How to show “Done” button on iPhone number pad


How to show “Done” button on iPhone number pad



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?

How to create nested array or multidimensional array
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() }

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..

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 <UIKit/UIKit.h>  @interface NumberPadViewController : UIViewController {     UIImage *numberPadDoneImageNormal;     UIImage *numberPadDoneImageHighlighted;     UIButton *numberPadDoneButton; }  @property (nonatomic, retain) UIImage *numberPadDoneImageNormal; @property (nonatomic, retain) UIImage *numberPadDoneImageHighlighted; @property (nonatomic, retain) UIButton *numberPadDoneButton;  - (IBAction)numberPadDoneButton:(id)sender;  @end 
and NumberPadViewController.m:.
#import "NumberPadViewController.h"  @implementation NumberPadViewController  @synthesize numberPadDoneImageNormal; @synthesize numberPadDoneImageHighlighted; @synthesize numberPadDoneButton;  - (id)initWithNibName:(NSString *)nibName bundle:(NSBundle *)nibBundle {     if ([super initWithNibName:nibName bundle:nibBundle] == nil)         return nil;     if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 3.0) {         self.numberPadDoneImageNormal = [UIImage imageNamed:@"DoneUp3.png"];         self.numberPadDoneImageHighlighted = [UIImage imageNamed:@"DoneDown3.png"];     } else {                 self.numberPadDoneImageNormal = [UIImage imageNamed:@"DoneUp.png"];         self.numberPadDoneImageHighlighted = [UIImage imageNamed:@"DoneDown.png"];     }             return self; }  - (void)viewWillAppear:(BOOL)animated {     [super viewWillAppear:animated];      // Add listener for keyboard display events     if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 3.2) {         [[NSNotificationCenter defaultCenter] addObserver:self                                                      selector:@selector(keyboardDidShow:)                                                       name:UIKeyboardDidShowNotification                                                     object:nil];          } else {         [[NSNotificationCenter defaultCenter] addObserver:self                                                   selector:@selector(keyboardWillShow:)                                                       name:UIKeyboardWillShowNotification                                                     object:nil];     }      // Add listener for all text fields starting to be edited     [[NSNotificationCenter defaultCenter] addObserver:self                                               selector:@selector(textFieldDidBeginEditing:)                                                  name:UITextFieldTextDidBeginEditingNotification                                                 object:nil]; }  - (void)viewWillDisappear:(BOOL)animated {     if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 3.2) {         [[NSNotificationCenter defaultCenter] removeObserver:self                                                          name:UIKeyboardDidShowNotification                                                        object:nil];           } else {         [[NSNotificationCenter defaultCenter] removeObserver:self                                                          name:UIKeyboardWillShowNotification                                                        object:nil];     }     [[NSNotificationCenter defaultCenter] removeObserver:self                                                      name:UITextFieldTextDidBeginEditingNotification                                                    object:nil];     [super viewWillDisappear:animated]; }  - (UIView *)findFirstResponderUnder:(UIView *)root {     if (root.isFirstResponder)         return root;         for (UIView *subView in root.subviews) {         UIView *firstResponder = [self findFirstResponderUnder:subView];                 if (firstResponder != nil)             return firstResponder;     }     return nil; }  - (UITextField *)findFirstResponderTextField {     UIResponder *firstResponder = [self findFirstResponderUnder:[self.view window]];     if (![firstResponder isKindOfClass:[UITextField class]])         return nil;     return (UITextField *)firstResponder; }  - (void)updateKeyboardButtonFor:(UITextField *)textField {      // Remove any previous button     [self.numberPadDoneButton removeFromSuperview];     self.numberPadDoneButton = nil;      // Does the text field use a number pad?

Here is the most recent code.

Simply include #import "UIViewController+NumPadReturn.h" in your viewController.

. Here is the .h.

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..

This forum post describes how to customize the UIKeyboard to add your custom view onto the keyboard..


9:


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..


10:


The simplest way is:

Create custom transparent button and place it in left down corner, which will have same CGSize as empty space in UIKeyboardTypeNumberPad.

Toggle (show / hide) this button on textField becomeFirstResponder, on button click respectively..


11:


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..
  1. In ViewController, add the following method:.
    -(IBAction)closeKeyboard:(id)sender; 
  2. In ViewController.m, add the following code:.
    -(IBAction)closeKeyboard:(id)sender {       [numberField resignFirstResponder];  } 
  3. Go back to nib file..
  4. Open Utilities pan.
  5. Open the Identity inspector under Utilities pan.
  6. 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.
  7. Change the class from UIView to UIControl.
  8. Open Connection Inspector.

  9. 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.)
  10. Select the method: closeKeyboard.
  11. 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.

:-).

I modified Bryan's solution to be a little more robust, so that it would play nicely with other types of keyboards that could appear in the same view.

It's described here:. Create a DONE button on the iOS numpad UIKeyboard. I'd try to explain it here, but most of it is code to look at that wouldn't easily fit here.


13:


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..


14:


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..

For Swift 2.2 I use this.
func addDoneButtonOnKeyboard() {     let doneToolbar: UIToolbar = UIToolbar(frame: CGRectMake(0, 0, self.view.bounds.size.width, 50))      let flexSpace = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil)     let done: UIBarButtonItem = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Done, target: self, action: #selector(DetailViewController.finishDecimalKeypad))      var items: [UIBarButtonItem]? = [UIBarButtonItem]()     items?.append(flexSpace)     items?.append(done)      doneToolbar.items = items     doneToolbar.sizeToFit()     self.productPrice.inputAccessoryView=doneToolbar }  func finishDecimalKeypad() {     self.productPrice?.resignFirstResponder() } 


16:


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.


17:


Swift 2.2 / I used Dx_'s answer.

However, I wanted this functionality on all keyboards.

So in my base class I put the code:.
func addDoneButtonForTextFields(views: [UIView]) {     for view in views {         if let textField = view as? UITextField {             let doneToolbar = UIToolbar(frame: CGRectMake(0, 0, self.view.bounds.size.width, 50))              let flexSpace = UIBarButtonItem(barButtonSystemItem: .FlexibleSpace, target: nil, action: nil)             let done = UIBarButtonItem(title: "Done", style: .Done, target: self, action: #selector(dismissKeyboard))              var items = [UIBarButtonItem]()             items.append(flexSpace)             items.append(done)              doneToolbar.items = items             doneToolbar.sizeToFit()              textField.inputAccessoryView = doneToolbar         } else {             addDoneButtonForTextFields(view.subviews)         }     } }  func dismissKeyboard() {     dismissKeyboardForTextFields(self.view.subviews) }  func dismissKeyboardForTextFields(views: [UIView]) {     for view in views {         if let textField = view as? UITextField {             textField.resignFirstResponder()         } else {             dismissKeyboardForTextFields(view.subviews)         }     } } 
Then just call addDoneButtonForTextFields on self.view.subviews in viewDidLoad (or willDisplayCell if using a table view) to add the Done button to all keyboards..

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()     } }
