AVFoundation -音乐iOS

Question

我一直试图把音乐添加到我的申请中，但没有取得特别的成功。我一直试图使用AVFoundation，我的代码如下：

    //MUSIC

    var audioPlayer = AVAudioPlayer()
    let audioPath = Bundle.main.path(forResource: "happyDays", ofType: "wav")


    do {

        try audioPlayer = AVAudioPlayer(contentsOf: URL(fileURLWithPath: audioPath!))

    }
    catch {
        // process error

    }

     audioPlayer.play()

我没有收到任何错误，但我的应用程序启动和音乐播放。有人能帮忙吗？

     @IBAction func btnPlayPauseAudio(_ sender: UIButton){

         if self.avPlayer != nil{

            if let myAudioUrl = Bundle.main.url(forResource: "myAudioFile", withExtension: "mp3"){

                if self.avPlayer.isPlaying{

                    self.avPlayer.pause()
                }
                else{

                    self.avPlayer = try AVAudioPlayer(contentsOf: myAudioUrl)

                    self.avPlayer.prepareToPlay()

                    self.avPlayer.play()
                }
            }
        }
    }
}
