第一次加载时启动屏幕出现离子白屏问题（iOS-ionic3）

好吧，我知道有很多类似的问题，但我面临着一个稍微不同的问题

事实上，当我使用Xcode10为iOS构建Ionic3应用程序时，它构建得非常完美，但当应用程序第一次启动时，它会显示很长时间的启动屏幕，然后白色屏幕会无限期地停留，但如果我最小化应用程序并再次打开，我会看到所有内容都加载良好，应用程序工作正常（我在iOS模拟器和设备上都面临这个问题）

每次我在关闭应用程序的任务后启动应用程序时都会发生这种情况。但在关闭应用程序（而不是清除其任务）并再次打开应用程序后，它工作正常，白色屏幕消失。 虽然没有很好的与白色屏幕相关的解决方案，我几乎尝试了所有方法，但问题仍然存在。请帮助我

PS：同一个应用程序在Android中的调试和生产版本（在模拟器和设备上）都能完美运行

好吧，我找到了确切的问题所在。这是因为在更改iOS平台版本时添加和删除了插件。因此，

设备在加载插件之前没有准备好

要解决此问题，请确保已添加最新的iOS平台。然后开始逐个删除
插件文件夹中的插件


要删除插件，请写入：

爱奥尼亚cordova插件rm

如果它的
npm
模块在那里，那么也卸载它：

npm卸载--保存

确保以这种方式删除每个插件。然后，刷新项目或使用以下命令清理项目：

npm干净运行

然后，再次开始添加插件。使用：

爱奥尼亚科尔多瓦插件添加

npm安装--保存

在此之后，只需使用：

爱奥尼亚cordova构建android--prod

一切都会好起来的

PS：如果在构建过程中出现任何问题，比如，

version 4，预期为3，那么这意味着，您的项目是针对
ionic 3
，因此，在这种情况下，您可能必须更改
@ionic native/core
和
rxjs
版本，然后必须将node_modules/@ionic native

中每个元数据文件的

版本从4更改为3

希望，这将解决您的问题：）
好吧，您的应用程序可能需要很长时间才能加载，因此如果是这样，请确保在应用程序加载之前一直显示启动屏幕，然后在调用
platform.ready（）
时将其隐藏在
app.component.ts
中。
