popToViewController的正確使用方法

    

//這裏面MyEditingViewController是你想要跳轉的界面

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

        if ([controller isKindOfClass:[MyEditingViewController class]]) {

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

        }

    }

//這個是你要跳轉到第幾個界面

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