Question

I have 2 UITableView with UISearchDisplayController on a same UIView.
How to determine which one of the two UITableView relates to the UISearchDisplay Controller?

Welcome any comment

You can set tags both for the searchBars and tableViews, and check them appropriately in the callbacks of UISearchBarDisplayController and UITableView delegates.

For example:

-(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchScope:(NSInteger)searchOption
{
    if (controller.searchBar.tag == 1)
    {
        [self.tableView1 reloadData];
        return YES;
    }
    else if (controller.searchBar.tag == 2)
    {
        [self.tableView2 reloadData];
        return YES;
    }
    return NO;
}

You can always use tags on UIViews to check “who is who” in your code.

Hope this helps.
