UITableView重新加载数据问题

Question

当我重新加载UITableView时，它的某些单元格无法显示，但当我触摸屏幕时，它们会自动显示。这是UITableViewCellForRow代码。我正在使用代码[tblBuddyMesssageList reloadData];

重新加载表

 if (tableView.tag == UITableViewTagBuddyMessageList)
 {
    Message  *buddyMsg = self.arrBuddyMessages[indexPath.row];

    if ([buddyMsg.senderName isEqualToString:applicationDelegate.userInfo.userName] && [buddyMsg.receiverName isEqualToString:self.selectedBuddy.userName])
    {
        MessageSendByMeCell *cell = [tblBuddyMessageList dequeueReusableCellWithIdentifier:messageSendByMeCellIdentifier forIndexPath:indexPath];
        [self configureMessageSendByMeCell:cell forRowAtIndexPath:indexPath];
        return cell;
    }
     else
    {
        MessageSendByBuddyCell *cell = [tblBuddyMessageList dequeueReusableCellWithIdentifier:messageSendByBuddyCellIdentifier forIndexPath:indexPath];

        [self configureMessageSendByBuddyCell:cell forRowAtIndexPath:indexPath];
        return cell;        }
}
