Answer 1

You can use the tabbar delegate like this:

func tabBarController(tabBarController: UITabBarController, didSelectViewController viewController: UIViewController) {
    if tabBarController.selectedIndex == 0 {
        let navigationController = viewController as? UINavigationController
        navigationController?.popToRootViewControllerAnimated(true)
    }
}

Answer 2

Use TabBar Delegate method for this

- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController {
    //identify the index of first tab 
    if ([tabBarController selectedIndex] == [[tabBarController viewControllers]count]-1) {
            [(UINavigationController *)self.selectedViewController popToRootViewControllerAnimated:YES];

    }
}
