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

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.
