iOS 从某一界面返回到指定界面

方法一：

- (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:index];
    [self.navigationController popToViewController:viewC animated:YES];
}

方法二：

- (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];
    }
}

方法三：将中间控制器删除

- (void)backToAppointedController3 {
//得到当前视图控制器中的所有控制器
    NSMutableArray *array = [self.navigationController.viewControllers mutableCopy];
    //把B从里面删除
    [array removeObjectAtIndex:1];
    //把删除后的控制器数组再次赋值
    [self.navigationController setViewControllers:[array copy] animated:YES];
}
