Question

您好我正在使用表视图来选择取消选择单元格并获得所需的结果。但当我检查任何单元格并向下滚动时，也检查其他单元格上的显示

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {


        errorText!.removeFromSuperview()

        tableView.deselectRowAtIndexPath(indexPath, animated: false)
         let cell: UITableViewCell = tableView.cellForRowAtIndexPath(indexPath)!
        let person = numberArray[indexPath.row]

        if cell.accessoryType == .None {
            cell.accessoryType = .Checkmark
            selectedPeople.addObject(person)
        }else if cell.accessoryType == .Checkmark {
            cell.accessoryType = .None
            selectedPeople.removeObject(person)
        }

        print("\(selectedPeople)")
}

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        let cell = tableView.dequeueReusableCellWithIdentifier("commentCellss", forIndexPath: indexPath)


        for object in cell.contentView.subviews
        {
            object.removeFromSuperview();
        }


        let text1:UILabel = UILabel.init(frame: CGRectMake(20, 10, 350, 30))
        text1.font = UIFont.systemFontOfSize(23)
        text1.text = nameArray[indexPath.row] as? String
        cell.contentView.addSubview(text1)

        let text2:UILabel = UILabel.init(frame: CGRectMake(20, text1.frame.origin.y+text1.frame.size.height , 350, 30 ))
        text2.font = UIFont.systemFontOfSize(15)
        text2.text = numberArray[indexPath.row] as? String
        text2.textColor = UIColor.lightGrayColor()
        cell.contentView.addSubview(text2)


        let text3:UILabel = UILabel.init(frame: CGRectMake(0, text2.frame.origin.y+text2.frame.size.height+6 , 350, 1 ))
        text3.font = UIFont.systemFontOfSize(15)
        text3.backgroundColor = UIColor.darkGrayColor()
        cell.contentView.addSubview(text3)



        return cell
   }

        text1.font = UIFont.systemFontOfSize(23)
        text1.text = nameArray[indexPath.row] as? String

        let text2:UILabel = UILabel.init(frame: CGRectMake(20, text1.frame.origin.y+text1.frame.size.height , 350, 30 ))

        text2.textColor = UIColor.lightGrayColor()
        cell.contentView.addSubview(text2)


        let text3:UILabel = UILabel.init(frame: CGRectMake(0, text2.frame.origin.y+text2.frame.size.height+6 , 350, 1 ))
        text3.font = UIFont.systemFontOfSize(15)
        text3.backgroundColor = UIColor.darkGrayColor()
        cell.contentView.addSubview(text3)

        if (selectedPeople.contains(numberArray[indexPath.row])){
            cell.accessoryType = .Checkmark
        }
        else{
            cell.accessoryType = .None
         }

        return cell
   }

表格视图在滚动单元格时创建多个accessoryType
