identifying Button selection of each row in Tableview?

Question

hi,i coded like

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

    UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    btn.frame = CGRectMake(230.0f, 4.0f, 60.0f, 36.0f);
    [btn setTitle:@"OK" forState:UIControlStateNormal];
    [btn setTitle:@"OK" forState:UIControlStateSelected];
    [btn addTarget:self action:@selector(onClickRename:) forControlEvents:UIControlEventTouchUpInside];
    [cell addSubview:btn];

    return cell;

}

but if the user selects the button on particular row, i can change that image through onClickRename...but can i get inwhich row's image has been touched through

• (void)tableView:(UITableView )tableView didSelectRowAtIndexPath:(NSIndexPath)indexPath ?

Answer 1

you could do something like

[btn setTag:[indexPath] row]

in your cell setup, and then

- (void) onClickRename:(id)sender {
    int row = sender.tag;
}

you'd know which table row was hit.

Apple uses the following technique in their Accessory sample code:

- (void)checkButtonTapped:(id)sender event:(id)event
{
    NSSet *touches = [event allTouches];
    UITouch *touch = [touches anyObject];
    CGPoint currentTouchPosition = [touch locationInView:self.tableView];
    NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint: currentTouchPosition];
    if (indexPath != nil)
    {
        // do what you want with the item at indexPath
    }
}
