swift-弹出分享视图view之自定义带动画的view

上一篇这里，写了和UIAlertController有关的弹出视图，但是在实际情况中，我发现其他各大应用的弹出的视图都是没有带弧度的那一种，从设计理念来说，UIAlertController的方式会显得比较突兀不太友好。所以这里分享的是另外一种与UIAlertController无关的视图

• 支持一行动态显示
• 支持两行动态显示
• 不支持滑屏(一般的分享想必也不会有超过8个的)

弹出动画：

 buttonY += kScreenHeight
customButton.frame = CGRect(x: buttonX, y: buttonY, width: CGFloat(buttonWeight), height: CGFloat(buttonHeight))
customButton.alpha = 0
DispatchQueue.main.asyncAfter(deadline: .now() + 0.03 * Double(i), execute: {
     UIView.animate(withDuration: 0.35, delay: 0, usingSpringWithDamping: 0.8, initialSpringVelocity: 0.8, options: .curveEaseIn, animations: { 
          customButton.alpha = 1
          customButton.frame = CGRect(x: buttonX, y: buttonY - kScreenHeight, width: CGFloat(buttonWeight), height: CGFloat(buttonHeight))
           }, completion: nil)
    })

点击按钮时显示的动画：

func menuBtnTouchUpInside(_ button: UIButton){
     button.imageView?.clipsToBounds = false
     for customButton in self.meunButtons {
            customButton.titleLabel?.alpha = 0
            UIView.animate(withDuration: 0.3, animations: {
                customButton.alpha = 0
                if customButton.isEqual(button){
                    customButton.imageView?.transform = CGAffineTransform(scaleX: 3, y: 3)
                }else{
                    customButton.imageView?.transform = CGAffineTransform(scaleX: 0.3, y: 0.3)
                }
            }, completion: { (bool ) in       
            })
        }
        DispatchQueue.main.asyncAfter(deadline: .now() + 0.3) {
            self.meunButtons.removeAll()
            self.bottomBtnDidClick(button)
        }
        if delegate != nil {
            self.delegate?.didClickOnItemAtIndex(index: button.tag)
        }
    }
