title: How to add UIViewController as target of UIButton action created in programmatically created UIView?
body: <p>I created a <code>UIView</code> programmatically and added a <code>UIButton</code> as it's subview.<br>
  I want a <code>UIViewController</code> to be the target of that button action.<br>
  How would I do that?<br>
  <em>If it was created by Interface Builder then it was easy by using <code>IBAction</code></em>.</p>
