我在处理程序中为触摸设置动画：

        // https://stackoverflow.com/questions/46021640/how-to-sequence-two-animations-with-delay-in-between
        let scaleForwardAnimationDuration: TimeInterval = 0.15
        let transformBackAnimationDuration: TimeInterval = 0.1
        let animationDuration: TimeInterval = scaleForwardAnimationDuration + transformBackAnimationDuration

        UIView.animateKeyframes(withDuration: animationDuration, delay: 0, options: [], animations: {
            UIView.addKeyframe(withRelativeStartTime: 0, relativeDuration: scaleForwardAnimationDuration) {
                sender.transform = CGAffineTransform(scaleX: 0.75, y: 0.75)
            }

            UIView.addKeyframe(withRelativeStartTime: scaleForwardAnimationDuration, relativeDuration: transformBackAnimationDuration) {
                sender.transform = .identity
            }
        })

这导致输入掉在地板上由于 .allowUserInteraction 外部动画块的选项中没有
