“嵌入"UIViewController在另一个 [英] "Embed" UIViewController within another

问题描述

我有一个UIViewController(DetailViewController)，它由顶部的导航栏和覆盖屏幕其余部分的UIView组成.可以使用除DetailViewController之外的UIViewController来控制UIView吗?

I have a UIViewController (DetailViewController) consisting of a navigation bar on the top and a UIView covering the rest of the screen. Is it possible to control the UIView with a UIViewController other than DetailViewController?

推荐答案

您可以执行此操作，但一定不要忘记调用Apple嵌入UIViewControllers所需的方法.否则，操作系统将不会调用您的视图控制器来处理某些事件.

You can do this, but you must not forget to call Apple's required methods for embedding UIViewControllers. Otherwise, your view controller will not get called by the OS to handle certain events.

要添加视图控制器，请执行以下操作:

To add the view controller:

[self addChildViewController:childViewController];                 
[self.view addSubview:childViewController.view];
[childViewController didMoveToParentViewController:self];

要删除视图控制器，请执行以下操作:

To remove the view controller:

[childViewController willMoveToParentViewController:nil];  
[childViewController.view removeFromSuperview];            
[childViewController removeFromParentViewController];
