推荐答案

使用AVPlayer代替AVAudioPlayer进行音频流传输.可以这么简单-

Use AVPlayer instead of AVAudioPlayer for streaming audio. It can be as simple as this --

let urlString = "http://www.example.com/song.mp3"
let url = NSURL(string: urlString)

var avPlayer = AVPlayer(URL: url)
avPlayer.play()

还可以在AVPlayer.status属性上设置观察者以管理其更改状态.查看: https://stackoverflow.com/a/13156942/2484290 (目标c)

You can also set an observer on the AVPlayer.status property to manage its changing status. Check out: https://stackoverflow.com/a/13156942/2484290 (objective c)

当然，AVPlayer文档在这里: https://developer.apple.com/LIBRARY/ios/documentation/AVFoundation/Reference/AVPlayer_Class/index.html#//apple_ref/occ/cl/AVPlayer

And of course the AVPlayer docs are here: https://developer.apple.com/LIBRARY/ios/documentation/AVFoundation/Reference/AVPlayer_Class/index.html#//apple_ref/occ/cl/AVPlayer
