UITabBar and UINavigationController

Let me make the question more clear.

I have tab bar application with navigation controller included in each tab.

When click the tab 2 i go to login screen. From login screen i navigate to next screen (say screen 2) using login button. When i am on screen 2 if i cilck the tab 2 i again go to login screen. I do not want this. I want application to remain at same screen even if tab 2 is clicked again.

If i cilck any other tab in between then it works as expected.

How to achieve this??

- (BOOL)tabBarController:(UITabBarController *)tabBarController 
    shouldSelectViewController:(UIViewController *)viewController {

   if ([tabBarController.selectedViewController isEqual:viewController])
      return NO;
   }
   return YES;
}

Alternatively, you can catch taps on the tab bar and check if the selectedIndex changed or not.

The UITabBarController will pop to the root view controller if you tap a tab that you are currently displaying. To prevent this behavior take a look at this question:

Disable action - user taps on tabbar item to go to root view controller
