You can be notified of UIDatePicker changes by simply adding a target & action for the control event UIControlEventValueChanged. Check the UIDatePicker reference for more details.

A simple implementation would look something like this:

 [picker addTarget:self 
            action:@selector(datePickerValueChanged:)
  forControlEvents:UIControlEventValueChanged];

and then…

   - (void)datePickerValueChanged:(id)sender{
        UIDatePicker *picker = (UIDatePicker *)sender;
        NSString *dateString;

        dateString = [NSDateFormatter localizedStringFromDate:[picker date]
                                                    dateStyle:NSDateFormatterMediumStyle 
                                                    timeStyle:NSDateFormatterNoStyle];

        [textField setText:dateString];


}
