Answer 1

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.
