Luda s answer  which overwrites the value with a blank string  may not be what you want   -  void viewDidLoad      super viewDidLoad     float appWidth   CGRectGetWidth  UIScreen mainScreen  applicationFrame     UIToolbar  accessoryView     UIToolbar alloc                                initWithFrame CGRectMake 0  0  appWidth  0 1   appWidth      UIBarButtonItem  space     UIBarButtonItem alloc                              initWithBarButtonSystemItem UIBarButtonSystemItemFlexibleSpace                             target nil                             action nil     UIBarButtonItem  done     UIBarButtonItem alloc                             initWithBarButtonSystemItem UIBarButtonSystemItemDone                            target self                            action  selector selectDoneButton      accessoryView items     space  done  space     self valueField inputAccessoryView   accessoryView     -  void selectDoneButton      self valueField resignFirstResponder       For more information about building accessory views  see the Apple documentation on custom views for data input  You will probably want to consult the reference pages on UIToolbar and UIBarButtonItem as well

The solution in UIKeyboardTypeNumberPad and missing return key works great but only if there are no other non-number pad text fields on the screen   I took that code and turned it into an UIViewController that you can simply subclass to make number pads work  You will need to get the icons from the above link   NumberPadViewController h    import  lt UIKit UIKit h gt    interface NumberPadViewController   UIViewController       UIImage  numberPadDoneImageNormal      UIImage  numberPadDoneImageHighlighted      UIButton  numberPadDoneButton      property  nonatomic  retain  UIImage  numberPadDoneImageNormal   property  nonatomic  retain  UIImage  numberPadDoneImageHighlighted   property  nonatomic  retain  UIButton  numberPadDoneButton   -

Another solution  Perfect if there are other non-number pad text fields on the screen     -  void viewDidLoad        super viewDidLoad        UIToolbar  numberToolbar     UIToolbar alloc initWithFrame CGRectMake 0  0  320  50        numberToolbar barStyle   UIBarStyleBlackTranslucent      numberToolbar items       UIBarButtonItem alloc initWithTitle   Cancel  style UIBarButtonItemStyleBordered target self action  selector cancelNumberPad                               UIBarButtonItem alloc initWithBarButtonSystemItem UIBarButtonSystemItemFlexibleSpace target nil action nil                              UIBarButtonItem alloc initWithTitle   Apply  style UIBarButtonItemStyleDone target self action  selector doneWithNumberPad          numberToolbar sizeToFit       numberTextField inputAccessoryView   numberToolbar     - void cancelNumberPad       numberTextField resignFirstResponder       numberTextField text           - void doneWithNumberPad      NSString  numberFromTheKeyboard   numberTextField text       numberTextField resignFirstResponder

I describe one solution for iOS 4 2  here but the dismiss button fades in after the keyboard appears   It s not terrible  but not ideal either   The solution described in the question linked above includes a more elegant illusion to dismiss the button  where I fade and vertically displace the button to provide the appearance that the keypad and the button are dismissing together
