Use AVAssetImageGenerator. 使用AVAssetImageGenerator。

I haven't personally used it, but it looks pretty straight forward if you've used AVFoundation before. 我没有亲自使用它，但如果您之前使用过AVFoundation，它看起来很直接。 Looks like you just initialize it with an asset and then you can generate a CGImage at a specific time using copyCGImageAtTime:actualTime:error: 看起来你只是用资产初始化它然后你可以使用copyCGImageAtTime在特定时间生成CGImage：actualTime：error：
