When a view controller is 'pushed' via GHSidebarNav, it seems that its navigationController is not pushed onto the stack and is not available to be accessed from the view controller (i.e. self.navigationController addSubview:..], etc.

Please provide a detailed description of what you want to happen and the code you expect to work.
