title: get UIView's viewcontroller (iphone)
body: <p>I've done this to get the view:</p>
  
  <pre><code>[self.superview viewWithTag:10]
  </code></pre>
  
  <p>But how can I get that view's viewcontroller. Just like you can get the the viewcontroller's view I want to go the other way so I can send a message (call a method) to that viewcontroller. eg:</p>
  
  <pre><code>[[self.superview viewWithTag:10].viewController doSomething];
  </code></pre>
  
  <p>(obviously that not actual code but I want something like that)</p>
