title: How to handle UIApplicationDelegate methods in an UIViewController?
body: <p>I have a UIViewController on a tab of a tab based app, that hooks up UIApplicationDelegate. I'd like to handle app events by UIApplicationDelegate, but I don't get them in my UIViewController, its methods are not called.</p>
  
  <p>What should I do beside hook up it in my UIViewController's interface declaration?</p>
  
  <pre><code>@interface TestViewController : UIViewController&lt;UIApplicationDelegate&gt;
  @end
  </code></pre>
  
  <p>Other delegates are works, I can handle them, except this, UIApplication and its delegate should have some trivial 'trick', but I could not find.</p>
  
  <p>Thanks!</p>
