ios - AVFoundation - 音乐 iOS

Question

我一直在尝试将音乐添加到我的应用程序中，但没有特别成功。我一直在尝试使用 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并且没有播放音乐。谁能帮忙？

import UIKit
import AVFoundation

class ViewController: UIViewController{

    let var avPlayer: AVAudioPlayer!

     @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()
                }
            }
        }
    }
}
