Ios UITableView和UITextField边界颜色问题

我不熟悉斯威夫特，在实践中学习更多。无法确定我的错误。 无论我是编码错误还是实现错误

我正试图在框架的帮助下实现一个主题化特性。 我已经能够更改一些UI元素的颜色，例如

UISegmentedControl

和

UIButton

，但是我无法更改

UITextField

的

borderColor

和

UITableView

的

borderColor以及分隔色。
UITextField
和
UITableView
的颜色更改在相应组件的层上完成。
图层可能是我的问题吗

    func applyTheme(selectedColor: UIColor) {
        Chameleon.setGlobalThemeUsingPrimaryColor(selectedColor, with: .contrast)
        navigationController?.navigationBar.barTintColor = selectedColor
        let contrastingColor = UIColor(contrastingBlackOrWhiteColorOn:selectedColor, isFlat: true)
        navigationController?.navigationBar.titleTextAttributes = [.foregroundColor : contrastingColor]
        saveThemeColors(thmColor: selectedColor, contrastColor: contrastingColor)

    }
    func saveThemeColors(thmColor: UIColor,contrastColor: UIColor)  {
        UserDefaults.standard.set(thmColor, forKey: "themeColor") 
        UserDefaults.standard.set(contrastColor, forKey: "contrastThemeColor")
    }
}
extension UserDefaults {
    func set(_ color: UIColor, forKey key: String) {
        set(NSKeyedArchiver.archivedData(withRootObject: color), forKey: key)
    }
    func color(forKey key: String) -> UIColor? {
        guard let data = data(forKey: key) else { return nil }
        return NSKeyedUnarchiver.unarchiveObject(with: data) as? UIColor
    }
}

在将新值存储到变量后，会立即调用didSet。在您的情况下，变量的didSet没有调用。尝试更新您的主题颜色，ViewWillDisplay或ViewDidDisplay块上的SecondTrastColor

之后，您应该在ViewWillDisplay或ViewDidDisplay中再次调用styleUI（）方法

var themeColor = UIColor.black
var themeContrastColor = UIColor.white

override func viewDidAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    let themeColorData = UserDefaults.standard.value(forKey: "themeColor")
    let contrastColorData = UserDefaults.standard.value(forKey: "contrastThemeColor")

    themeColor = (NSKeyedUnarchiver.unarchiveObject(with: themeColorData as! Data) as? UIColor)!
    themeContrastColor = (NSKeyedUnarchiver.unarchiveObject(with: contrastColorData as! Data) as? UIColor)!

    styleUI()
}

或者，您可以使用代理协议通知您的viewController，而不是使用ViewDidDisplay。
不要使用
var themeColor=UIColor.black
，请尝试使用：

var themeColor: UIColor? {
    didSet {

    }
}
