代码适配

获取当前的模式

 UITraitCollection.current.userInterfaceStyle

判断是否是暗黑模式

 if UITraitCollection.current.userInterfaceStyle == .dark {
      //暗黑模式
} else {
      //其他模式
}

监听显示模式的改变方法

    override func traitCollectionDidChange(_ previousTraitCollection: UITraitCollection?) {
        super.traitCollectionDidChange(previousTraitCollection)
        if #available(iOS 13.0, *) {
//是否改变
            if self.traitCollection.hasDifferentColorAppearance(comparedTo: previousTraitCollection) {
                //不同
                if self.currentStyle == false {
                    self.view.backgroundColor = .black
                    self.lbl?.text = "Dark"
                    self.lbl?.textColor = .white
                } else {
                    self.view.backgroundColor = .white
                    self.lbl?.text = "Light"
                    self.lbl?.textColor = .black
                }
                self.currentStyle = !self.currentStyle
            }
        } else {
            // Fallback on earlier versions
        }
    }
