- Add finished implementation of BKBirthdayField for (MM/DD/YYYY) format
- Updated example app with BKBirthdayField and associated label
- Sample app will say "Invalid for non-leap year" if you type in month (2) and day (29) for years that are not a leap year.
- Added UITapGestureRecognizer so you can see associated label for BKBirthdayField (UIScrollView probably better, but code to account for keyboard is distracting from purpose of demo).

How about using NSCalendar for this validation check?
Please refer to below URL. You can get last date of month by using NSCalendar.

Hello @bkook:
Problem with trying to use NSDateComponents is that with the MM / DD / YYYY format, the year hasn't been typed in yet so I can't use NSDateComponents to do the actual calculations. And generally it would work, except for leap months.
I also feel weird instantiating NSDate objects and using NSCalendar to do pretty heavy math when the current solution gets the correct date in just 3 operations (1 switch and 2 integer comparisons).
I'll move that code to a separate method so it reads cleaner.
