I'm using storyboard for the UI and I have the following: 

A login window which is the init view of the segue. If the login is succesfull it will take the user to another view which can't have the back button to the login page! This is a `UITabBarController` and it has its own navigation bar. Now it shows both navigation bars and the back button is present the whole app. 

If I tap the back button it always takes me to the login view. Any ideas?
