title: How do I disable rounded corners for the main view of my entire iPhone app?
body: <p>When running my iPhone app, the app's entire UI has rounded corners (i.e. the area underneath the status bar). The UI is set up using a storyboard, which does not show the rounded corners. How do I turn off the rounded corners? I have tried the following in my <code>AppDelegate's</code> <code>didFinishLoading</code> method:</p>
  
  <pre><code>[self.window.layer setCornerRadius:0.0];
  </code></pre>
  
  <p>but it made no difference. Any ideas?</p>
