iPhone datepicker instead of keyboard?

Question

How would you do that?

I have a form with a UITextField. When I click in it I would like to display a UIDatePicker instead of the default Keyboard that pops-up by de

in .h

UIDatePicker *datePicker;
NSDate *date;
UIToolbar *keyboardToolbar;

in ViewDidLoad:

if (keyboardToolbar == nil) {
    keyboardToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, 44)];
    [keyboardToolbar setBarStyle:UIBarStyleBlackTranslucent];

    UIBarButtonItem *extraSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];

    UIBarButtonItem *accept = [[UIBarButtonItem alloc] initWithTitle:@"Accept" style:UIBarButtonItemStyleDone target:self action:@selector(closeKeyboard:)];

    [keyboardToolbar setItems:[[NSArray alloc] initWithObjects: extraSpace, accept, nil]];
}

self.txtDate.inputAccessoryView = keyboardToolbar;

datePicker = [[UIDatePicker alloc] init];
datePicker.datePickerMode = UIDatePickerModeDate;
[datePicker addTarget:self action:@selector(datePickerValueChanged:) forControlEvents:UIControlEventValueChanged];

self.txtDate.inputView = datePicker;


- (void)datePickerValueChanged:(id)sender{

date = datePicker.date;

NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:@"dd/MM/YYYY"];


[self.txtDate setText:[df stringFromDate:date]];
}

in storyboard add to txtDate -> EditingDidEnd

- (IBAction)establishHour:(id)sender{

hour = hourPicker.date;

NSDateFormatter *hf = [[NSDateFormatter alloc] init];
[hf setDateFormat:@"HH:MM"];

[self.txtHour setText:[hf stringFromDate:hour]];

}

Sets the keyboard as DatePicker and created a toolbar with a button to accept the selection.
