iphone - UIKeyboardTypeNumberPad without a done button

Question

How can we implement UIKeyboardTypeNumberPad so that it will have a 'done' button? By default it does not have one.

If I am not wrong then You want to ask as to how to add a custom "Done" button to keyboard for UIKeyboardTypeNumberPad . In that case this might be helpful. Declare a UIButton *doneButton in.h and add the following code to .m file

- (void)addButtonToKeyboard {
    // create custom button
    if (doneButton == nil) {
        doneButton  = [[UIButton alloc] initWithFrame:CGRectMake(0, 163, 106, 53)];
    }
    else {
        [doneButton setHidden:NO];
    }

    [doneButton addTarget:self action:@selector(doneButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
    // locate keyboard view
    UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
    UIView* keyboard = nil;
    for(int i=0; i<[tempWindow.subviews count]; i++) {
        keyboard = [tempWindow.subviews objectAtIndex:i];
        // keyboard found, add the button
        if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 3.2) {
            if([[keyboard description] hasPrefix:@"<UIPeripheralHost"] == YES)
                [keyboard addSubview:doneButton];
        } else {
            if([[keyboard description] hasPrefix:@"<UIKeyboard"] == YES)
                [keyboard addSubview:doneButton];
        }
    }
}

- (void)doneButtonClicked:(id)Sender {
//Write your code whatever you want to do on done button tap
//Removing keyboard or something else
}

I am using the same in my application and the button's frame are thus adjusted, You can thus call [self addButtonToKeyboard ] whenever you need to show up the done button over the keyboard. UIKeyboardTypeNumberPad has no Done button otherwise.
