Question

抱歉，我知道这是一个重复的问题，但我无法理解其他问题的答案。

我的自定义单元格在滚动时正在改变。我知道这是由于重用标识符，但我不知道如何解决它。任何帮助，将不胜感激。我也使用indexPath.row来访问数组。

即使我使用重用标识符，如何让我的表格视图不会更改滚动值？

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell : TeamCell = tableView.dequeueReusableCell(withIdentifier: "TeamCell", for: indexPath) as! TeamCell

    cell.trainer.image = UIImage(named: "t\(Player.User.Gold.trainers[(indexPath as NSIndexPath).row].imageID)")
    if Player.User.Gold.trainers[(indexPath as NSIndexPath).row].p1.name != 0 {
        cell.pokemon1.image = UIImage(named: "\(Player.User.Gold.trainers[(indexPath as NSIndexPath).row].p1.name)")
        cell.pokemon1.isHidden = false
    } else {
        cell.pokemon1.isHidden = true
    }
    if Player.User.Gold.trainers[(indexPath as NSIndexPath).row].p2.name != 0 {
        cell.pokemon2.image = UIImage(named: "\(Player.User.Gold.trainers[(indexPath as NSIndexPath).row].p2.name)")
        cell.pokemon1.isHidden = false
    } else {
        cell.pokemon2.isHidden = true
    }
    if Player.User.Gold.trainers[(indexPath as NSIndexPath).row].p3.name != 0 {
        cell.pokemon3.image = UIImage(named: "\(Player.User.Gold.trainers[(indexPath as NSIndexPath).row].p3.name)")
        cell.pokemon1.isHidden = false
    } else {
        cell.pokemon3.isHidden = true
    }
    if Player.User.Gold.trainers[(indexPath as NSIndexPath).row].p4.name != 0 {
        cell.pokemon4.image = UIImage(named: "\(Player.User.Gold.trainers[(indexPath as NSIndexPath).row].p4.name)")
        cell.pokemon1.isHidden = false
    } else {
        cell.pokemon4.isHidden = true
    }
    if Player.User.Gold.trainers[(indexPath as NSIndexPath).row].p5.name != 0 {
        cell.pokemon5.image = UIImage(named: "\(Player.User.Gold.trainers[(indexPath as NSIndexPath).row].p5.name)")
        cell.pokemon1.isHidden = false
    } else {
        cell.pokemon5.isHidden = true
    }
    if Player.User.Gold.trainers[(indexPath as NSIndexPath).row].p6.name != 0 {
        cell.pokemon6.image = UIImage(named: "\(Player.User.Gold.trainers[(indexPath as NSIndexPath).row].p6.name)")
        cell.pokemon1.isHidden = false
    } else {
        cell.pokemon6.isHidden = true
    }

    return cell
}

（该函数只检查数组的值是否为0，如果它不是，则显示图像）

Answer 1

将您的每个宠物小精灵images设置为nil或在placeholder image单元后立即设置dequeue，然后将您的每个if-conditions设置为每个图片视图默认隐藏属性也是如此，如果您的imageview默认隐藏，则在true条件下设置图像之前将其隐藏属性设置为if！

Answer 2

所以评论说这个问题是错误地将pokemon1设置在每个if中。

修改

因为我将更加精确地预测：在每个if条件下，你将pokemon1设置为vissible。你需要使用你的设置作为图像的Pokomen。

有趣的编码
