Nativescript iOS UIColor

Question

我想在 Nativescript 中将 NavigationBar/ActionBar 颜色设置为 Transparent/Clear。

import {BasePage} from "../../shared/BasePage";
import frameModule = require("ui/frame");
import {topmost} from "ui/frame";
import {Observable, EventData} from "data/observable";
import {View} from "ui/core/view";

class HomePage extends BasePage{

   mainContentLoaded(args:EventData){
       let view = <View>args.object;

       if(view.ios){
          var controller = frameModule.topmost().ios.controller;
          controller.navigationBar.barTintColor = UIColor.redColor();
       }

       view.bindingContext = new Observable({ myText: 'This is the home page' });
   }
}
   export = new HomePage();

但是我得到这个错误："error TS2304: Cannot find name 'UIColor'"

我做错了什么？

感谢帮助

我建议你使用 NS 颜色模块并将其转换为 iOS 颜色，这样你就可以使用任何你想要的颜色。像这样：

var colorModule = require("color");
var red = new colorModule.Color("#ff0000");

var controller = frameModule.topmost().ios.controller;
controller.navigationBar.barTintColor = red.ios;
