blocks|key|673372|text|要访问父视图控制器，您可以使用self.parentViewController。拥有它后，只需使用其view属性即可访问其视图|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|673373|entityMap^0|F|P|1F|4|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

To access the parent View controller you can use <code>self.parentViewController</code>. Once you have it you can access its view simply by using its <code>view</code> property

blocks|key|673401|text|使用iOS+5.x%2B的用户请注意|type|unstyled|depth|inlineStyleRanges|entityRanges|data|673402|self+parentViewController现在返回nil。现在，您必须使用self+presentingViewController才能获得相同的结果。有关升级代码库的更多信息和其他解决方法，请参阅此博客文章：http://omegadelta.net/2011/11/04/oh-my-god-they-killed-parentviewcontroller/|offset|length|style|CODE|673403|entityMap|0|LINK|mutability|MUTABLE|url|http://omegadelta.net/2011/11/04/oh-my-god-they-killed-parentviewcontroller/^0|0|0|P|T|3|15|T|31|24|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@$D|R|E|S|F|G]|$D|T|E|U|F|G]|$D|V|E|W|F|G]]|9|@$D|X|E|Y|1|Z]]|A|$]]|$1|H|3|-4|5|6|7|10|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|O]]]]

Note to those using iOS 5.x+

<code>self parentViewController</code> now returns <code>nil</code>. You will now have to use <code>self presentingViewController</code> to achieved the same result. See this blog post for more information and additional work arounds for upgrading your code base: <a href="http://omegadelta.net/2011/11/04/oh-my-god-they-killed-parentviewcontroller/" rel="noreferrer">http://omegadelta.net/2011/11/04/oh-my-god-they-killed-parentviewcontroller/</a>

blocks|key|459223|text|以下是对我有效的方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|459224|-+(void)prepareForSegue:(UIStoryboardSegue+*)segue+sender:(id)sender+{
++++NSString+*+segueName+=+segue.identifier;
++++if+([segueName+isEqualToString:+@"child-view"])+{

++++++++[self+addChildViewController:childViewController];
++++}
}|code-block|syntax|javascript|459225|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

here's what worked for me:

<pre><code>- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
 NSString * segueName = segue.identifier;
 if ([segueName isEqualToString: @"child-view"]) {
 ChildViewController * childViewController = (ChildViewController *) [segue destinationViewController];
 [self addChildViewController:childViewController];
 }
}
</code></pre>

blocks|key|673494|text|现在，在他们杀死了|type|unstyled|depth|inlineStyleRanges|entityRanges|data|673495|self.parent|code-block|syntax|javascript|673496|您可以使用|673497|override+func+didMove(toParentViewController+parent:+UIViewController?)

Now after they have killed the 

<pre><code>self.parent

you can use 

<pre><code>override func didMove(toParentViewController parent: UIViewController?)
{ 
}
</code></pre>

blocks|key|459344|text|我使用objective+c块的方法来实现这一点。看一看这个块教程。https://www.youtube.com/watch?v=FS4JAy1Wy3w|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|459345|entityMap|0|LINK|mutability|MUTABLE|url|https://www.youtube.com/watch?v=FS4JAy1Wy3w^0|Y|17|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

I accomplish this using the objective c blocks approach. Take a look at this blocks tutorial.

I have a main view controller that takes care of the drawing for my 2D opengl ES view, and a child view controller buttonManager that determines what buttons to load and draw during launch.

Once the user presses on one of these buttons, this view controller is created and its view is supposed to come up, but the view never gets added but has been tested to work. Heres my code from the main view controller:

<pre><code> buttonManager=[[ButtonManager alloc] init];
 [self addChildViewController:buttonManager];
 [self.view addSubview:buttonManager.view];
</code></pre>

and heres my code to launch this view:

<pre><code>-(void)launchStopDialog: (NSString*)stopName {
 NSLog(@"stopdialog should be launched.");
 if (stopDialogController == nil)
 stopDialogController = [[StopDialogController alloc] initWithNibName:@"StopDialog" bundle:nil];
 if (stopDialogController)
 [stopDialogController presentWithSuperview:self.view.superview withStopName:stopName]; 
}
</code></pre>

how can i access a parent view controller's view from a child view controller?

我有一个主视图控制器，它负责2DOpenGL ES视图的绘制，还有一个子视图控制器buttonManager，它决定在启动时加载和绘制哪些按钮。一旦用户按下其中的一个按钮，这个视图控制器就会被创建，并且它的视图应该会出现，但是这个视图从来没有被添加过，但是它已经过了测试。下面是我在主视图控制器中的代码： buttonM...
