Question

我正在使用Xcode 7.3.1和iOS 9，并且遇到AVAudioPlayer播放声音的问题。我已经尝试了所有可能的解决方案，没有任何作用这是我的代码

        let mp3Url = NSBundle.mainBundle().URLForResource("BCA", withExtension:"mp3")!

        var player = AVAudioPlayer()

        do {
            player = try AVAudioPlayer(contentsOfURL: mp3Url)
            player.prepareToPlay()
            player.play()
        } catch let error as NSError {
            print(error.description)
        }

在 player.play（）并使用 po player 设置断点之前，声音才会播放。然后会播放声音。

任何想法对我都有帮助。

试试这个：

    var player: AVAudioPlayer?

    func playSound(){
        guard let url = Bundle.main.url(forResource: "alert_song", withExtension: "mp3") else {
            print("MP3 resource not found.")
            return
        }

        print("Music to play : \(String(describing: url))")
        do {
            try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
            try AVAudioSession.sharedInstance().setActive(true)

            player = try AVAudioPlayer(contentsOf: url)
            guard let player = player else { return }
            player.play()
        } catch let error {
            print(error.localizedDescription)
        }

    }

试试这个：

在使用调试脚本之前，AVAudioPlayer无法播放声音
