Answer 1

That is the expected behaviour if you are using the tab bar controller and the navigation controller in the item of the tab bar. User will expect the tab to retain the state of the view.

If you still want to enforce the app to go back to the root view controller of the navigation controller when user goes back to the tab, you can implement the UITabBarControllerDelegate tabBarController:didSelectViewController: method. What this delegate method does is:

Tells the delegate that the user selected an item in the tab bar.

Then call the method of UINavigationController called popToRootViewControllerAnimated: when user tap on the tab. This will help you to:

Pops all the view controllers on the stack except the root view controller and updates the display.

For example:

- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController
{
    if(viewController == yourNavigationController) {
        UINavigationController *navigationController = (UINavigationController *)viewController;
        [navigationController popToRootViewControllerAnimated:NO];
    }
}
