Answer 1

我已经解决了这个问题。安装插件:ionic cordova 插件添加 cordova-plugin-ionic-webview --save并更新 config.xml:

<allow-navigation href="http://localhost:8080/*"/>
<feature name="CDVWKWebViewEngine">
  <param name="ios-package" value="CDVWKWebViewEngine" />
</feature>

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