Swift 為 UIButton 和 UIView 創建通用擴展

Question

就我而言，我正在嘗試創建多個buttons 。 在這里，每個按鈕放置在單獨的 UIView 上。 這個按鈕就像一個基於選擇的單個部分它的標題顏色和UIView顏色我在每個按鈕操作方法中進行更改。 在這里，我需要為所有按鈕標題和 UIView 顏色變化創建一個通用擴展。 一次，按鈕單擊需要將值傳遞給擴展或 function 以更改 colors 為selection按鈕。 這是我正在嘗試減少代碼重復和 LOC。

NOTE:下面我只發布了一個按鈕代碼，但我有很多按鈕。 我想讓它成為常見的 class 並傳遞值來更改 colors。 如何做到這一點？

第一個按鈕操作

 @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)
}

Answer 1

您可以創建一個子類，如：

class 主按鈕：UIButton { }

Answer 2

將您的按鈕和視圖存儲在某種數據結構中並對其進行迭代。 創建一個 function，它將在作為參數傳遞的視圖上設置selectedColor並在 rest 上設置disabledColor 。

typealias Section = (UIButton, UIView)

let sections: [Section] = [
    (button: onetimeButton, view: onetimeView),
    (button: dailyButton, view: dailyView),
    (button: weeklyButton, view: weeklyView),
    (button: fiftydaysButton, view: fiftydaysView),
    (button: monthlyButton, view: monthlyView),
]

func select(_ section: Section) {
    sections.forEach { (section) in
        section.0.setTitleColor(UIColor.disabledColor, for: .normal)
        section.1.backgroundColor = UIColor.disabledColor
    }

    section.0.setTitleColor(UIColor.selectedColor, for: .normal)
    section.1.backgroundColor = UIColor.selectedColor
}

// in UIButton click call
select((onetimeButton, onetimeView))
