title: accessing view controller's view
body: <p>I am inside a class on a view-based app, one that was creating with one view controller.</p>
  
  <p>WHen I am inside the view controller I can access its view using self.view, but how do I access the same view if I am inside a class?</p>
  
  <pre><code>[[UIApplication sharedApplication] delegate]... //??? what do I put here?
  </code></pre>
  
  <p>thanks</p>
