//when the application is about to move from active to inactive state.

- (void)applicationWillResignActive:(UIApplication *)application
{
    [self sendBackgroundLocationToServer];
}


- (void) sendBackgroundLocationToServer
{
UIBackgroundTaskIdentifier bgTask = UIBackgroundTaskInvalid;
bgTask = [[UIApplication sharedApplication]
          beginBackgroundTaskWithExpirationHandler:^{
              [[UIApplication sharedApplication] endBackgroundTask:bgTask];
          }];


//Start Timer
[self startTimer];

//Close the task
if (bgTask != UIBackgroundTaskInvalid)
{
    [[UIApplication sharedApplication] endBackgroundTask:bgTask];
}
}
