How to Add "Done" Button to Numpad in iOS Using Swift

How to add Done button to Numpad in iOS using Swift?

As far as I know, you can't add the Done button on the keyboard part; you'd have add a inputAccessoryView to the UITextField or UITextView (if that's what you're using).

Check the documentation for more info.

Edit: Check this question for an example on how to do that.

Edit 2: Similar example in Swift.

Edit 3: Code from edit 2, as link may expire.

override func viewDidLoad()
{
    super.viewDidLoad()

    //--- add UIToolBar on keyboard and Done button on UIToolBar ---//
    self.addDoneButtonOnKeyboard()
}

//--- *** ---//

func addDoneButtonOnKeyboard()
{
    var doneToolbar: UIToolbar = UIToolbar(frame: CGRectMake(0, 0, 320, 50))
    doneToolbar.barStyle = UIBarStyle.BlackTranslucent

    var flexSpace = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil)
    var done: UIBarButtonItem = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Done, target: self, action: Selector("doneButtonAction"))

    var items = NSMutableArray()
    items.addObject(flexSpace)
    items.addObject(done)

    doneToolbar.items = items
    doneToolbar.sizeToFit()

    self.textView.inputAccessoryView = doneToolbar
    self.textField.inputAccessoryView = doneToolbar

}

func doneButtonAction()
{
    self.textViewDescription.resignFirstResponder()
}

Swift 4.2

func addDoneButtonOnKeyboard(){
        let doneToolbar: UIToolbar = UIToolbar(frame: CGRect.init(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 50))
        doneToolbar.barStyle = .default

        let flexSpace = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
        let done: UIBarButtonItem = UIBarButtonItem(title: "Done", style: .done, target: self, action: #selector(self.doneButtonAction))

        let items = [flexSpace, done]
        doneToolbar.items = items
        doneToolbar.sizeToFit()

        txtMobileNumber.inputAccessoryView = doneToolbar
    }

    @objc func doneButtonAction(){
        txtMobileNumber.resignFirstResponder()
    }

How to add Done button on numberpad keyboard for VPMOTPView in swift

First introduce this extension on UITextField to add Done button.

extension UITextField {

    /// Adding a done button on the keyboard
    func addDoneButtonOnKeyboard() {
        let doneToolbar = UIToolbar(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 50))
        doneToolbar.barStyle = .default

        let flexSpace = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
        let done = UIBarButtonItem(title: "Done", style: .done, target: self, action: #selector(self.doneButtonAction))

        let items = [flexSpace, done]
        doneToolbar.items = items
        doneToolbar.sizeToFit()

        self.inputAccessoryView = doneToolbar
    }

    /// Done button callback
    @objc func doneButtonAction() {
        self.resignFirstResponder()
    }
}

Now, call the addDoneButtonOnKeyboard method on all the UITextField instances used in the VPMOTPView as below,

override func viewDidLoad() {
    super.viewDidLoad()
    //self.navigationBarButton()
    otpView.otpFieldsCount = 6
    otpView.otpFieldDefaultBorderColor = UIColor.lightGray
    otpView.otpFieldEnteredBorderColor = UIColor(named: "LightPrimaryColor") ?? UIColor.blue
    otpView.otpFieldErrorBorderColor = UIColor.red
    otpView.otpFieldBorderWidth = 1
    otpView.delegate = self
    otpView.shouldAllowIntermediateEditing = false
    otpView.otpFieldSize = 25
    otpView.otpFieldDisplayType = .underlinedBottom
    otpView.otpFieldEntrySecureType=false
    otpView.initializeUI()
    emailIconLabel.text = "We have sent an sms with OTP \nto \(phone!)"

    otpView.subviews.compactMap({ $0 as? VPMOTPTextField}).forEach { tv in
        tv.addDoneButtonOnKeyboard()
    }
    self.getOTPService()
}

How to do number keypad with done button in Swift 2.0?

You can add done button above keyboard using toolbar

override func viewDidLoad() {
    super.viewDidLoad()
    let tooBar: UIToolbar = UIToolbar()
    tooBar.barStyle = UIBarStyle.BlackTranslucent
    tooBar.items=[
        UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: self, action: nil),
        UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Done, target: self, action: "donePressed")]
    tooBar.sizeToFit()
    yourTextFeild.inputAccessoryView = tooBar
}

func donePressed () {
    yourTextFeild.resignFirstResponder()
}

It will look like this

How to add a 'Done' button to numpad keyboard in iOS

This is a simple way of projecting a done button in iOS7 num-keypad. In the below delegate method of UITextField, add a notification for keyboard show.

