Sticky header's position is not right on iOS 7

[RobotAmiee]

Hi I put collection view in a navigation controller' root view controller and set header sticky, When I scroll up the collection view, the header goes to the top of collection view and would be hidden by the navigation bar. Even if I set the collection view's content insets, the header will always be hidden by the navigation bar.

This isn't a bug with @frogermcs code. You need to look at: self.automaticallyAdjustsScrollViewInsets = YES;
