iOS - another thread needs to send reloadData to the mainthread

Question

I got a separate thread that creates a UIView object, inserts it into the UITableView's data source and then call reloadData on the UITableView. However, since it is a separate thread, it cannot call reloadData directly, it needs to make the mainthread do it... but how do you tell the mainthread to do it?

Thanks

[self.tableView performSelectorOnMainThread:@selector(reloadData)
                                 withObject:nil
                              waitUntilDone:NO];
