Question

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

Answer 1

I'm not sure what you want to accomplish, but maybe this can help you: Register with NSNotificationCenter to receive the UIKeyboardWillHideNotification and/or UIKeyboardDidHideNotification.

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

...

- (void) myKeyboardWillHideHandler:(NSNotification *)notification {
    NSLog(@"Keyboard wants to hide. What a coward.");
}

Answer 2

put this to viewDidLoad

// register to track event when user presses hide keyboard button on bottom right cornor for iPAD
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(textFieldShouldReturn:) name:UIKeyboardWillHideNotification object:nil];

and this will make your - (BOOL)textFieldShouldReturn:(UITextField *)textField; delegate method to get called when keyboard down button is pressed in iPAD.
