swift - UITableView 上一节中重复的单元格

Question

我有一个包含 3 个部分的表格 View 。在最后一部分中，我有两个单元格。不，当我单击最后一个单元格(转到 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 部分第 0 行)。当我关闭应用程序并返回 tableView 时，一切正常。我搜索了很多，但没有发现任何相关内容。

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

问题可能是您在代码开头打开单元格，方法是:

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

您执行 if 来检查事物...但您没有清理单元格并记住您正在重复使用带有标识符的单元格...因此，您需要做的只是在将单元格出队后清除单元格，方法如下:

cell2 = SecondTwoWayCellTableViewCell()

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

因此，单元格始终会达到标准值，以防它不符合任何 if 条件。
