Question

我在故事板中启用了一个启用了分页的collectionView。每个集合视图单元格是屏幕的整个宽度

return CGSize(width: collectionView.bounds.width, height: collectionView.bounds.height)

我正在尝试设置IAP并遇到问题。每个单元格都有一个按钮，用于在点击时检查与该行关联的product_ID。

    print("About to fetch the product...")

    // Can make payments
    if (SKPaymentQueue.canMakePayments())
    {
        let productID:NSSet! = NSSet(object: self.product_ID)
        let productsRequest:SKProductsRequest = SKProductsRequest(productIdentifiers: productID as! Set<String>)
        productsRequest.delegate = self
        productsRequest.start()
        print("Fetching Products")
    }else{
        print("Can't make purchases")
        UIAlertView(title: "Purchases Disabled",
                    message: "Purchases are disabled on your device! Enable Purchases in the Restriction Settings on your device.",
                    delegate: nil, cancelButtonTitle: "OK").show()
    }

付款队列

 func paymentQueue(_ queue: SKPaymentQueue,
                  updatedTransactions transactions: [SKPaymentTransaction])

{
    print("Received Payment Transaction Response from Apple")

    for transaction:AnyObject in transactions {
        if let trans:SKPaymentTransaction = transaction as? SKPaymentTransaction{
            switch trans.transactionState {
            case .purchased:
                print("Product Purchased")
                SKPaymentQueue.default().finishTransaction(transaction as! SKPaymentTransaction)
                // Handle the purchase
                print(product_ID)
                UserDefaults.standard.set(true, forKey: product_ID)
                setTitle = "Apply Theme"
            case .failed:
                print("Purchased Failed")
                setTitle = "4.99"
                SKPaymentQueue.default().finishTransaction(transaction as! SKPaymentTransaction)
            case .restored:
                print("Already Purchased")
                //SKPaymentQueue.default().restoreCompletedTransactions()
                // Handle the purchase
                UserDefaults.standard.set(true, forKey: product_ID)
                setTitle = "Apply Theme"
            default:
                break
            }
            purchaseButton.setTitle(setTitle, for: .normal)
        }
    }

}

`

我遇到的问题是，当我按下按钮时，它不返回1个产品ID，它返回3.它处理我选择 和每个相邻单元格的单元格的付款。 即可。似乎即使其他单元格在屏幕外，它们仍然是活动的。它们似乎没有被系统删除。这个问题有方法解决吗？我以前从未遇到过像这样的问题。

隐藏的相邻CollectionViewCells仍然有效吗？
