由于“ _alwaysRunsAtForegroundPriority”，iOS 12上的离子应用程序崩溃 [英] Ionic app crashes on iOS 12.2 because of '_alwaysRunsAtForegroundPriority'
问题描述
在iOS 12.2上，我的应用程序在启动后立即终止，并在xcode中显示以下消息：
由于未捕获的异常'NSUnknownKeyException，正在终止应用程序'，原因：'[setValue：forUndefinedKey：]：此类不适用于_alwaysRunsAtForegroundPriority键的键值编码。'
任何人都可以为我指出正确的方向吗？我发现之前对此有一些警告：
如何解决应用程序验证该应用程序在Payload / MyApp.app /中引用了非公共选择器MyApp：_setAlwaysRunsAtForegroundPriority：？
该帖子的答案是，它是来自webview的安全警告，可以忽略。但是当它使我的应用崩溃时，它真的不能再被忽略了：）
在此先感谢您的帮助。

2019年2月2日更新：看起来是导致错误的cordova-plugin-background-mode。但是我必须承认我不知道如何解决这个问题。当我从项目中删除该插件时，它可以工作。但是我需要该插件，或者至少需要后台模式功能，所以我需要以某种方式修复它。
2019年2月5日更新：
@coderroggie：
我也有cordova-的2.3.2版本plugin-ionic-webview插件。
奇怪的是，它仅在删除cordova-plugin-background-mode（0.7.2版）时才对我有用。
我将发布我的离子信息，如果可以为您提供任何有用的信息。

在插件中，底部有一个 setValue，该值会改变应用程序。得到了一个用于12.2的构建。尝试
ionic cordova插件添加https://github.com/iowayankee/cordova-plugin-background-mode.git
package.json
cordova-plugin-background-mode： git + https：//github.com/iowayankee/cordova-plugin-background-mode.git，
config.xml
< plugin name = cordova-plugin-background-mode spec = git + https：//github.com/iowayankee/cordova-plugin-background-mode.git />
希望至少能帮助某人顺利进行
On iOS 12.2 my app is terminated just after startup, with this message in xcode:
Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key _alwaysRunsAtForegroundPriority.'
Anyone who can point me in the right direction for this one? I see that there has been some warnings about this earlier:
The answer to that post is that it's a security warning from webview that can be ignored. But when it's crashing my app, it can't really be ignored anymore :)
Thanks in advance for any help.

Update Feb 2nd 2019: It looks like it's the cordova-plugin-background-mode that causes the error. But i must admit that i have no idea how to fix that. It works when i remove that plugin from my project. But i need that plugin, or at least the background-mode functionality, so i need to fix this, somehow.
Update Feb 5th 2019: @coderroggie: I also have the version 2.3.2 of the cordova-plugin-ionic-webview plugin. It's strange that it works for me only when removing the cordova-plugin-background-mode (version 0.7.2)
I'll post my ionic info, if that can provide you with any helpful information.
Ionic:

In the plugin there's a 'setValue' towards the bottom that nukes the app. Got a build going for 12.2. Try
ionic cordova plugin add https://github.com/iowayankee/cordova-plugin-background-mode.git
package.json
"cordova-plugin-background-mode": "git+https://github.com/iowayankee/cordova-plugin-background-mode.git",
config.xml
<plugin name="cordova-plugin-background-mode" spec="git+https://github.com/iowayankee/cordova-plugin-background-mode.git" />
Hopefully helps someone at least get the build going
