UITableView在上一节中复制了单元格

Question

我有一个包含3个部分的表视图。 在最后一节我有两个单元格。 不，当我点击最后一个单元格（Segue到ViewController）并返回到tableView时，我的最后一个单元格与前一个单元格完全相同（第2行第0行）。当我关闭应用程序并返回到表时，一切正常。 我搜索过很多但却一无所获。

这是我的代码：

else if indexPath.section == 2 {

        let cell2:SecondTwoWayCellTableViewCell = self.tableView.dequeueReusableCellWithIdentifier("SecondTwoWayCell") as!SecondTwoWayCellTableViewCell



                if indexPath.row == 0 && DoubleMatchIdentifierHome[4] != "" {



                    let currentPlayerHome1 = CoreDataManager.defaultListener().getPlayer(date, identifier: DoubleMatchIdentifierHome[4]) as! Player
                    let currentPlayerHome2 = CoreDataManager.defaultListener().getPlayer(date, identifier: DoubleMatchIdentifierHome[5]) as! Player

                    let currentPlayerAway1 = CoreDataManager.defaultListener().getPlayer(date, identifier: DoubleMatchIdentifierAway[4]) as! Player
                    let currentPlayerAway2 = CoreDataManager.defaultListener().getPlayer(date, identifier: DoubleMatchIdentifierAway[5]) as! Player


                    cell2.identifierPlayerHome1.text     = DoubleMatchIdentifierHome[4]
                    cell2.playerHome1.text               = currentPlayerHome1.name!
                    cell2.identifierPlayerHome2.text     = DoubleMatchIdentifierHome[5]
                    cell2.playerHome2.text               = currentPlayerHome2.name!

                    cell2.identifierPlayerAway1.text     = DoubleMatchIdentifierAway[4]
                    cell2.playerAway1.text               = currentPlayerAway1.name!
                    cell2.identifierPlayerAway2.text     = DoubleMatchIdentifierAway[5]
                    cell2.playerAway2.text               = currentPlayerAway2.name!

                    cell2.score.text         = ("\(matches[18].scoreHome!):\(matches[18].scoreAway!)")

                     return cell2
            }

            else if indexPath.row == 1 && DoubleMatchIdentifierHome[6] != "" {




                    let currentPlayerHome1 = CoreDataManager.defaultListener().getPlayer(date, identifier: DoubleMatchIdentifierHome[6]) as! Player
                    let currentPlayerHome2 = CoreDataManager.defaultListener().getPlayer(date, identifier: DoubleMatchIdentifierHome[7]) as! Player

                    let currentPlayerAway1 = CoreDataManager.defaultListener().getPlayer(date, identifier: DoubleMatchIdentifierAway[6]) as! Player
                    let currentPlayerAway2 = CoreDataManager.defaultListener().getPlayer(date, identifier: DoubleMatchIdentifierAway[7]) as! Player




                    cell2.identifierPlayerHome1.text     = DoubleMatchIdentifierHome[6]
                    cell2.playerHome1.text               = currentPlayerHome1.name!
                    cell2.identifierPlayerHome2.text     = DoubleMatchIdentifierHome[7]
                    cell2.playerHome2.text               = currentPlayerHome2.name!

                    cell2.identifierPlayerAway1.text     = DoubleMatchIdentifierAway[6]
                    cell2.playerAway1.text               = currentPlayerAway1.name!
                    cell2.identifierPlayerAway2.text     = DoubleMatchIdentifierAway[7]
                    cell2.playerAway2.text               = currentPlayerAway2.name!

                    cell2.score.text         = ("\(matches[19].scoreHome!):\(matches[19].scoreAway!)")

                     return cell2

            }

       return cell2






    }

Answer 1

问题可能是你在代码开头打开单元格：

让cell2：SecondTwoWayCellTableViewCell = self.tableView.dequeueReusableCellWithIdentifier（＆＃34; SecondTwoWayCell＆＃34;）as！SecondTwoWayCellTableViewCell

你做了if if check to things ...但你不清理单元格并记住你正在重用一个带有标识符的单元格... 所以，你需要做的只是在你通过放置像：

之类的东西来清除单元格之后清除单元格

cell2 = SecondTwoWayCellTableViewCell（）

然后＆＃34;如果indexPath.row == 0＆amp;＆amp; DoubleMatchIdentifierHome [4]！=＆＃34;＆＃34; {＆＃34;

因此，如果单元格不属于任何if，则单元格始终为标准值。
