MPMusicPlayerController缓冲/预加载 [英] MPMusicPlayerController buffering / preloading

问题描述

有没有办法在调用-play之前制作MPMusicPlayerController缓冲区内容？或者在设置队列时默认执行此操作？ AVAudioPlayer有-prepareToPlay方法，我听说AVQueuePlayer会自动开始缓冲下一个项目，但MPMusicPlayerController是否有相同的行为？

Is there a way to make MPMusicPlayerController buffer content before I call -play? Or does it do this by default when you set a queue? AVAudioPlayer has the -prepareToPlay method and I've heard that AVQueuePlayer starts buffering the next item automatically, but does MPMusicPlayerController have the same behaviour?

推荐答案

这个问题的答案是在iOS 6 beta文档中，如果有人想知道的话。由于NDA，不能说更多。

The answer to this question is in the iOS 6 beta docs, if anyone is wondering. Can't say much more because of NDA.

编辑：根据要求，由于NDA已被取消，所以答案是：截至iOS 6， MPMusicPlayerController ，如 MPMoviePlayerController 实现 MPMediaPlayback 协议，其方法如 -prepareToPlay 。

As requested, since the NDA has been lifted, here's the answer: As of iOS 6, MPMusicPlayerController, like MPMoviePlayerController implements the MPMediaPlayback protocol, which has methods like -prepareToPlay.
