title: NSCFConstantString objectAtIndex unrecognized selector sent to instance
body: <p>I am getting the above mentioned error and do not know why because I implemented the same code in another example. "services" is my NSMutableArray and "service name" is the label on table view with Tag 2. In viewdidload I fill the service array with objects. </p>
  
  <pre><code>-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
  {
      NSString *cellIdentifier = @"servicesCell";
      UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
      UILabel *servicesName;
      UILabel *nrofService;
      if(tableView == self.servicetable)
      {
          servicesName = (UILabel*) [cell viewWithTag:2];
          servicesName.text = [[services objectAtIndex:0] objectAtIndex:indexPath.row];            
      }
      return cell;
  }
  </code></pre>
