title: Add Selector to UIButton
body: <p>I have  <code>ViewController</code> and then two different <code>ViewControllers</code> that extend that main <code>ViewController</code>, one for the iPhone and the other for the iPad.</p>
  
  <p>The iPad's <code>ViewController</code> instantiates a separate extended <code>UIView</code> and sets it as its own view. That view has some buttons, which I want to add its selector methods as some methods in the main <code>ViewController</code>. How can this be achieved?</p>
  
  <p>So here's a way to visualize this:</p>
  
  <pre><code>Main ViewController
  | iPhone ViewController
  | iPad ViewController
    | Some UIView Class    --&gt; Button must invoke method in Main View Controller
  </code></pre>
  
  <p><strong>EDIT:</strong>
  I do not use interface builder at all.</p>
