Hidden Adjacent CollectionViewCells are still active? - ios

Question

I have a collectionView with paging enabled in the storyboard. Each collection view cell is the full width of the screen
return CGSize(width: collectionView.bounds.width, height: collectionView.bounds.height)
I am trying to set up IAP and have encountered an Issue. Each cell has a button that checks for a product_ID associated with the row when tapped.
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()
}
payment queue
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)
}
}
}
`
The issue I have is that when I press the button, it doesn't return 1 productID, it returns 3. It processes the payment for the cell I select and every adjacent cell.. It seems that even when the other cells are off screen they are still active. They don't seem to be removed by the system. Is there a solution to this? I've never run into an issue like this before.
