设备方向更改后窗口子视图不旋转
我正在 AppDelegate 中创建一个带有标签的 UIView 并显示它，如下所示：
[window addSubview:self.roundedCornerView];
问题是当我旋转设备时，带有标签的视图根本不旋转。标签中的文字方向也错误。我的应用程序中的窗口有另一个子视图，即 UIViewControllers 子视图，并且它旋转得很好。
我是否需要在 AppDelegate 中创建另一个 UIViewController 并将创建的视图附加到它，然后将其子类化并允许界面方向以使 roundedCornerView 旋转？
更新 好的，我尝试通过创建新的 ViewController 并对其进行子继承来实现此目的，这里是我的 AppDelegate 中的代码：
ActivityIndicatorWithLabelViewController *aiWithLabel = [[[ActivityIndicatorWithLabelViewController alloc] init] autorelease];
aiWithLabel.textOfTheLabel = text;
[window addSubview:aiWithLabel.view];

如您所见，这里有一些调试代码。当我将设备从肖像旋转到风景时，我进入了支撑方向！以及 LADNSCAPE NSLog。删除标签工作正常，但是当我添加新标签时，它仍然以错误的方向显示（文本）。我做错了什么？
I'm creating an UIView with a label inside AppDelegate and displaying it like this:
[window addSubview:self.roundedCornerView];
Problem is when I rotate the device the view with label don't rotate at all. The text in the label is in wrong orientation as well. Window in my application got another subview which is the UIViewControllers subview and it is rotating fine.
Do I need to create another UIViewController in my AppDelegate and attach created view to it, then subclassing it and allowing for interface orientation in order to get roundedCornerView to rotate?
UPDATE
Ok I've tried to do this by creating new ViewController and sublcassing it here is code in my AppDelegate:
ActivityIndicatorWithLabelViewController *aiWithLabel = [[[ActivityIndicatorWithLabelViewController alloc] init] autorelease];
aiWithLabel.textOfTheLabel = text;
[window addSubview:aiWithLabel.view];

As you see there is some debug code in here. When I'm rotating the device from potrait to landscape I get ENTERING SUPPORTE ORIENTATION! as well as LADNSCAPE NSLog. Removing label is working fine, but when I'm adding new one it is still presented (the text) in wrong orientation. What I am doing wrong?

UIWindow 应该只有一个定义根 UIViewController 的子视图。我相信 UIWindow 仅将旋转事件转发到其第一个子视图。
创建一个容器 UIView 并将子视图移入其中。
UIWindow should only have one subview which defines the root UIViewController. I believe that UIWindow only forwards rotation events to its first subview.
Create a single container UIView and move your subviews into it.
解决方案是遵循以下步骤：
在子视图的.m文件中，在视图界面顶部添加代码：
在 subView 的 .m 文件中添加代码
另外在 subView 的 .h 文件中添加此行。
现在是时候使用上面添加的代码来更改子视图中的方向了。
在 window 或 self.view 中添加子视图时，如下所示：
参考取自 AGWindowView
Solution is follow below steps :
In subView's .m file add code on top of interface of you view:
In subView's .m file add code
Also In subView's .h file add this line.
Now time to use above added code for orientation change in subview.
While adding subview in window or self.view like this :

窗口子视图不会自行旋转，它们通常在视图控制器的帮助下旋转。
您可以将要旋转的视图添加到视图控制器，然后将其添加到窗口，或者您可以注册设备方向更改通知并自行旋转它们。
Window subviews don't rotate by themselves, they usually rotate with the help of a view controller.
You could either add the views you want rotated to a view controller and then add that to the window, or you could register for device orientation changes notifications and rotate them yourself.
