Can't Set Title of NavigationBar

Question

self.title = @"title";

self.navigationController.title = @"title";

self.navigationItem.title = @"title";

self.navigationController.NavigationItem.title = @"title";

Nothing changes the Title. What can I do?

Answer 1

My Solution was to make in every ViewController it's own NavigationBar and hide the NavitagionBart from the MainTabController.
