无法使用 CATiledLayer 正确设置视图动画

带有 CATiledLayer 的 UIView 可以有动画吗？

如果我调用以下内容：

[myContentView setNeedsDisplay];

CGContextRef context = UIGraphicsGetCurrentContext();
[UIView beginAnimations:nil context:context];
[UIView setAnimationTransition: UIViewAnimationTransitionCurlUp forView:self.view 缓存:YES];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:10]; [UIView提交动画]；

如果 UIView 是没有 CATiledLayer 的“普通”UIView，这将很有效。但是，一旦我添加了 CATiledLayer 类型的子图层，动画就无法正常工作。页面翻转有效，但在动画完成之前不会显示底层页面（只是空白）。

我已经尝试过 [myContentView setNeedsDisplay];在动画块之前、之后甚至中间。如果 myContentView 有 CATiledLayer，则没有区别。

任何帮助表示赞赏。

Can UIViews with a CATiledLayer have animations?

If I call the following:

[myContentView setNeedsDisplay];

CGContextRef context = UIGraphicsGetCurrentContext();
[UIView beginAnimations:nil context:context];
[UIView setAnimationTransition: UIViewAnimationTransitionCurlUp forView:self.view cache:YES];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:10];
[UIView commitAnimations];

This will work well if the UIView is a "normal" UIView without a CATiledLayer. However as soon as I add a sublayer of type CATiledLayer, the animations does not work correctly.
The page flip works, but the underlying page is not shown (just blank) until the animation is finished.

I have tried [myContentView setNeedsDisplay]; before, after and even in the middle of the animation block. No difference if myContentView has a CATiledLayer.

Any help appreciated.
