title: Notification for change of iPad keyboard height
body: <p>I am trying to show a UITextField on top of the iPad keyboard.</p>
  
  <p>I was able to get the height of the keyboard when it was presented with the notification.</p>
  
  <p>However, in iPad, by change the language input of the keyboard -> most likely to Japanese, the height of the keyboard changed because a text-hypothesis area was shown on top of the keyboard, that caused my UITextfield hidden by that area....</p>
  
  <p>Does anybody know how can I get the height changed notification or any other way?</p>
