Sending location coordinates to server in background from iOS

Question

I am developing an app which needs to send user location to server. I have to update user location every second and send it to server from background.

I am able to fetch the location co ordinates in background, but how can I send this to sever in every second ? Please help me.

I found this is working in an app - UBER

It depends on what is your server expecting to be sent. But here is an example using AFNetworking 2.0:

- (void)sendLocation:(CLLocationCoordinate2D)coordinate
{
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

    NSDictionary *parameters = @{
                                 @"latitude": [NSNumber numberWithDouble:coordinate.latitude],
                                 @"longitude": [NSNumber numberWithDouble:coordinate.longitude]
                                 };

    [manager POST:@"http://example.com/yourendpoint"
       parameters:parameters
          success:^(AFHTTPRequestOperation *operation, id responseObject)
    {
        NSLog(@"JSON: %@", responseObject);
    }
          failure:^(AFHTTPRequestOperation *operation, NSError *error)
    {
        NSLog(@"Error: %@", error);
    }];
}

Sending user location every second is not a good idea. You should rather send it when it changes or in longer time intervals.

Hope it helps.
