Disable numbers and punctuation button on iphone keyboard

I have a UITextField that brings开发者_StackOverflow中文版 up the keyboard. I just want the user to input alphabets and not numbers or punctuation marks. How do I disable the numbers and punctuation key on the default keyboard that pops up.

Thanks.

 Looking like you used the Default Keyboard....instead you can try to use:

 yourTextField.keyboardType = UIKeyboardTypeAlphabet;  This might solve your problem.

& if this doesn't solve your problem other way, is:

----> You need to create the Custom Keypad as per your requirement.
