好吧，我知道有很多类似的问题，但我面临着一些不同的问题。
实际上，当我使用 Xcode10 构建适用于 iOS 的 Ionic3 应用程序时，它构建得非常完美，但是当应用程序第一次启动时，它会显示很长一段时间的启动屏幕，然后白屏会无限期地停留，但是如果我最小化应用程序并再次打开，我看到一切都加载良好并且应用程序工作正常(我在 iOS 模拟器和设备上都面临着这个问题)。
每次我在关闭任务后启动应用程序时都会发生这种情况。但是关闭它(不是为了清除其任务)并再次打开它后，它工作正常并且白屏消失。 尽管没有好的白屏相关解决方案，并且我尝试了几乎所有方法，但问题仍然存在。请帮我。
PS:同一个应用程序在 Android 中的调试和生产版本中都能完美运行(在模拟器上以及在设备上)。

最佳答案
好吧，我找到了确切的问题。这是由于iOS平台版本变更时插件的添加和删除造成的。因此device doesn't get ready before loading plugins .
要解决此问题，请确保您已添加最新的 iOS 平台。然后开始一一删除 plugins folder 中的插件.
要删除插件，请编写:
ionic cordova plugin rm <plugin-name>
如果是 npm模块在那里，然后也将其卸载:
npm uninstall --save <plugin-name>
确保以这种方式删除每个插件。然后，刷新您的项目或使用以下命令清理项目:
npm run clean
然后，再次开始添加插件。用途:
ionic cordova plugin add <plugin-name>
npm install --save <plugin-name>
之后，只需使用以下命令再次构建项目:
ionic cordova build android --prod
一切都会正常进行。 :)
PS:如果构建时出现任何问题，如 version 4 present, expected 3 ，那么这意味着，您的项目是为 ionic3 制作的，因此，在这种情况下，您可能必须更改 @ionic-native/core和rxjs版本，然后必须更改 version from 4 to 3 in every metadata file in node_modules/@ionic-native 。
希望这能解决您的问题:)
