我有一个Ionic应用程序，它是用Ionic 3创建的，最近更新为Ionic 5(Angular 8(
该应用程序在Chrome浏览器(带有ionic serve(中运行时没有任何问题，并且一切正常。
近两周来，我一直在尝试制作一个运行iOS的版本
我安装了最新的XCode 12，并尝试使用ionic cordova build ios --prod创建构建。构建完成后，我在xCode中打开项目文件，并尝试在iPhone上进行测试
此时会显示登录屏幕，用户可以通过单击登录按钮进行身份验证。这将打开一个InAppBrowser，用户可以在其中进行身份验证。在成功认证之后，InAppBrowser关闭并且登录的flag被设置为true。
通常，这应该允许在主屏幕中显示一些平铺内容。由于某些原因，页面不会刷新，也不会显示平铺。第一个Rest-request似乎运行良好，在调试主页后，我可以看到用户信息已成功接收。在xCode中，我可以看到一些错误消息：

我的问题是，是什么原因导致了这个错误？提前感谢您的回答。

我确实试图找出导致此问题的代码。我在登录过程中注释了一些可能会导致问题的步骤。
在注释掉InAppBrowser的调用后，我没有看到任何错误。我意识到，我从后端收到的重定向导致了InAppBrowser中的loaderror-事件。这就是为什么"webView:didFailProvisionalNavigation-1004:无法连接到服务器。"错误消息。我的其他代码是从InAppBrowser加载错误事件中调用的，我猜WebView在发生错误后无法处理此问题。
