    Implement

    -(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string

    in the delegate, and check that all characters in string are of the kind that you allow.

    One very simple way of checking characters for membership in a set is by using NSCharacterSet class.
