How to add a subview to a UINavigation Controller without losing navigation bar?

Don't make detailViewController a subclass of UIView, instead go with UIViewController. So your splitView array will contain a instance of UINavigationController (rootVC) and other of UIViewController (detailVC).

To fix this I added a UINavigationController to my helper UIView, and added a UIButtonBarItem to call the popover for selecting a new item in the master view. It seems really simple in retrospect. The only tricky bit will be making the UIButtonBarItem hide when in landscape.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
