title: iPhone app loading
body: <p>When I load my iPhone app it always loads a black screen first then pops up the main window. This happens even with a simple empty app with a single window loaded. </p>
  
  <p>I've noticed that when loading, most apps zoom in on the main window (or scale it to fit the screen, however you want to think about it) and then load the content of the screen, with no black screen (see the Contacts app for an example).</p>
  
  <p>How do I achieve this effect?</p>
