  <p>i have tried it at the top of the tableview and it worked but i dont know how can i add it below the tableview. here is some sample code..</p>
  
  <pre><code>      - (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView {
  if (isLoading) return;
  isDragging = YES;

  refreshLabel.textAlignment = UITextAlignmentCenter;
  
  refreshArrow = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"refresharrow.png"]];
  refreshArrow.frame = CGRectMake((scrollView.contentOffset.y + REFRESH_HEADER_HEIGHT - 27) / 2,
                                  (scrollView.contentOffset.y + REFRESH_HEADER_HEIGHT - 44) / 2,
                                  27, 44);
  
  refreshSpinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];

  [tableview addSubview:refreshHeaderView];
  
  
  }
