我正在构建一个在后台运行的应用程序，并在设备上跟踪大量位置更改。
是否可以将推送通知发送到设备，并让设备将当前的精确位置发送到服务器，而无需用户打开应用程序，以便在前景中运行？
此上一个所以答案似乎不再使用ios15。 应用程序：DidreceivereMoteNotification：FetchCompletionHandler 在我预先登上应用程序之前，似乎才被调用。有一种新方法可以实现此功能吗？
I'm building an app which is running in the background and tracking significant location changes on the device.
Is it possible to send a push notification to the device and have the device send the current precise location to a server without needing the user to open the app so it runs in the foreground?
This previous SO answer doesn't seem to work anymore with iOS15. application:didReceiveRemoteNotification:fetchCompletionHandler does not seem to get called until I foreground the app. Is there a new method to achieve this functionality?

有一个新功能以来iOS 15 ：位置推动服务扩展（cllocationPushServiceExtension -docs 在这里）。这是一种在iOS设备上查询位置的电力有效方法，即使您的应用不运行，也是如此。
请深入研究文档，并按照步骤配置Xcode项目，添加位置推动服务扩展目标并实现位置推动功能。不要忘记适当的权利，并要求授权位置服务！
There is a new feature since iOS 15: Location Push Service Extension (CLLocationPushServiceExtension - docs here). It is a power efficient way to query locations on iOS devices, even when your app isn’t running.
Please dive in into the docs and follow steps to configure Xcode project, add a Location Push Service Extension Target and implement Location Push functionality. Don't forget about proper entitlements and to request authorization for Location Services!
