title: Sharing a common background image in a UINavigationController hierarchy?
body: <p>I know it's possible to set a background image for the UINavigationBar, but I would like to know if there is a way to share a common background view for all controllers in a UINavigationController. The idea is to have a UIImageView as the background that stays in place rather than "sliding" over itself when navigating to a new controller.</p>
