title: Dismiss keyboard on UITextField using Interface Builder
body: <p>I've seen this, but don't remember what Jedi technique exactly was used through interface builder to dismiss uikeboard when return key is pressed. Anyone knows how to do this?</p>
  
  <p>Please do not post about using UITextFieldDelegate, I know that method, I'm only interested in forcing keyboard to be dismissed on return key being hit without any additional logic or protocol conformation.</p>
