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?


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;

    [numberTextField resignFirstResponder];
    numberTextField.text = @"";

    NSString *numberFromTheKeyboard = numberTextField.text;
    [numberTextField resignFirstResponder];
