title: UIKeyBoard Return Button UIReturnKeyDone
body: <pre><code>textfield.returnKeyTYpe = UIReturnKeyDone
  </code></pre>
  
  <p>So the above makes my Return button on the keyboard to say Done. I have seen Apps with Blue color button on the UIKeyBoard. Is that simple enough to do? How do I change the background color of the Return key? </p>
