iPhone- How to get the main view (1st view) every time when we switching form one tab to another tab

In my iPhone app, I have used tabbarcontroller in that i have 4 tabs for four different items

In each tab i have different views navigate transaction in those.

my requirement is, when i switch form on tab to another tab by taping on tabbar item.

T*the main view (first view ) of each tab has to be appeared instead of currently working view.*

For ex:

  1. I select tab 3 there i do some operations and navigate to some 2nd view in the third tab.

  2. and then i secet tab 4 and then again tab3.. then the previously woriking view view 2 presents in tab3,

    1. But i need to present 1st view at any time when i select tab 3 (Same like in any other tabs)

how to do..

Make a subclass of UINavigationController, change the class of any navigation controllers you have in your storyboard to that class, and put this code in that subclass:

-(void)viewDidDisappear:(BOOL)animated {
    [self popToRootViewControllerAnimated:NO];
}

Whenever you click on another tab, this method will be called, and it will reset the navigation stack back to the root view controller.

Set your view controller or appdelegate as delegate of your tabbarcontroller. implement this delegate function 

- (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController{
  int selectedIndex = tabBarController.selectedIndex;
  NSArray *tabbarControllers = tabBarController.viewControllers;

  //Then replace tabbarControllers[selectedIndex] by your new view controller(with navigation controller) 

   tabBarController.viewControllers = Your replaced Array;
}
