SKAudioNode不加载来自网址的声音 [英] SKAudioNode not load sound from url

问题描述

我想从网址下载声音并播放一次：

I want download sound from url and play it once:

let sound = SKAudioNode(url:URL(string:"http://www.music.helsinki.fi/tmt/opetus/uusmedia/esim/a2002011001-e02-16kHz.wav")!)

sound.run(SKAction.play())

我也试过 .mp3 音乐。它不下载或流式传输并返回： nil

I tried .mp3 music too. It doesn't download it or stream and returns: nil

但此代码导致错误：

由于未捕获的异常终止应用
'com.apple.coreaudio.avfaudio'，原因：'必需条件为false：
file！= nil'
***第一次抛出调用堆栈：....

Terminating app due to uncaught exception 'com.apple.coreaudio.avfaudio', reason: 'required condition is false: file != nil' *** First throw call stack: ....

libc ++ abi.dylib：以$ $类型的未捕获异常终止b $ b NSException

libc++abi.dylib: terminating with uncaught exception of type NSException

推荐答案

我想你试试 AVAudioPlayer

var resourcePath = url  //your url
var objectData = Data(contentsOf: NSURL(string: resourcePath)!)
var error: Error!
do {
    audioPlayer = try AVAudioPlayer(objectData)
}
catch let error {
}
audioPlayer.numberOfLoops = 0
audioPlayer.volume = 1.0
audioPlayer.prepareToPlay()
if audioPlayer == nil {
    print("\(error.description)")
}
else {
    audioPlayer.play()
}
