ios - 如何在 10 个按钮中快速创建 1 个带颜色的微光渐变

Question

我尝试创建一个包含 10 个按钮的 View 来创建 1 个运行超过 10 个 View 按钮的渐变动画，但不能。只为按钮制作渐变。大家有什么办法吗？

这是我的代码。我尝试过，但我希望它对标题按钮的整个颜色进行渐变

 let insets: UIEdgeInsets = UIEdgeInsets(top: 10, left: 10, bottom: 10, right: 10)

    let gradient = CAGradientLayer()
    gradient.frame = self.view.bounds//path.bounds
    gradient.colors = [UIColor.magenta.cgColor, UIColor.cyan.cgColor]
    let shapeMask = CAShapeLayer()
    let path = UIBezierPath(rect: button1.frame)
    path.append(UIBezierPath(rect: button2.frame))
    path.append(UIBezierPath(rect: button3.frame))


    shapeMask.path = path.cgPath
    gradient.mask = shapeMask

    let whiteMask = CAShapeLayer()
    whiteMask.fillColor = UIColor.white.cgColor
    let whitePath = UIBezierPath(rect: button1.frame.inset(by: insets))
    whitePath.append(UIBezierPath(rect: button2.frame.inset(by: insets)))
    whitePath.append(UIBezierPath(rect: button3.frame.inset(by: insets)))
    whiteMask.path = whitePath.cgPath
    self.bgView.layer.addSublayer(gradient)
    self.bgView.layer.addSublayer(whiteMask)