-(void)textFieldDidBeginEditing:(UITextField *)textField {
    
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(keyboardWillShow:)
                                                 name:UIKeyboardWillShowNotification
                                               object:nil];
}

Now implement the method keyboardWillShow as below. Here we need to take extra care for iOS7.

- (void)keyboardWillShow:(NSNotification *)note {
    // create custom button
    UIButton *doneButton = [UIButton buttonWithType:UIButtonTypeCustom];
    doneButton.frame = CGRectMake(0, 163, 106, 53);
    doneButton.adjustsImageWhenHighlighted = NO;
    [doneButton setImage:[UIImage imageNamed:@"doneButtonNormal.png"] forState:UIControlStateNormal];
    [doneButton setImage:[UIImage imageNamed:@"doneButtonPressed.png"] forState:UIControlStateHighlighted];
    [doneButton addTarget:self action:@selector(doneButton:) forControlEvents:UIControlEventTouchUpInside];
    
    if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")) {
        dispatch_async(dispatch_get_main_queue(), ^{
            UIView *keyboardView = [[[[[UIApplication sharedApplication] windows] lastObject] subviews] firstObject];
            [doneButton setFrame:CGRectMake(0, keyboardView.frame.size.height - 53, 106, 53)];
            [keyboardView addSubview:doneButton];
            [keyboardView bringSubviewToFront:doneButton];
            
            [UIView animateWithDuration:[[note.userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] floatValue]-.02
                                  delay:.0
                                options:[[note.userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] intValue]
                             animations:^{
                                 self.view.frame = CGRectOffset(self.view.frame, 0, 0);
                             } completion:nil];
        });
    } else {
        // locate keyboard view
        dispatch_async(dispatch_get_main_queue(), ^{
            UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
            UIView* keyboard;
            for(int i=0; i<[tempWindow.subviews count]; i++) {
                keyboard = [tempWindow.subviews objectAtIndex:i];
                // keyboard view found; add the custom button to it
                if([[keyboard description] hasPrefix:@"UIKeyboard"] == YES)
                    [keyboard addSubview:doneButton];
            }
        });
    }
}

Now add this macro to suitable header to detect the SYSTEM_VERSION

#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)

How can I show done button on the decimal pad keyboard?

Firstly, create a new Swift File. Add this to the file :

import Foundation
import UIKit

extension UIViewController{
    func toolBar() -> UIToolbar{
        let toolBar = UIToolbar()
        toolBar.barStyle = .default
        toolBar.isTranslucent = true
        toolBar.barTintColor = UIColor.init(red: 0/255, green: 25/255, blue: 61/255, alpha: 1) //Write what you want for color
        let space = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
        var buttonTitle = "Done" //Or "Tamam"
        var cancelButtonTitle = "Cancel" //Or "İptal" for Turkish
        let doneButton = UIBarButtonItem(title: buttonTitle, style: .done, target: self, action: #selector(onClickDoneButton))
        let cancelButton = UIBarButtonItem(title: cancelButtonTitle, style: .plain, target: self, action: #selector(onClickCancelButton))
        doneButton.tintColor = .white
        cancelButton.tintColor = .white
        toolBar.setItems([cancelButton, space, doneButton], animated: false)
        toolBar.isUserInteractionEnabled = true
        toolBar.sizeToFit()
        return toolBar
    }

    @objc func onClickDoneButton(){
        view.endEditing(true)
    }

    @objc func onClickCancelButton(){
        view.endEditing(true)
    }
}

And add this toolbar to your textfield :

yourTextField.inputAccessoryView = toolBar()

Hope it helps...

Done button in phone pad (Swift 4)

Replace

Selector(("doneButtonAction"))

with

#selector(ViewController.doneButtonAction)

And complete code will be:

let done: UIBarButtonItem = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.done, target: self, action: #selector(ViewController.doneButtonAction))

And add @objc before your doneButtonAction method and final code will be:

@objc func doneButtonAction()
{
    self.registerTF[5].resignFirstResponder()
}

How to show Done button on iOS number pad keyboard?

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];
}
