setkeyboardtype in CCTextField in iOS

Hello.

I’m trying to change the keyboard that my app shows when I touch a CCTextField component: numeric, alphanumeric,etc… I have seen that there is a method in UITextField called setKeyboardType, but I haven’t seen anything similar in CCTextField.
I guess that CCTextField is using UITextField in iOS, but I don’t know how…
Does anybody have any idea?

Thanks!

You can refer to CCEditBox.
