Swift 2 - AVAudioPlayer不播放音频-Java 学习之路

我正试图用AVAudioPlayer播放声音，但它没有播放 . 我尝试了一个设备（iPhone 6s）和模拟器 . 我没有收到任何错误并记录下来 . 当我在audioPlayer.play（）之前设置一个断点并跳过它时会播放几秒钟然后停止 . 我的代码：

let soundURL = NSBundle.mainBundle().URLForResource("test", withExtension: "mp3")
        do {
            try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
            try AVAudioSession.sharedInstance().setActive(true)
            if let soundURL = soundURL {
                let audioPlayer = try AVAudioPlayer(contentsOfURL: soundURL)
                audioPlayer.volume = 1
                audioPlayer.delegate = self
                audioPlayer.prepareToPlay()
                print(audioPlayer.duration)
                audioPlayer.play()
                print("PLAYED")
            }
        }catch {
            print("Error getting the audio file")
        }

这是一个可行的例子 . 我不知道在哪里，与你的其余代码相比，你有你上面显示的代码 . 确保您的设备音量不是静音且已打开...

//declare these as instance variables
var AudioURL = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("FileName", ofType: "mp3")!)
var AudioPlayer = AVAudioPlayer()

//inside viewDidLoad establish your AVAudioSession and configure the AudioPlayer with the contents of URL
override func viewDidLoad() {
   super.viewDidLoad()

   do {
       try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
        //print("AVAudioSession Category Playback OK")
    do {
        try AVAudioSession.sharedInstance().setActive(true)
          //print("AVAudioSession is Active")
    } catch let error as NSError {
        print(error.localizedDescription)
    }
   } catch let error as NSError {
       print(error.localizedDescription)
   }


   do {
       try AudioPlayer  = AVAudioPlayer(contentsOfURL: AudioURL, fileTypeHint: nil)
   } catch {
       print("errorin do-try-catch")
   }
}

  //play audio
  @IBAction func playAudio(sender: AnyObject){
      AudioPlayer.play()
  }
