Detect if UIViewController is running inside an existing UINavigationController?

You could use self. NavigationController for that purpose. It will return nil or the navigationController.

Thanks, I wasn't sure that would be a reliable way. But luckily it's that simple :) – Ivo Jansch Aug 22 at 20:59.

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.
