detect iPad keyboard Hiding button

Question

Hi is there any way to detect iPad keyboard hiding button ? i mean when user press this button :

Answer 1

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(textFieldShouldReturn:) name:UIKeyboardWillHideNotification object:nil];

This actually crashes on the go.

But if you call a custom method, like: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(myCustomeMethodToResignTextFieldResponder) name:UIKeyboardWillHideNotification object:nil];

Then it will work just fine.. :-)
