UIStepper in uitableviewcell

Question

In my app I have custom UITableViewCell, and I have UIStepper and UILabel in the custom cell. I don't know how to check which stepper was clicked. So is it a way to know from which cell stepper was clicked?

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell;
    NSString *CellIdentifier = @"Cell";
    cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil];
        if ([nib count] > 0) {
            cell = self.tbcell;
        }
    }
    return cell;
}

UITableViewCell *cell; NSString *CellIdentifier = @"Cell"; cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil]; if ([nib count] > 0) { cell = self.tbcell; } } return cell; — Dmitriy Kalachniuk, Mar 18 '12 at 19:32

An alternative is:

In the method that gets fired when the UIStepper value changes (e.g. @max_, above), you can do the following:

- (IBAction)stepperValueDidChanged:(UIStepper *)sender {
    UITableViewCell *cell = (UITableViewCell *)[[sender superview] superview];
    // assuming your view controller is a subclass of UITableViewController, for example.
    NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
}

+1 much better than setting the tag to the row index because it works for sectioned tables too. and it doesn't rely on state saved in the view – Matthias Bauch Mar 18 '12 at 20:04
I understand that this does not work in IOS 7. Can anyone suggest an IOS 7 solution? – Mc.Stever Apr 19 '14 at 16:41
It works in IOS if you use [[[sender superview] superview] superview] – Mc.Stever Apr 19 '14 at 17:16

[step addTarget:self action:@selector(someAction:) forControlEvents:UIControlEventValueChanged];

- (void) someAction:(UIStepper *) stepper {
    NSLog(@"stepper clicked");
}
