如何禁用標准的UIButton觸摸事件

Question

在我的應用程序中，我添加了一個UIButton，但沒有讓UIButton的標准觸摸事件變暗，而是在觸摸事件結束后變為標准顏色，而是要添加一個動畫，當您單擊UIButton時，按鈕會變小，然后，當觸摸事件結束時，UIButton會在觸摸事件結束后恢復為常規大小。 到目前為止，我已經鍵入了這段代碼，但是它似乎沒有用。 請讓我知道如何完成此動畫。

// 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)
        }
    }
}

添加內部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)
    }
}
