reload cell data in table view with Swift

问题

how is it possible to reload data for a cell in my table view? I want to do a request to my Server and the server responses JSON. At the moment I implemented the request and the response handling and I can show the data in my cells. But I want that the server only responses maybe ten datasets. When I scroll to the end of the table view with my ten cells in the app I want to do the next request to my server and the server delivers the next ten datasets and so on. I work with Swift as the programming language.

THX!

You can use self.tableView.reloadData() in order to reload your entire table or self.tableView.reloadRowsAtIndexPaths(paths, withRowAnimation: UITableViewRowAnimation.None) in order to reload a specific cell.

dispatch_async(dispatch_get_main_queue(), { () -> Void in
   self.tableView.reloadData()
})
