如何限制按钮的音量(Swift)

我有为按钮添加声音的代码。

我怎样才能做到无论设备的声音状态如何，按键的音量始终处于同一水平？

var audioPlayer = AVAudioPlayer()

@IBAction func Sound(_ sender: UIButton) {
    guard UserDefaults.standard.bool(forKey: "SwitchState2") else { return }
    audioPlayer.play()
}

override func viewDidLoad() {
    super.viewDidLoad()
    let music = Bundle.main.path(forResource: "PBOING1", ofType: "WAV")
    do {
        audioPlayer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: music! ))
    }
    catch{
        print(error)
    }
}

Answer 1

尝试设置音量:audioplayer.volume = 0.0 到 1.0
