iOS 从某一界面返回到指定界面

- (void)backToAppointedController1 {

//    直接查找你需要跳转的界面 不会算的话自己从1开始试吧 、此法需要知道你返回到的控制器的位置

    UIViewController *viewC = [self.navigationController.viewControllers objectAtIndex:2];

    [self.navigationController popToViewController:viewC animated:YES];

}

---

- (void)backToAppointedController2 {

//  此法只需要知道你需要返回的控制器的类名称即可

    UINavigationController *navC = self.navigationController;

    NSMutableArray *viewControllers = [[NSMutableArray alloc] init];

    for (UIViewController *vc in navC.viewControllers) {

        [viewControllers addObject:vc];

        if ([vc isKindOfClass:[YourController Class]]) {

            break;

        }

    }

    if (viewControllers.count == navC.viewControllers.count) {

            [self.navigationController popViewControllerAnimated:YES];

    }

    else {

        [navC setViewControllers:viewControllers animated:YES];

    }
