iOS: UITabelView - didSelectRowAtIndexPath is not called

I had come across a problem which didSelectRowAtIndexPath doesn’t execute when I tap the cell.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSLog(@"Successfully tapped");
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
}

No matter how I tap, it doesn’t show the log.

As shown in the attribute inspector, the Selection is not none, User Interaction Enabled is also checked.

Finally, I found the problem…

- (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    return nil;
}

I forgot to remove willSelectRowAtIndexPath in ViewController.
