Cordova katzer插件后台模式在iOS-9上不工作

在我的ionic/angularjs应用程序中，我使用它作为应用程序的背景

它在iOS-8上运行得很好，但在新的iOS-9上就不再工作了。我做了一些测试，它看起来像是真正的应用程序在后台工作，但用户没有得到有关它的信息。在iOS-8上，我会在屏幕上方收到一条类似“YourApp正在使用您的位置”之类的消息。在iOS-9上，此消息丢失

---

有没有人使用过这个插件

我发现iOS9上的核心位置函数有一些变化：

就像在文章中建议的那样，我在org.apache.cordova.geolocation插件中添加了一个默认属性allowsBackgroundLocationUpdates，其值为YES

使用位于

/plugins/org.apache.cordova geolocation/src/ios/

中的CDVLocation.m上的此修复程序，它现在可以工作了

为了让它发挥作用，我用

cordova platform remove ios

删除了平台ios，然后用

cordova platform add ios

重新添加了它，这样它就可以构建新的插件

现在我又看到了显示屏上的蓝色条：-）

此修复程序将破坏iOS<9.0上的地理位置支持。要使其适用于9.0以上的旧版本，请使用此CDVLocation.m文件：
