there is, you need to use a formatter for that, you can even set the allowed
characters to be inputted to the textfield.
check NSFormatter if it is of any help, you can also extend the class to adjust
to your needs.

Subject: Re: Setting a delegate on a UITextField
Okay, part II:
Is there a way to allow only a certain number of characters in a UITextField?
Should this be done in the -textFieldDidEndEditing delegate callback, with an
alert to the user, or just truncating the field, or ...?
