Does location update remain running after force close app

Question

I am sending user location at n time on server for tracking. Working fine in foreground and background mode. But my question is bit more theoretical.. Does my location update service remain running after i force close the app on the device?

I know i can check it on server, But sorry i don't have server access permission. So i have to be sure in which scenario my location service will stop running.

Answer 1

Yep it will continue to be updated when the application is sent into the background. For some official docs check here under the "Getting Location Events in the Background (iOS Only)" section.

Also, under special circumstances you can register your application to have a true background process running like Android allows. So when the user kills the background application, your app doesn't really die. The background process continues to work. Apple will only allow apps that have a necessary reason for this though. Such as a turn by turn navigation app (example from the docs).

Answer 2

Yes, if the application is removed from background then location update will be stopped.

Answer 3

iOS will only restart an app after a force close if its uses region monitoring or the significant-change location service. From the iOS Location and Maps Programming Guide section on Getting the User’s Location:

If your app is terminated either by a user or by the system, the system doesn’t automatically restart your app when new location updates arrive. A user must explicitly relaunch your app before the delivery of location updates resumes. The only way to have your app relaunched automatically is to use region monitoring or the significant-change location service.

iOS only restarts the app if it has Background App Refresh enabled:

when a user disables the Background App Refresh setting either globally or specifically for your app, the system doesn’t relaunch your app for any location events, including significant-change or region monitoring events.
