this will pop the top controller from navigation controller stack!

这将弹出顶部控制器从导航控制器堆栈!

 [self.navigationController popViewControllerAnimated:YES];

and if you are not aware of UINavigationController and its uses then follow this link

如果您不知道UINavigationController及其用途，请按此链接进行

You need to use a UINavigationController. This maintains a stack of your view controllers. You can modify your view stack by calling pushViewController:animated and popViewController:animated.

你需要使用UINavigationController。这将维护视图控制器的堆栈。你可以通过调用pushViewController:animated和popViewController:animated来修改你的视图堆栈。

Initialize your instance of UINavigationController with a rootViewController (your first view controller), and then present your UINavigationController in some way, then all you need is to play around with your UINavigationController instance.

使用rootViewController(您的第一个视图控制器)初始化UINavigationController实例，然后以某种方式显示UINavigationController，然后您所需要的就是使用UINavigationController实例。

if you are pushing the view controller use:

      [self.navigationController popViewControllerAnimated:NO];

else if you are using a modal transition use:

如果你使用的是模态过渡使用:

      [self dismissViewControllerAnimated:YES completion:^{
          //Stuff after dismissing
        }];
