试试这个逻辑希望这会解决你的问题

    let dict = [NSIndexPath: String]()

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
         let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath)

         if let _ = // dict contains value at indexpath {
             cell.accessoryType = .Checkmark
         } else {
             cell.accessoryType = .None
         }

         return cell
     }


    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
          if ( // dict contains value == indexpath) {
              // remove value from dict
          } else {
          //add value to dict
          }
          tableView.reloadRowsAtIndexPaths([indexPath], withRowAnimation: .Automatic)
      }
