Prevent UINavigationController from popping on double tap of UITabBarController

Question

I have a UITabBarController in the root of my storyboard with three tabs. One of the tab is used to display the user information. I have set this tab to transition to the register/login page if the user has not registered. But the ViewController gets popped(and corrupts the Navigation Bar ) when I double tap the tab icon. I cannot use the modal transition as it hides the TabBarController . What is the best solution to solve this issue?

You can use 'shouldSelectViewController' delegate of TabViewConroller to check if the selected viewController is same as the clicked one and skip it accordingly.

- (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController {
       if(viewController == tabBarController.selectedViewController)
       {
            return NO;
       }
  }
