Basically, the reason for the "freeze" when you click on your UITextField with itself as a delegate is that respondsToSelector is calling itself -> infinite recursion.

UITextField is unique AFAIK. You can usually use a class as its own delegate with no particular problems. For UITextField you must create an actual delegate (that could, of course, call methods on the UITextField for which it's a delegate. Just be careful to avoid retain loops, even if you're using ARC).
