title: Exception when load table containing data from sqlite3
body: <p>I'm developing iPhone app , I created a view controller that contains a button and tableViewController that must show the data form sqlite3 , I'm using xcode 3.4 
  I want the button that in viewController open the TableViewController , when I try to open that table itself without button I go to the storyboard and put the raw on the TableViewController and it loads the data of sqlite normally 
  but when I put the raw on the viewController and connect the button to the TableViewController and make the connection modal then run .. when I press the button, it gives me the following Exception: 
  <code>NSInvalidArgumentException', reason: '-[NSIndexPath isEqualToString:]: unrecognized selector sent to instance ...</code></p>
  
  <p>and the exception refers to a line in (<code>cellForRowAtIndexPath</code>)</p>
  
  <p>here is my code :</p>
  
  <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
  {
  static NSString *CellIdentifier = @"Cell";
  UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
  
  if (cell == nil) {
      cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
  }
  
  Books *temp= (Books *)[self.books objectAtIndex:indexPath.row];
  
  
  // [cell setText:temp.bo_name];
  [cell setText:[NSString stringWithFormat:@"%d - %@ - %d - %d - %d - %d - %@ - %f - %f - %@ - %f - %d - %@ - %d",temp.bo_id, temp.bo_name, temp.bo_au_id, temp.bo_pub_id, temp.bo_num_pages, temp.bo_publish_year, temp.bo_about, temp.bo_price, temp.bo_currency, temp.bo_cover_img, temp.bo_recomended, temp.bo_sec_id, temp.bo_path, temp.bo_sort]];
  
  return cell;
  
  }
  </code></pre>
