(in ViewDidLoad)

//setup the datePicker input
    UIDatePicker * datePicker = [[UIDatePicker alloc] init] ;
    datePicker.datePickerMode = UIDatePickerModeDate;
    datePicker.date = [NSDate date];
    self.expirationDateText.inputView = datePicker;

    //retain a copy of the date picker if needed
    self.expirationDatePicker = datePicker;

    //add a call back to update the text field when the date picker changes
    [datePicker addTarget:self action:@selector(dateChanged:) forControlEvents:UIControlEventValueChanged];

    //add a recogizer to hide the keyboard when tapping the screen
    [self.view addGestureRecognizer:[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(hideKeyboard:)]];

and if you want to add a toolbar with a done button… just add this!

self.expirationDateText.inputAccessoryView = [self getKeyboardAccessoryWithTitle:@“Done" andSelector:@selector(hideKeyboard)];

-(UIToolbar*)getKeyboardAccessoryWithTitle:(NSString*)title andSelector:(SEL)selector
{
    UIToolbar* numberToolbar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];
    numberToolbar.barStyle = UIBarStyleBlackTranslucent;
    numberToolbar.items = [NSArray arrayWithObjects:
                           //[[UIBarButtonItem alloc]initWithTitle:@"Cancel" style:UIBarButtonItemStyleBordered target:self action:@selector(cancelNumberPad)],
                           [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil],
                           [[UIBarButtonItem alloc]initWithTitle:title style:UIBarButtonItemStyleDone target:self action:selector],
                           nil];
    [numberToolbar sizeToFit];
    return numberToolbar;
}
