thanks for your feedback Tadeas Kriz.

as with AGPUSH-899, I was in similar dilemma again from constraints of not using external dependencies. So had to either leverage my home-grown solution created some time ago with an action date picker on table view cell but required a UIAlertView with blocks dependency, or use the new mechanism of inline date cells as of iOS 7 which is truly verbose and over-complicated. I imagine an external library can make life easier, but again couldn't use any.

I believe though, and can be wrong, for the purpose of this demo, a placeholder showing the correct format the user what should enter together with the validation strategy implementation is adequate. Further, I believe the different implementation strategies classes (date, number, email, name) implemented together with the mechanism of instantiating them inside the interface builder (something not well documented and requires a blog post but that's another story) is what the user should take away from this demo together with the push-registration API.

Let me know if you think otherwise.
