Question

我正在制作点击游戏，这是带有动画的按钮。它非常慢，我想加快速度，因此当用户点击时，它将重置动画并计算点击次数。

目前，如果在动画仍在继续播放时再次轻按，则会丢失轻按的速度。

@IBAction func slimeTap(_ sender: UIButton) {
    tapCount += tapIncrease
    checkLevel(tapCount)
    UIView.animate(withDuration: 0.03, animations: {
        //shrink
        self.playSound()
        sender.transform = CGAffineTransform(scaleX: 0.8, y: 0.8)
    }, completion: {_ in
        //change it back to how it was
        //grow
        UIView.animate(withDuration: 0.05, animations: {
           sender.transform = CGAffineTransform(scaleX: 1, y: 1)
        })
    })
}

尝试添加.layer.removeAllAnimations()来删除图层上所有现有的动画，并添加.allowUserInteraction作为动画选项来启用和注册用户点击事件：

@IBAction func slimeTap(_ sender: UIButton) {
    tapCount += tapIncrease
    checkLevel(tapCount)

    resizingView.layer.removeAllAnimations()

    UIView.animate(withDuration: 0.3, delay: 0, options: [.allowUserInteraction], animations: {
        self.playSound()
        sender.transform = CGAffineTransform(scaleX: 0.8, y: 0.8)
    }) { _ in
        UIView.animate(withDuration: 0.5, delay: 0, options: [.allowUserInteraction], animations: {
            sender.transform = CGAffineTransform(scaleX: 1, y: 1)
        })
    }
}
