第一种方法：如果使用导航 第一个按钮方法： [self.navigationController pushViewController:secondVC animated:YES]; 第二个按钮方法： [self.navigationController popViewControllerAnimated:YES]; 第二种方法：如果使用模态 第一个按钮方法： [self presentViewController:secondVC animated:YES completion:nil]; 第二个按钮方法： [self dismissViewControllerAnimated:YES completion:nil];

关于ios中 viewcontroller的跳转问题，其中有一种方式是采用navigationController pushViewController 的方法，比如我从主页面跳转到了一级页面，又从一级页面跳转到了二级页面，然后从二级页面跳转到了三级页面，依次类推。，如果一级一级的返回我知道是没有问题的，调用navigationController&popViewControllerAnimated就行了。。但是某些情况下我可能想要马上回到主页面，而不是一级一级的返回（如果有很多层会很累的），那该怎么办呢？
返回根页面vc用 ：
[self.navigationController popToRootViewController
返回指定的某个vc用下面（通过index定位）&
[self.navigationController popToViewController:[self.navigationController.viewControllers objectAtIndex:2]
animated:YES];
或（通过class定位）
(UIViewController *controller in self.navigationController.viewControllers) {
([controller isKindOfClass:[你要跳转到的Controller class]])
&&&&&&&&[self.navigationController
popToViewController:controller animated:YES];
排名：千里之外
