cordovakatzer插件背景模式不适用于iOS-9
在我的离子/ angularjs应用程序我使用https://github.com/katzer/cordova-plugin-background-mode/为背景我的应用程序。
它在iOS-8上工作安静，但新的iOS-9不能再工作了。 我做了一些testing，看起来应用程序真的在后台工作，但用户没有得到任何信息。 在iOS-8上，我收到一条消息，如“YourApp正在使用您的位置”或类似的东西在显示器上。 在iOS-9上，此消息缺失。
有人对这个插件有相同的经验吗？
我发现iOS9的核心位置函数有一些变化： iOS9的CLLocationManager中的allowBackgroundLocationUpdates
就像在这篇文章中提到的那样，我在org.apache.cordova.geolocation插件中添加一个默认属性allowBackgroundLocationUpdates，其值为YES。
在位于/plugins/org.apache.cordova-geolocation/src/ios/ CDVLocation.m中使用此修补程序，现在可以工作。
为了使它工作，我删除了与cordova platform remove ios平台ios cordova platform remove ios ，并再次与cordova platform add ios回来，所以它build立了新的插件。
现在我再次看到显示器上的蓝条:-)
此修复将打破iOS <9.0的地理位置支持。 要使用比9.0更旧的版本，请使用以下CDVLocation.m文件：

感谢您更新地理位置插件，以便它允许应用程序在iOS 9的后台运行。
我花了相当长的一段时间才把这一切工作在Phonegap Build应用程序中。 看看我需要在我的config.xml文件中包含什么可能会有所帮助：
