I have a fullscreen view (768x1004), when I add a fullscreen subview to this view, it is incorrectly positioned by the height of the status bar (20 pixels). So the view will be clipped by 20 pixels at the top. I can't figure out why this is happening. The only way I can fix it is to set the origin to CGPointMake(0, 20) in viewDidLoad. I...
