ios - Swift 创建 UIButton 和 UIView 颜色更改的通用扩展

Question

就我而言，我正在尝试创建多个按钮。在这里，每个按钮都放置在单独的 UIView 上。该按钮的工作方式类似于基于选择的单个部分。我在每个按钮 acton 方法中更改其标题颜色和 UIView 颜色。在这里，我需要为所有按钮标题和 UIView 颜色更改创建一个通用扩展。一旦单击按钮，需要将值传递给扩展或函数来更改选择按钮的颜色。这是我试图减少代码重复和 LOC。

注意: 下面我只发布了一个按钮代码，但我有很多按钮。我想将其设为公共(public)类并传递值来更改颜色。如何实现这一目标？

第一个按钮操作

 @IBAction func firstButtonClick(_ sender: Any) {
        self.onetimeView.backgroundColor =  colorLiteral(red: 0.184337255, green: 0.683529412, blue: 0.976475882, alpha: 1)
        self.dailyView.backgroundColor =  colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
        self.weeklyView.backgroundColor =  colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
        self.fiftydaysView.backgroundColor =  colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
        self.monthlyView.backgroundColor =  colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)

        self.onetimeButton.setTitleColor(UIColor.selectedColor, for: .normal)
        self.dailyButton.setTitleColor(UIColor.disabledColor, for: .normal)
        self.weeklyButton.setTitleColor(UIColor.disabledColor, for: .normal)
        self.fiftydaysButton.setTitleColor(UIColor.disabledColor, for: .normal)
        self.monthlyButton.setTitleColor(UIColor.disabledColor, for: .normal)
    }

@IBAction func secondButtonClick(_ sender: Any) {
       self.onetimeView.backgroundColor =  colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
       self.dailyView.backgroundColor =  colorLiteral(red: 0.184337255, green: 0.683529412, blue: 0.976475882, alpha: 1)
       self.weeklyView.backgroundColor =  colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
       self.fiftydaysView.backgroundColor =  colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
       self.monthlyView.backgroundColor =  colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)

       self.onetimeButton.setTitleColor(UIColor.disabledColor, for: .normal)
       self.dailyButton.setTitleColor(UIColor.selectedColor, for: .normal)
       self.weeklyButton.setTitleColor(UIColor.disabledColor, for: .normal)
       self.fiftydaysButton.setTitleColor(UIColor.disabledColor, for: .normal)
       self.monthlyButton.setTitleColor(UIColor.disabledColor, for: .normal)
    }

extension UIColor {
    static var selectedColor = UIColor.init(red: 47/255, green: 174/255, blue: 248/255, alpha: 1)
    static var disabledColor = UIColor.init(red: 170/255, green: 170/255, blue: 170/255, alpha: 1)
}

您可以创建一个子类，例如:

类 PrimaryButton: UIButton {}
