Reload UITableView data and not the visible cells

I'm working on an app where I want to pull data from a remote web service and populate a UITableView. When I get new data I want the currently visible cells to remain and add the new data above it, much like most Twitter clients does. My load method currently looks like this:

- (void)loadPostsInBackground
{
    NSURL *url = [NSURL URLWithString:@"[URL]"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    AFJSONRequestOperation *operation;
    operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id jsonObject) {

        [self createPostsFromDict:jsonObject];
        [self.refreshControl endRefreshing];
        [self.tableView reloadData];

    } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id jsonObject) {

        NSLog(@"Received an HTTP %d", response.statusCode);
        NSLog(@"The error was: %@", error);

    }];

    [operation start];

}

This works, but it updates the currently visible cells with the new data. So what I want is, get new data, add it above the currently visible cells (or stay at the currently visible cells). What is the best way to do this?

Note: I will require iOS6.

Instead of calling reloadData on the table view. You should call insertRowsAtIndexPaths:withRowAnimation:. Do that after updating the data used by the table view's data source.
