Answer 1

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.
