Question

I am building an iPhone application that requires the user to enter his credentials in order to use the application and can sign out in any moment.

I have used UITabBarController to navigate through my views, now I need to add a Logout button in a way that it is available/visible all the time.

Can anybody suggest a solution or best practice for this case?

Answer 1

Can you spare a tab bar item for that? It seems like the most clean way. Then you can use

  tabBarController:didSelectViewController: 

method of the UITabBarControllerDelegate.

something like this (assuming that the logout tab is the 5th tab)

- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController {

    if ([tabBarController selectedIndex] == 4) {

        //LOGOUT
    }
}
