Data Entry Form Libraries available for Cocoa Touch?

Does anyone know of any libraries for Objective-C Cocoa Touch that provide data entry fields for all different types of inputs (e.g. Date fields, Boolean, Numbers, Integers, etc). Aside from just the built in text fields that accept all inputs? I know you can limit input in the text field delegate and change the 开发者_开发问答keyboard, but stuff like Date and boolean (yes/no) aren't as slick with that approach.

I'm pretty sure that the UIKit framework has some pretty nice controls for entering dates, booleans, numbers, etc.
