POuitabelview custom button tag issue

Body
copied!<p>I am creating a custom button in my uitable and giving the button a tag number as shown in code below.</p> <pre><code>// Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { //NSLog(@"Inside cellForRowAtIndexPath"); static NSString *CellIdentifier = @"Cell"; // Try to retrieve from the table view a now-unused cell with the given identifier. UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; // If no cell is available, create a new one using the given identifier. if (cell == nil) { // Use the default cell style. cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]; button = [UIButton buttonWithType:UIButtonTypeCustom]; [button addTarget:self action:@selector(selectPicOnBtnTouch:) forControlEvents:UIControlEventTouchDown]; [button setTitle:@"btn1" forState:UIControlStateNormal]; button.frame = CGRectMake(6.0f, 0.0f, 97.0f, 110.0f); button.tag = (indexPath.row)+100; [cell addSubview:button]; [button setImage:[UIImage imageNamed:@"sample_pic.png"] forState:UIControlStateNormal]; } else { //NSLog(@"went here 2"); button = (UIButton *) [cell viewWithTag:((indexPath.row)+100)]; } //Get an arrow next to the name cell.accessoryType = UITableViewCellAccessoryNone; return cell; } - (IBAction) selectPicOnBtnTouch:(id)sender { button = (UIButton *)sender; NSLog(@"[button tag]: %d ...", [button tag]); } </code></pre> <p>If I have a table with 10 rows and when I touch buttons in rows 1-5 I get the following in my log</p> <pre><code>[button tag]: 100 ... [button tag]: 101 ... [button tag]: 102 ... [button tag]: 103 ... [button tag]: 104 ... </code></pre> <p>This is fine. The problem is that when I touch row 6-10 I am expecting 105 - 109 tags but what I get back is same tag numbers starting over </p> <pre><code>[button tag]: 100 ... [button tag]: 101 ... [button tag]: 102 ... [button tag]: 103 ... [button tag]: 104 ... </code></pre> <p>The reason I want to keep the tag numbers unique (and not repeating) is so that I know which button corresponds to what row. How can I do that? </p>
