iOS --popToViewController -- 跳转界面

问题：

nav 从a-b-c-d

在d 的界面想直接回到a

如下

[self.navigationController popToViewController:[self.navigationController.viewControllers objectAtIndex:0]

popToViewController用法

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

或

for (UIViewController *controller inself.navigationController.viewControllers) {

if ([controller isKindOfClass:[你要跳转到的Controller class]]) {

[self.navigationControllerpopToViewController:controller animated:YES];

}

}
