AVPlayer有一套自有的缓存系统，貌似不支持播放过的视频的缓存。但是支持查询缓存进度，AVPlayerItem.loadedTimeRanges可以获得load progress，并且该属性支持KVO，可以通过AVPlayer.currentItem获取到与AVPlayer关联的AVPlayerItem。

你好！ 意思视频不能缓存吗？

应该是做了缓存，不过是黑匣子，都是系统API，所以不能断定。想自己做缓存的，可以使用代理之类的，使用自定义的下载模块。

我使用您的Demo测试之后，在无网络状态下是不能播放的，所以应该没有缓存，因为一边播放一边缓存，不自定义播放器的情况下，可以做到吗？

目前来看，使用默认配置是无法做到的。可行的技术方案是本地起一个HTTPServer，后者使用系统API AVAssetResourceLoader.

@zhzhy
只能这样了！通过本地HTTPServer来达成模拟数据流读取了！ 感谢哈！ 能否一起来完成一下啊？相比很多App会有需要的哦！

这方面有很多成熟的开源库可以利用，并且我认为使用AVAssetResourceLoader更方便，毕竟系统库。所以，重新搞一个的意义在哪里？

嗯！ 这个问题值得思考，我尝试一下怎么从AVAssetResourceLoader中进行缓存视频吧！

能否简单描述一下怎样缓存的流程吗？比如使用AVPlayer去播放一个视频，这个时候需要怎样去做这个缓存的流程呢？
