重用 UITableViewCell 时，我的数据不会保留 - SWIFT 3

Question

当我向下滚动桌面时，我遇到了一些困难，单元格中的数据正在消失。我如何保留它们在我的数据源中更具体的？

提到我的单元格内部有收集视图，其中的项目显示不好。

class PromoTowerCollectionViewCell: UICollectionViewCell {

@IBOutlet weak var multiplierNumberLabel: UILabel!
@IBOutlet weak var iconPromo: UIImageView!
@IBOutlet weak var namePromoLabel: UILabel!
@IBOutlet weak var priceCutLabel: UILabel!
@IBOutlet weak var priceActualLabel: UILabel!
@IBOutlet weak var infoPopUp: MyButton!
    // MARK: - Setters
var kid : PromoPackageKid? {
    didSet {
        self.namePromoLabel.text = kid?.name
        self.multiplierNumberLabel.text = kid?.power
        self.priceActualLabel.text = String(describing: kid!.prices[Constants.CARD_PAYMENT]!) + " €"
        self.infoPopUp.promoText = kid?.texts
        if kid?.prices[Constants.CARD_PAYMENT] != kid?.commonPrices[Constants.CARD_PAYMENT] {
            let stringPrice = String(describing:kid!.commonPrices[Constants.CARD_PAYMENT]!) + " €"
            let attributeString = NSMutableAttributedString(string: stringPrice)
            attributeString.addAttribute(NSStrikethroughStyleAttributeName, value: 1, range: NSMakeRange(0, attributeString.length))
            self.priceCutLabel.attributedText = attributeString
        } else {
            self.priceCutLabel.isHidden = true
        }
    }
}

那将是我的收藏viewitem，其中包含我填充它的数据。

class PromoTowerTableViewCell: UITableViewCell {
var package : PromoPackage? {
    didSet {
        collectionView.reloadData()
    }
}
        @IBOutlet weak var collectionView: PromoTowerCollectionView!
    // MARK: - Lifecycle
    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
        collectionView.dataSource = self
        collectionView.delegate = self
        collectionView.register(UINib(nibName: "PromoTowerCollectionCell", bundle: nil), forCellWithReuseIdentifier: "PromoTowerCollectionViewCell")
        collectionView.reloadData()
    }
    override func setSelected(_ selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)
    }
}
// MARK: DataSource
extension PromoTowerTableViewCell: UICollectionViewDataSource {
    func numberOfSections(in collectionView: UICollectionView) -> Int {
        return 1
    }
    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return package?.kids.count ?? 0
    }
    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "PromoTowerCollectionViewCell", for: indexPath) as! PromoTowerCollectionViewCell
        cell.kid = package?.kids[indexPath.row]
        cell.iconPromo.image = UIImage(named: iconImages[indexPath.row])
        return cell
    }
}
        //MARK: Delegate
    extension PromoTowerTableViewCell: UICollectionViewDelegate {
    func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
        if let cell = collectionView.cellForItem(at: indexPath) as? PromoTowerCollectionViewCell {
            cell.layer.borderWidth = 2.0
            cell.layer.borderColor = Theme.defaultColor().cgColor
            cell.layer.shadowOffset = CGSize.init(width: 0.5, height: 0.5)
        }
    }

至于我的维护=>

     // MARK: - UITableViewDataSource + Delegate
    func expandableCell(forSection section: Int, inTableView tableView: ExpyTableView) -> UITableViewCell {
        let currentPackage = self.packages[section]
        if section < self.packages.count {
        if currentPackage.type == "bundle"{
                let cell = tableView.dequeueReusableCell(withIdentifier: "PromoTowerCell") as! PromoTowerTableViewCell
                cell.package = currentPackage
                return cell
            }

Datasource and Delegate应在ViewController中持有collectionView，单元格仅应包含您的UIViews，您将在单元格中设置单元格内容，即tableView或collectionView将重新加载单元格和您将丢失数据，而应该在cellForRowAtIndexpath中设置值，而您遵循的方法确实很奇怪。

arrayOne = ["Item 1", "Item 2", "Item 3"]
arrayTwo = ["Item A", "Item B", "Item C"]
// MARK: Delegate & DataSource
func numberOfSections(in collectionView: UICollectionView) -> Int {
    return 1
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return arrayOne.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "PromoTowerCollectionViewCell", for: indexPath) as! PromoTowerCollectionViewCell
       cell.iconPromo.text = arrayOne[indexPath.row]
       cell.namePromoLabel.text = arrayTwo[indexPath.row]
    return cell
}
