如何禁用标准的UIButton触摸事件

Question

在我的应用程序中，我添加了一个UIButton，但没有让UIButton的标准触摸事件变暗，而是在触摸事件结束后变为标准颜色，而是要添加一个动画，当您单击UIButton时，按钮会变小，然后，当触摸事件结束时，UIButton会在触摸事件结束后恢复为常规大小。 到目前为止，我已经键入了这段代码，但是它似乎没有用。 请让我知道如何完成此动画。

// whatsTheGame is the UIButton I have

@IBAction func whatsTheGame(_ sender: UIButton) {

    logo.isHighlighted = false

    UIView.animate(withDuration: 0.3) {

        if let centerLogo = self.logo {

            centerLogo.transform = CGAffineTransform(scaleX: 0.7, y: 0.7)
        }
    }
}

override func touchesCancelled(_ touches: Set<UITouch>, with event: UIEvent?) {
    super.touchesCancelled(touches, with: event)

    UIView.animate(withDuration: 0.3) {

        if let centerLogo = self.logo {

            centerLogo.transform = CGAffineTransform(scaleX: 1, y: 1)
        }
    }
}

override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
    super.touchesEnded(touches, with: event)

    UIView.animate(withDuration: 0.3) {

        if let centerLogo = self.logo {

            centerLogo.transform = CGAffineTransform(scaleX: 1, y: 1)
        }
    }
}

添加内部Touch Up和Touch Down事件

@IBAction func onTouchUpInside(_ sender: Any) {

    let button = sender as! UIButton

    UIView.animate(withDuration: 0.3) {

        button.transform = CGAffineTransform(scaleX: 1, y: 1)
    }
}

@IBAction func onTouchDown(_ sender: Any) {

    let button = sender as! UIButton

    UIView.animate(withDuration: 0.3) {

        button.transform = CGAffineTransform(scaleX: 0.7, y: 0.7)
    }
}
