I’m very curious – why does UITextInputDelegate have all its methods required? Why can’t I just implement the one I want (for example textDidChange)?
It might be a performance thing. These methods are called frequently and it’s quite a big performance hit to have to send
-respondsToSelector:every time anything changes.
