Iphone iOS-动画-不播放

我已经看了一些关于CAKeyFrameAnimation的指南，但我没有看到如何触发它们。我唯一能想到的是，我必须用它作为回报，但这对我来说没有多大意义

对于（NSUInteger count=0；count，看起来您正试图加载100幅图像，并在0.1秒内将它们全部循环。这不仅是非常荒谬的（这是1000帧/秒，CoreAnimation的上限是60帧/秒），但CoreAnimation在开始之前复制所有图像可能需要超过0.1秒的时间，这意味着它将在开始之前完成（因此不会出现动画）.
看起来你正试图加载100幅图像，并在0.1秒内将它们全部循环。这不仅是非常荒谬的（这是1000帧/秒，CoreAnimation的上限是60帧/秒），但CoreAnimation在开始之前复制所有图像可能需要超过0.1秒的时间，这意味着它将在开始之前完成（因此不会出现动画）。
我承认这是一个PEBKAC错误

谢谢大家的帮助。
我承认这是PEBKAC的错误

谢谢大家的帮助。
试试：

[myImages addObject:(id)[UIImage imageWithContentsOfFile:path].CGImage];

因为
cakeyKeyMeanimation
需要
CGImageRef
对象。
请尝试：

[myImages addObject:(id)[UIImage imageWithContentsOfFile:path].CGImage];

因为
CAKeyFrameAnimation
需要
cImageRef
对象。
我的建议是：不要发布与您的问题无关的代码。如果我知道代码中的缺陷在哪里，我会……但它符合并没有任何控制台错误或其他指示。仅供参考，您在
