Swift代码库之分页制作tableview加载数据按钮（含demo源码）

实现代码

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        if (indexPath.section == 1){
         
            
            let cell = tableView.dequeueReusableCell(withIdentifier: "loadmorecell", for: indexPath)
            //cell.textLabel?.text="请点击载入更多"
            
            return cell
          
        }
        let cell = tableView.dequeueReusableCell(withIdentifier: "VisitWordCell", for: indexPath) as! WordCell
        
        let oneWord = wordList[indexPath.row]
        cell.wName.text=checkSub(mStr: oneWord.wNameStr, sStr: "")
        cell.wImage.image = imageDB?.readData(tupian: oneWord.wImageStr)
        //cell.wPinYin.text = "拼音:"+oneWord.wPinYin
        //cell.wBushou.text = "部首:"+oneWord.wBushou
        //cell.wZBihua.text = "笔画:"+String(oneWord.wZBihua)
        cell.wXuhao.text  = "序号:"+String(oneWord.wXuhao)
        return cell
    }
