popToViewController的正确使用方法

    

//这里面MyEditingViewController是你想要跳转的界面

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

       if ([controller isKindOfClass:[MyEditingViewControllerclass]]) {

            [self.navigationControllerpopToViewController:controller animated:YES];

        }

    }

//这个是你要跳转到第几个界面

[self.navigationControllerpopToViewController:[self.navigationController.viewControllersobjectAtIndex:2]animated:YES];
