I am trying to make an app that lets you record a sound to the Apple Watch and have it play it back using the audioplayer. Thanks

推荐答案

尝试使用 WKAudioFilePlayerItem 吗?使用这个类播放音频，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!

他们在程序中扮演着不同的角色.audioFile 用于定义 NSURL.例如，如果您有名为bicycle.mp3"的文件，您可以像这样定义 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") 

当你有一个 soundpath 时，你可以在 audioFile 中把它变成一个 NSURL:

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

audioFile = WKAudioFileAsset.init(URL: soundPathURL)

当你有一个 audioFile 时，你把它放在 audioPlayerItem

When you have a audioFile, you put it inside the audioPlayerItem

audioItem = WKAudioFilePlayerItem.init(asset: audioFile)

当你有 audioItem 时，你把它放在 audioPlayer

When you have audioItem, you put it inside the audioPlayer

    `audioPlayer = WKAudioFilePlayer(playerItem: audioItem)`

最后，你可以把代码audioPlayer.play()放在你想播放声音的地方

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

享受吧！
