White blank screen issue with cordova ios with cordova-plugin-ionic-webview or cordova-plugin-wkwebview-engine plugins

Question

There will an issue with UIWebview in ios. Apple is going to reject app using this. So we decided to use WKWebview for our cordova ios app. I installed cordova-plugin-wkwebview-engine and added <preference name="WKWebViewOnly" value="true" /> in config.xml file. The issue is after the splash screen Its showing white blank screen.

Answer 1

remember to add this plugins:

<plugin name="cordova-plugin-wkwebview-engine"  source="npm" /> 
<plugin name="cordova-plugin-wkwebview-file-xhr"  source="npm" /> 

and add this

<preference name="WKWebViewOnly" value="true" />
<feature name="CDVWKWebViewEngine">
    <param name="ios-package" value="CDVWKWebViewEngine" />
</feature>
<preference name="CordovaWebViewEngine" value="CDVWKWebViewEngine" />
<preference name="AllowBackForwardNavigationGestures" value="true" />
<preference name="Allow3DTouchLinkPreview" value="false" />

To build it with [email protected]+

• remove splash plugin (now is integrated)
• upgrade the inappbrowser plugin to v4.0.0
• remove all wkwebview related plugins
• add scheme and host to config.xml:

    <preference name="scheme" value="app" />
    <preference name="hostname" value="localhost"  />
