NavigationItem not displayed in contentcontroller when using storyboard

My project uses the storyboard to create screens, along with NavigationControllers. Everything works fine except the NavigationItem is not displayed in the ContentController....I think I might be missing something really obvious, or do the NavigationControllers get stomped on in the SideBar constructor?

What i'm trying to do is recreate your example where you have a contentcontroller with a navigationbar that slides across to make way for the menucontroller, but I cannot figure out where/how to add the navigationitem to the contentcontroller. If I add it to the rootcontroller the the navigationbar does not move when the menu sldies across
