Question

I create tableView with sections, i use custom cell and define there checkbox(UIImageView) with image in this way:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"cellIdentifier";
    StandardCellWithImage *cell = (StandardCellWithImage *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if(cell == nil) {
        cell = [[StandardCellWithImage alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        cell.selectionStyle = UITableViewCellSeparatorStyleNone;
    }

    cell.checkbox.tag = indexPath.row;
    UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(didSelectedImageAtIndexPath:)];
    tapGesture.numberOfTapsRequired = 1;
    tapGesture.delegate = self;
    [cell.checkbox addGestureRecognizer:tapGesture];
    cell.checkbox.userInteractionEnabled = YES;

    return cell;
}

And in didSelectedImageAtIndexPath method i use:

- (void) didSelectedImageAtIndexPath:(id) sender {
    UITapGestureRecognizer *gesture = (UITapGestureRecognizer *) sender;
    NSIndexPath *indexPath = [NSIndexPath indexPathForRow:gesture.view.tag inSection:0];
}

But i’ve got here only row without any knowledge of on which section user tap this row. Is there any possibility to recognize it?

Answer 1

What about if you encode item/section within view.tag like this:

view.tag = indexPath.section * kMAX_SECTION_SIZE + indexPath.item;

then you could do:

- (void) didSelectedImageAtIndexPath:(id) sender {
  UITapGestureRecognizer *gesture = (UITapGestureRecognizer *) sender;


  NSIndexPath *indexPath = [NSIndexPath indexPathForRow:gesture.view.tag % kMAX_SECTION_SIZE
                                        inSection:int(gesture.view.tag / kMAX_SECTION_SIZE)];
}
