[iphone]Handle button click on keyboard

Hi how can i get what but开发者_高级运维ton is clicked on keyboard.I need to have some kind of listener which get what button is clicked on uiKeyboard.

thanks

I finally made it, but i think it is one of the ugliest way, but i share my discovery to you.

1.)i made the viewController uitextviewdelegate , and add text view with 0 height and width

2.)i implement the method

- (void)textViewDidChange:(UITextView *)textView

3.)then i got the value of the last clicked key on keyboard like this

foo = textView.text;
textView.text = @"";

so this is one way but if you know nicer method for this answer my question :)
