Non-Existent View Controller getting viewDidAppear called?

I'm not sure why this is happening, but I think it would be better to call popToRootViewController:NO on the navigation controller to reset it rather than manually modifying it's viewControllers array.

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.
