Tried setting break points into viewDidLoad, viewDidUnload, viewWillAppear, viewWillDisappear, viewDidDisappear, becomeFirstResponder and resignFirstResponder. Nothing. None of those are called, when I set hidden = ...
I'm a newbie. I can't figure out how and where to call ResignFirstResponder to get rid of the keyboard when the user finished entering the text in an UITextField.
