title: How do I programmatically set the Return Key for a particular UITextField?
body: <p>I can't believe that this question hasn't been asked yet, but I have been unable to find it so that is my assumption.</p>
  
  <p>I have created custom <code>UITableViewCel</code>l subclasses using Interface Builder. These each contain a <code>UILabel</code> and a <code>UITextField</code> and are used for our login screen.</p>
  
  <p>On the first <code>UITextField</code>, I want the Keyboard Key to say <code>Next</code>. However, on the second <code>UITextField</code>, I want it to say "Done."</p>
  
  <p>How do I programmatically change the value of the <code>Return Key</code> on the keyboard? I cannot use <code>Interface Builder</code>, since that would make both keys appear as <code>Done</code>.</p>
  
  <p>Thanks!</p>
