升级到 WKWebView Ionic 3 后 iOS 应用程序启动后出现白屏

Question

我已通过关注 this 博客将我的应用程序升级到 WKWebView。如果我使用 ionic cordova build ios 进行构建，它会正常运行，但是如果我进行 --prod 构建，那么我的应用程序会在启动画面和出现白屏后卡住。我已经阅读了很多关于相同主题的帖子并发现了类似的问题。

我试过以下插件 -

ionic cordova plugin add cordova-plugin-ionic-webview --save
, cordova plugin add cordova-plugin-wkwebview-engine, cordova plugin add cordova-plugin-wkwebview-file-xhr

但问题依然存在

这是我的 config.xml-

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

    </platform>

如何进行这项工作？非常感谢您的帮助，因为 2 天以来我一直被这个问题困扰。

谢谢！

Answer 1

经过一番折腾，我发现问题在生产版本上有所不同。由于 Typescript 版本不匹配导致空白屏幕，我收到 cannot find module '.' 错误。当我降级 TS 版本时，我能够进行产品构建。

以后遇到同样问题的人发帖。

谢谢！
