How to know the UITableview row number

Question

I have a UITableViewCell with UISwitch as accessoryview of each cell. When I change the value of the switch in a cell, how can I know in which row

Answer 1

A colleague suggested the following, which I made into a UITableView category:

+(UITableViewCell*)findParentCellForSubview:(UIView*)view
{
    while (([view isKindOfClass:[UITableViewCell class]] == NO) && ([view superview] != nil))
        view = [view superview];

    if ([view superview] != nil)
        return (UITableViewCell*)view;

    return nil;
}

Still hackly - but it works.
