ios提供的navigation条状方法一共有三种
1. - (nullable UIViewController *)popViewControllerAnimated:(BOOL)animated;
2. - (nullable NSArray<__kindof UIViewController *> *)popToViewController:(UIViewController *)viewController
animated:(BOOL)animated;
3. - (nullable NSArray<__kindof UIViewController *> *)popToRootViewControllerAnimated:(BOOL)animated;
常用的如下：
[self.navigationControllerpopToViewController：[self.navigationController.viewControllersobjectAtIndex:2]animated:YES];
for(UIViewController*temp inself.navigationController.viewControllers) {
if([tempisKindOfClass:[你要跳转到的Controllerclass]]) {
[self.navigationControllerpopToViewController:tempanimated:YES];
}
}
