推荐答案

尝试使用WKAudioFilePlayerItem吗? 要使用此类播放音频，您需要声明3个变量:

Try using WKAudioFilePlayerItem ? To use this class to play audio, you need to declare 3 variables:

var audioFile: WKAudioFileAsset!
var audioItem: WKAudioFilePlayerItem!
var audioPlayer: WKAudioFilePlayer!

它们在程序中具有不同的角色.对于audioFile，用于定义NSURL.例如，如果您有一个名为"bicycle.mp3"的文件，则可以这样定义URL路径:

They have different role inside the program. For audioFile is used to define NSURL. For example, if you have file called "bicycle.mp3", you can define the URL path like this :

let soundPath = NSBundle.mainBundle().pathForResource("bicycle", ofType: "mp3")
print("load file") 

当您拥有soundpath时，可以在audioFile内将其设为NSURL:

when you have a soundpath, you make it a NSURL inside audioFile:

audioFile = WKAudioFileAsset.init(URL: soundPathURL)

拥有audioFile时，将其放在audioPlayerItem

audioItem = WKAudioFilePlayerItem.init(asset: audioFile)

当您拥有audioItem时，将其放在audioPlayer

When you have audioItem, you put it inside the audioPlayer

    `audioPlayer = WKAudioFilePlayer(playerItem: audioItem)`

最后，您可以将代码audioPlayer.play()放在要播放声音的位置

Finally, you can put the code audioPlayer.play() where you want to play the sound

享受！
