在 iOS 12.2 上，我的应用在启动后立即终止，xcode 中显示以下消息:
On iOS 12.2 my app is terminated just after startup, with this message in xcode:
由于未捕获的异常NSUnknownKeyException"而终止应用，原因:[setValue:forUndefinedKey:]:此类不符合键 _alwaysRunsAtForegroundPriority 的键值编码."
Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key _alwaysRunsAtForegroundPriority.'
谁能为我指出正确的方向?我看到之前有一些警告:
Anyone who can point me in the right direction for this one? I see that there has been some warnings about this earlier:
如何解决应用验证问题"应用引用 Payload/MyApp.app/MyApp 中的非公共选择器:_setAlwaysRunsAtForegroundPriority:"?
该帖子的答案是，这是来自 webview 的安全警告，可以忽略.但是当它让我的应用程序崩溃时，它真的不能再被忽视了:)
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 :)
提前感谢您的帮助.

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

在插件中，底部有一个setValue"，可以破坏应用程序.得到了 12.2 的构建.试试
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
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" />
希望至少可以帮助某人进行构建
Hopefully helps someone at least get the build going
