title: iPad 'dismiss keyboard' button doesn't dismiss keyboard
body: <p>I have a UITextField in a Landscape view, and when I press the 'dismiss keyboard' button in the lower right of the UIKeyboard view, the keyboard does NOT disappear. Is there a way to programmatically listen for when this key was pressed? Or is there a connection I am not seeing that will make this keyboard go away?
  This is iOS 4 and XCode 4. Thanks.</p>
