BHTKeyboardAnimationBlocks

UIViewController category making life easier when working with animations on keybard appearing/disappearing. Provides a simple block based API to set animations to be performed on each of UIKeyboardNotifications.

Category registers only for those notifications for which there are any blocks set. Registering for notifications happens on viewWillAppear: method call and unregistering on viewDidDisappear: method call.

If view controller is already visible when setting blocks It will automatically register for those notification or unregister from them when assigning nil.
