var viewColor:KKColorListViewController!
  viewColor = KKColorListViewController(schemeType:KKColorsSchemeType.crayola)
  viewColor.delegate = self
  //选择颜色后走的回调
  func colorListController(_ controller:KKColorListViewController,  didSelect color:KKColor)
    {
        viewColor.dismiss(animated: true, completion:nil)
        alertColor = color
        self.view.backgroundColor = alertColor.uiColor()
    }
    //用户在颜色选择器视图里点击了关闭
    func colorListPickerDidComplete(_ controller:KKColorListViewController)
    {
        viewColor.dismiss(animated: true, completion:nil)
    }

SwiftMessage 是一个很方便的弹出框

提供四种样式选择有多种属性设置，我这里显示出最常用的样式和最简单的方法，我在宏文件里面进行封装然后一句代码调用。

func showAlert(theme:Theme,message:String){
 let alert = MessageView.viewFromNib(layout: .messageView)
 alert.configureTheme(theme)
 
 alert.configureDropShadow()
 alert.configureContent(title: "提示", body: message)
 alert.button?.isHidden = true
 var cofing = SwiftMessages.defaultConfig
 cofing.presentationContext = .window(windowLevel: .alert)
 SwiftMessages.show(config: cofing, view: alert)   
}
//调用方法
@IBAction func showAlert(_ sender: Any) {

     
     MVVM.showAlert(theme: Theme.warning, message: textFile.text ?? "")

 }
 @IBAction func infoAlert(_ sender: Any) {
     MVVM.showAlert(theme: Theme.info, message: textFile.text ?? "")

 }
 @IBAction func errorAlert(_ sender: Any) {
     MVVM.showAlert(theme: Theme.error, message: textFile.text ?? "")

 }
 @IBAction func successAlert(_ sender: Any) {
     MVVM.showAlert(theme: Theme.success, message: textFile.text ?? "")

 }

上面两个库还是很好用的，日常开发中会经常用到，后续持续更新好用而且常用的第三方库
