ios - 更新 Angular cordova-ios 平台后，IPA 中出现空白屏幕

Question

最初我们使用 Angular cordova-ios 版本为 4.5.4，在将 IPA 上传到 Apple Store Connect 时，出现了 UIWebView 错误，因此将 cordova-ios 平台升级到 5.1.1 并添加了 cordova-plugin-wkwebview-engine插入。现在生成 IPA 时，它显示空白屏幕并且不会路由到登录屏幕。

版本详情如下:

angular-devkit/architect         0.10.7
@angular-devkit/build-angular     0.10.7
@angular-devkit/build-optimizer   0.10.7
@angular-devkit/build-webpack     0.10.7
@angular-devkit/core              7.0.7
@angular-devkit/schematics        0.8.9
@angular/cli                      6.2.9
@ngtools/webpack                  7.0.7
@schematics/angular               0.8.9
@schematics/update                0.8.9
rxjs                              5.5.12
typescript                        2.9.2
webpack                           4.19.1
cordova-ios                       5.1.1

我们使用以下命令来构建:

ng build --prod --source-map=false && cordova build ios

我们的 config.xml 文件

不幸的是，白屏错误非常常见，因为错误条件未在控制台中列出(请参阅 Cordova - white screen after splash, no exceptions in console )。

但是，您可以在 iOS 模拟器中启动应用程序并将其连接到 Safari 的开发工具，然后点击刷新。它应该会排除 iOS 遇到的异常。
