iOS View with a flipside, add navigation bar?

[nottooshabby]

I have a view A and a flipside view B that are controlled by a rootviewcontroller. This works fine. Does anybody have an example of how I could put a nav bar on view A so that I could have another view, view C that is activated from a button on the upper right on a navigation bar? I'm confused if I should put this in view A's controller of the root view controller.
