纯swift实现ipad版简单美团界面功能

—-> 2.3 数据源方法三 : 点击cell做出的相应数据改变

//MARK: - 点击左边的cell
extension XFJLRTableView : UITableViewDelegate {
 func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
  //判断是否是左边
  if tableView == leftTableView {//左边
   //获取子数据
   subData = delegateSource?.lrTableView(subDataSource: indexPath.row)
   //调用协议方法(传入用户点击的哪行)
   delegate?.lrTableView(seletLeftButton: indexPath.row)
   //记录用户点击了左侧的哪行
   seletIndex = indexPath.row
   //刷新表格
   rightTableView.reloadData()
  }else{ //右边
   //调用协议方法,传入右侧点击了哪行和左侧选中了哪行
   delegate?.lrTableView(seletRightButton: indexPath.row, seletLeftButton: seletIndex!)
  }
 }
