How do I retrieve UITableView row number of a UISwitch?

Question

I have tried several approaches posted here, but I cannot get my table full of switches to return an index value for the cell of the changed switch. I am creating the view c

You may set switch view tag to row index. Instead of theSwitch.tag = 100;

do

-(UITableViewCell*)tableView:table cellForRowAtIndexPath:indexPth
{
    UISwitch *theSwitch = nil;
    if (cell == nil) {
        ...
        // as per your example
        [cell.contentView addSubview:theSwitch];
    } else {
        theSwitch = subviewWithClass(cell.contentView, [UISwitch class]);
    }

    theSwitch.tag = indexPath.row;
    ...
}

Add this helper function to replace viewWithTag: call

UIView *subviewWithClass(UIView *contentview, Class klass)
{
    for (UIView *view in contentview.subviews)
        if ([view isKindOfClass:klass])
            return view;
    return nil;
}

Then retrieve tag, that is a row index now, in your switchChanged function

-(IBAction)switchChanged:(UISwitch *)sender {
    NSLog(@"Selected Switch - %d", sender.tag);
    ...
 }
