ios - 如何在 swift3 中播放 mp3 文件？

Question

开始学习ios开发，卡在一个地方。我播放 mp3 文件的代码是

var bombSoundEffect: AVAudioPlayer!
let path = Bundle.main.path(forResource: "faded", ofType:"mp3")!
let url = NSURL(fileURLWithPath: path)

 do {
        let sound = try AVAudioPlayer(contentsOf: (url as NSURL) as URL)
        bombSoundEffect.play()

    } catch {
        print("couldn't load file :(")
    }
    if bombSoundEffect != nil {
        bombSoundEffect.stop()
        bombSoundEffect = nil
        }

但是，当我点击按钮时，我的文件没有播放。这首歌正在正常播放。

尝试使用以下代码:

var bombSoundEffect: AVAudioPlayer?

func playAudio() {
    let url = Bundle.main.url(forResource: "faded", withExtension: "mp3")!

    do {
        bombSoundEffect = try AVAudioPlayer(contentsOf: url)
        guard let bombSound = bombSoundEffect else { return }

        bombSound.prepareToPlay()
        bombSound.play()
    } catch let error {
        print(error.localizedDescription)
    }
}
