Ok, so in Objectionable C I could Swizzle my way into replacing the background of a NavigationBar inside a NavigationController (since the NavigationBar is read only, I can't replace it either :-P)..
The technique I used to use can be found here http://sebastiancelis.com/2009/12/21/adding-background-image-uinavigationbar/ What is a MonoTouch appropriate way to place a custom background image in the Navigation Bar of a NavigationController? because swizzling is right out :-P Thanks Josh ________________________________ From: Jason Awbrey [[email protected]] Sent: Thursday, March 15, 2012 11:25 AM To: [email protected] Cc: MonoTouch Forums Subject: Re: [MonoTouch] Now that I can post : Extending the UINavigationController??

Ergo UINavigationController myNavController = new UINavigationController(myfirstViewController); works fine but MyNavViewControllerBase myNavController = new MyNavViewControllerBase(myfirstViewController); just shows a black screen.
