Question

I got a tabbar application.

There is only 2 tabs in the tabbar. First tab is a NavigationController, there are two views in the NavigationController – root and detail views, second is a TableViewController. Second works perfect, but the the first doesn’t.

I start in first view (NavigationController). Then go in this NavigationView to the detail view. Then, for example, i go to the second tabbar view. Then go back to the first, but i dont see the root view, but the detail view.

How can i open the root view every time?

Answer 1

Use the UITabBarController delegate method tabBarController:didSelectViewController: like this:

- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController {
  if (viewController != tabBarItemForNavControllerTab) {
    [self.navControllerInFirstTab popToRootViewControllerAnimated:NO];
  }
}

Also make sure that delegate is setup properly, when creating your UITabBarController and you change the code from my snippet to fit your controller names.
