Observe the UIKeyboardDidHideNotification notification.

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidHide:) name:UIKeyboardDidHideNotification object:nil];

And...

- (void)keyboardDidHide:(NSNotification *)aNotification {

}

You can also change it to UIKeyboardWillHideNotification if you need to be notified BEFORE the keyboard starts to disappear.

Not sure if it's exactly what you are looking for, but you can try using notifications. Don't have Mac nearby atm, so just copy-pasting the code from github. I have that code in viewDidLoad:

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

and then 2 methods:

- (void)keyboardWillShow:(NSNotification *)notification {

}

- (void)keyboardWillHide:(NSNotification *)notification {

}

Hope it helps

That's not a return key. Return key is the one above it. That's simply a button that dismisses the keyboard and you can't recognize it via standard text input methods. You need to register for UIKeyboardWillHideNotification notification.

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

and implement that method:

- (void)keyboardWillHide:(NSNotification *)notification
{
    // do whatever you want to do when keyboard dismiss button is tapped
}
