title: Change dynamic height of a uitextview above uikeyboard using DAKeyboardControl
body: <p>in my project I'm using this project:</p>
  
  <p><code>DAKeyboardControl</code> : <a href="https://github.com/danielamitay/DAKeyboardControl" rel="nofollow">https://github.com/danielamitay/DAKeyboardControl</a></p>
  
  <p>To attach a <code>UIToolbar</code> with a <code>UITextView</code> above the keyboard and move it when dismiss the keyboard with panning gesture, now i can't understand how I can change the height of the <code>UITextView</code> and <code>UIToolbar</code> when I'm editing text, to add the <code>UITextView</code> I use the same code of the <code>DAKeyboardControl</code> example and I change <code>UITextField</code> with <code>UITextView</code>.</p>
  
  <p>Now how I can change text view height dynamically?</p>
