问题描述
最初，我们使用有角度的cordova-ios版本4.5.4，并将IPA上载到Apple Store Connect时出现UIWebView错误，因此将cordova-ios平台升级到5.1.1并添加了cordova-plugin-wkwebview-engine插件。现在，在生成IPA时，它将显示空白屏幕，并且不会路由到登录屏幕。
版本详细信息如下：
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
我们使用以下命令进行构建：
ng build --prod --source-map=false && cordova build ios

解决方法
不幸的是，白屏错误非常普遍，因为控制台中未列出错误条件（请参见Cordova - white screen after splash,no exceptions in console）。
但是，您可以在iOS模拟器中启动该应用程序并将其连接到Safari的开发工具，然后单击刷新。它应该排除iOS正在运行的异常。
