Yes, though not all of its functionality. > When the docs say that a UINavigationController can be a tab in a tab bar > interface, they mean a UITabBarController, not a UIViewController that > happens to implement a tab bar interface.

I am hoping that those problems are not going to appear in this particular app (after all, I'm not using all the power built into tab bars and tab bar controllers) or, if they do, as with the status bar gap appearing when the device is turned upside down, then I'm hoping the client will reconsider their requirements. I'm sure I'm not the first nor will I be the last developer to bend the rules a little in order to satisfy one's clients. >> In order to accomplish that, I need to be able to change the tab bar's >> delegate and list of items and restore them when the navigation controller >> returns to its root view.

I admit that I hadn't considered your suggestion, and it might satisfy the needs of everyone involved.
