How to properly use location in background - app got rejected 3 times

Question

My app got rejected by Apple three times, all with the same rejection letter, which is:

We found that your app uses a background mode but does not inc

Answer 1

This question is old and already answered but you dont need the UIBackgroundModes key if you collect locations using the startMonitoringSignificantLocationChanges API

Answer 2

startMonitoringSignificantLocationChanges don't require a background mode registration. Only continuous location changes do.

Answer 3

In locationManager:didUpdateToLocation:fromLocation: or in updateMyLocationToServer: You should check if application is in background state by eg.

[UIApplication sharedApplication].applicationState == UIApplicationStateBackground

And then if Your app is in background mode You should use eg.

backgroundTask = [[UIApplication sharedApplication]
                    beginBackgroundTaskWithExpirationHandler:
                    ^{
                        [[UIApplication sharedApplication] endBackgroundTask:backgroundTask];
                    }];

/*Write Your internet request code here*/

if (bgTask != UIBackgroundTaskInvalid)
{
    [[UIApplication sharedApplication] endBackgroundTask:backgroundTask];
    bgTask = UIBackgroundTaskInvalid;
}

This way application should perform this task completely.
