如何快速按下按钮在 Xcode 上生成声音？

Question

这是我的以下 Xcode 项目代码。当我按下“play()”时，会发出短促的鼓声。问题是，当我连续多次点击自定义视图时，我希望连续出现快速的鼓声。但是，声音会在完整剪辑（2 秒）完成后出现，留下大量死区。我尝试了很多不同的方法，但我做不到。

@IBOutlet weak var tabla: TablaHead!

var tablaSoundUrl = NSURL(fileURLWithPath: Bundle.main.path(forResource: "TablaSound", ofType: "mp3")!)
var tablaAudioPlayer = AVAudioPlayer()


override func viewDidLoad() {
    super.viewDidLoad()
    tablaAudioPlayer = try! AVAudioPlayer(contentsOf: tablaSoundUrl as URL)
}

@IBAction func tapped(_ sender: UITapGestureRecognizer) {
    if sender.state == .ended {
        playNoise()
    }
}

public func playNoise() {
    if (tablaAudioPlayer.isPlaying) {
        tablaAudioPlayer.stop()
        tablaAudioPlayer.play()
    } else {
        tablaAudioPlayer.play()
    }
}

试试这样的

@IBOutlet weak var tabla: TablaHead!

var tablaSoundUrl = NSURL(fileURLWithPath: Bundle.main.path(forResource: "TablaSound", ofType: "mp3")!)
var tablaAudioPlayer = AVAudioPlayer()
var tapsCount = 0

override func viewDidLoad() {
    super.viewDidLoad()
    tablaAudioPlayer = try! AVAudioPlayer(contentsOf: tablaSoundUrl as URL)
}

@IBAction func tapped(_ sender: UITapGestureRecognizer) {
    tapsCount += 1
    if sender.state == .ended && tapsCount == 1 {
        playNoise()
    }
}

public func playNoise() {
    tapsCount -= 1
    tablaAudioPlayer.play()
    if tapsCount > 0 {
        playNoise()
    }
}
