- (void) RetunToSpecificViewController{

   for (UIViewController *controller in self.navigationController.viewControllers)
    {
           if ([controller isKindOfClass:[AnOldViewController class]])
           {
            //Do not forget to import AnOldViewController.h

                       [self.navigationController popToViewController:controller
                                                             animated:YES];
                        break;

Answer 3

Put function in UIViewController 1. it checks if Specific UIViewController exists In UINavigationController then popToViewController or else pushViewController

func navigate(_ navVC: AnyClass, pushVC: UIViewController) {
    for obj in self.navigationController!.viewControllers {
        if obj.isMember(of: navVC) {
            self.navigationController!.popToViewController(obj, animated: true)
            return
        }
    }
    self.navigationController!.pushViewController(pushVC, animated: true)
}

Use

self.navigate(ViewController.self, pushVC: self.storyboard?.instantiateViewController(withIdentifier: "ViewController") as! ViewController)

Quick and safe Swift 3 version:

if let vc = navigationController.viewControllers.filter({ $0 is SpecificViewControllerClass }).first {
  navigationController.popToViewController(vc, animated: true)
}

Answer 5

By Writing the First Line you get the Indexes of all View Controllers and from second Line You will reach up to your Destination.

NSArray *array = [self.navigationController viewControllers];

[self.navigationController popToViewController:[array objectAtIndex:2] animated:YES];

Answer 6

A safer approach:

- (void)turnBackToAnOldViewController{

    for (UIViewController *controller in self.navigationController.viewControllers) {

        //Do not forget to import AnOldViewController.h
        if ([controller isKindOfClass:[AnOldViewController class]]) { 

            [self.navigationController popToViewController:controller
                                                  animated:YES];
            return;
        }
    }
}
