Ionic 4 iOS-WKWebViewConfiguration setURLSchemeHandler：forURLScheme：]：无法识别的选择器已发送到实例

时间：2019-07-12 07:06:59

标签： ios xcode cordova ionic-framework

我已将Ionic应用程序移植到Ionic4。为此，我创建了一个新的Ionic应用程序，并一个接一个地重新添加了代码，程序包和插件，以便所有内容都保持最新。

我快到了，但是在iOS上运行时遇到了问题。当我启动该应用程序时，我只是停留在启动屏幕上。在Xcode中运行时，出现标题中的错误。

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[WKWebViewConfiguration setURLSchemeHandler:forURLScheme:]: unrecognized selector sent to instance 0x165b62a0'

发生这种情况时，xcode中的完整调用堆栈为

有些挖掘，似乎与网络视图有关。我尝试了here的建议，但<allow-navigation href="http://localhost:CUSTOM_PORT_NUMBER/*"/>

除外

在我的Ionic 3版本中，我已经安装了cordova-plugin-wkwebview-engine，但是到目前为止，我还没有将其安装到Ionic 4中，并且据我所知，该Web视图现在默认包括在内。

所以我现在在config.xml中没有以下内容... 

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

我当前的config.xml内容如下...

我这里没有<allow-navigation href="http://localhost:CUSTOM_PORT_NUMBER/*"/>，因为这给我造成了窗口存储问题。.它一直被拒绝，直到我将其删除（也许可以安全地放在<platform name="ios">部分中，如果需要的话）

那么，有人对我可以解决此问题有任何想法吗？

我能正确安装Ionic 4的cordova-plugin-wkwebview-engine吗？

在此先感谢您的帮助！

[EDIT1]

更多信息。让xcode打破异常，我可以看看是否来自这里。...

我已将部署目标设置为10.0 例如，在config.xml中，我尝试使用似乎只能更新到ios 10.3的旧版iPhone时设置了<preference name="deployment-target" value="10.0" />。

是不是ios 11.0现在是我们可以支持的最低版本？
