【问题描述】：
我正在 AppDelegate 中创建一个带有标签的 UIView，并像这样显示它：
[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。标签中的文本也方向错误。我的应用程序中的窗口有另一个子视图，它是 UIViewControllers 子视图，它可以正常旋转。
我是否需要在我的 AppDelegate 中创建另一个 UIViewController 并将创建的视图附加到它，然后对其进行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 并将其子类化来实现这一点，这是我的 AppDelegate 中的代码：
ActivityIndicatorWithLabelViewController *aiWithLabel = [[[ActivityIndicatorWithLabelViewController alloc] init] autorelease];
aiWithLabel.textOfTheLabel = text;
[window addSubview:aiWithLabel.view];
ActivityIndicatorWithLabelViewController 类在这里可见：

self.textActivityIndicatorLabel.text = @"";
// self.textActivityIndicatorLabel.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleWidth;
[self.roundedCornerView addSubview:textActivityIndicatorLabel];
self.textActivityIndicatorLabel.text = textOfTheLabel;

[self.view addSubview:self.roundedCornerView];
//self.view = self.roundedCornerView;

[self.textActivityIndicatorLabel removeFromSuperview];
[self.textActivityIndicatorLabel release];
self.textActivityIndicatorLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];
self.textActivityIndicatorLabel.backgroundColor = [UIColor clearColor];
self.textActivityIndicatorLabel.textAlignment = UITextAlignmentCenter;
self.textActivityIndicatorLabel.textColor = [UIColor whiteColor];
self.textActivityIndicatorLabel.font = [UIFont systemFontOfSize:22];
self.textActivityIndicatorLabel.text = @"Landscape";
[self.roundedCornerView addSubview:textActivityIndicatorLabel];
NSLog(@"LANDSCAPE");
}
NSLog(@"ENTERING SUPPORTED ORIENTATION!");
return YES;
}
@end
如您所见，这里有一些调试代码。当我将设备从纵向旋转到横向时，我得到了 ENTERING SUPPORTE ORIENTATION！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？
