Custom UIToolbar within UINavigationController's rightBarButtonItem disappears when popping back to view?

If it works in viewDidAppear you could try viewWillAppear. In general, I've never seen a UIToolbar set as a UIBarButtonItem, so I wouldn't necessarily expect standard behavior. Let me know how it goes.

Nope viewWillAppear doesn't work - the custom toolbar is there, but invisible. If I tap where the buttons were displayed, the functionality still works (i.e. The methods still get called).

Apple UI APIs often fail in unusual ways when you try to do anything even slightly unusual (even things that should work), and trying to insert a UIToolbar into a rightBarButtonItem definitely falls into my definition of "unusual". What you really should be doing is hiding the navigation bar and adding the UIToolbar as a subview of your view controller's main view. Alternatively you could avoid UIToolbar completely and implement the buttons yourself in a custom view.

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.
