gistfile1.m

-(void)locationManager:(CLLocationManager *)manager didFinishDeferredUpdatesWithError:(NSError *)error {
    NSLog(@"%s -- error: %@", __PRETTY_FUNCTION__, error);
    _deferring = NO;
}

    [self.tableView reloadData];
}

    NSLog(@"%s", __PRETTY_FUNCTION__);
}

-(void)locationManagerDidResumeLocationUpdates:(CLLocationManager *)manager {
    NSLog(@"%s", __PRETTY_FUNCTION__);
}

-(BOOL)locationManagerShouldDisplayHeadingCalibration:(CLLocationManager *)manager {
    return YES;
}

- (void)enterringBackground {
    NSLog(@"%s", __PRETTY_FUNCTION__);
    if (![CLLocationManager deferredLocationUpdatesAvailable]) {
        NSLog(@"NO DEFERRED LOCATION AVAILABLE");
        return;
    }
        
    if (!_deferring) {
        NSLog(@"Deferred location available");
        [self.locationManager allowDeferredLocationUpdatesUntilTraveled:CLLocationDistanceMax timeout:CLTimeIntervalMax];
        _deferring = YES;
    }
}

- (void)enterringForeground {
    NSLog(@"%s", __PRETTY_FUNCTION__);
    [self.tableView reloadData];
}
