科尔多瓦WKWebView白屏

Question

我试图让我的iPhone上的Cordova内部运行一个简单的JavaScript应用程序。 项目在模拟器内完美运行，但在手机上运行时显示奇怪的屏幕。

这是我的config.xml文件：

<widget 
  id="com.landonschropp.tictactoe" 
  version="1.0.0" 
  xmlns="http://www.w3.org/ns/widgets" 
  xmlns:cdv="http://cordova.apache.org/ns/1.0">

  <name>Tic-Tac-Toe</name>
  <description>An awesome little tic-tac-toe game.</description>
  <author email="schroppl@gmail.com" href="https://landonschropp.com">Landon Schropp</author>

  <content src="http://localhost:8080" />
  <access origin="*" />
  <allow-navigation href="http://localhost:8080/*" />

  <feature name="CDVWKWebViewEngine">
    <param name="ios-package" value="CDVWKWebViewEngine" />
  </feature>

  <preference name="CordovaWebViewEngine" value="CDVWKWebViewEngine" />

  <plugin name="cordova-plugin-statusbar" spec="^2.2.3" />
  <plugin name="cordova-plugin-whitelist" spec="^1.3.2" />
  <plugin 
    name="cordova-plugin-wkwebview-engine" 
    spec="git+https://github.com/driftyco/cordova-plugin-wkwebview-engine.git" />

  <engine name="ios" spec="^4.4.0" />
</widget>

和我的package.json文件：

  }
}

要构建并运行应用程序，我会执行以下操作：

1. yarn install
2. cordova platform add ios
3. cordova run ios

目前，在手机上运行应用时，我会看到以下屏幕：

正如dymv所提到的，问题很可能是你的应用无法访问localhost，因为＆＃34; localhost＆＃34;在这种情况下，你的开发计算机，而不是iPhone。您可以将其部署到托管服务器解决方案并重新测试吗？

WKWebView插件不是本地服务器，而是增强的WebView组件（WebView基本上是一个运行HTML，CSS，JavaScript代码的应用程序中的嵌入式浏览器）。核心好处是它可以更快地处理JavaScript（更快！），因此您的应用程序将表现更好。
