title: How to get the applicationFrame minus the height of the UINavigationBar?
body: <p>I put this in loadView and it works:</p>
  
  <pre><code>CGRect navFrame = [[UIScreen mainScreen] applicationFrame];
  navFrame.size.height -= self.navigationController.navigationBar.frame.size.height;
  UIImageView *imageView = [[UIImageView alloc] initWithFrame:navFrame];
  </code></pre>
  
  <p>But is there a variable like applicationFrame that gives the applicationFrame minus the UINavigationBar height?</p>
