title: Separator between navigation bar and view - iOS 7
body: <p>In iOS 7 there's a grey separator between the navigation bar and the view.</p>
  
  <p>Back in iOS 6, there wasn't that horizontal line, thus the view would blend in with the navigation bar as if they were the same image. Now I don't know how to remove it...</p>
  
  <p>I've tried resizing the view / navigation bar, but it doesn't help. Any ideas?</p>
