ios - 删除 'Old' 恢复购买交易

Question

我一直在尝试在一个项目中测试恢复购买功能，但我遇到了这个错误的持续反馈:

Ignoring restoreCompletedTransactionsWithApplicationUsername: because already restoring transactions

我删除了一个沙盒测试员帐户，我认为有一个恢复购买的帐户仍处于付款循环中。我知道我永远不应该删除沙盒测试帐户，但现在已经有点晚了。

我能做些什么来清除在这个永无止境的循环中捕获的恢复事务吗？

编辑:

我修改后的代码:

序言:

class InAppPurchaseViewController: UIViewController, SKProductsRequestDelegate, SKPaymentTransactionObserver {

let defaults = NSUserDefaults.standardUserDefaults()
var product_id: NSString?;

@IBOutlet weak var unlockAction: UIButton!

override func viewDidLoad() {   
    super.viewDidLoad()

    SKPaymentQueue.defaultQueue().addTransactionObserver(self)   
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}
... }

1. 购买:

   @IBAction func unlockAction(sender: AnyObject) {

   product_id = "xxxx.iap.removeads";
   
   
   //Check if product is purchased
   if (defaults.boolForKey("purchased")){
       print("User already purchased this")
       // Hide a view or show content depends on your requirement
   }
   
   else if (!defaults.boolForKey("Purchased")){
       print("User has not yet purchased this")
   }
   
   
   print("About to fetch the products");
   
   // We check that user 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("User can make purchases and will fetch products from Apple Store now");
   }else{
       print("User can't make purchases");
   }
   

   // Proceed to buy the product.
   func buyProduct(product: SKProduct){
   print("Sending the Payment Request to Apple");
   let payment = SKPayment(product: product)
   SKPaymentQueue.defaultQueue().addPayment(payment);
   
   }
   
   func productsRequest (request: SKProductsRequest, didReceiveResponse response: SKProductsResponse) {
   
   let count : Int = response.products.count
   if (count>0) {
   
       let validProduct: SKProduct = response.products[0] as SKProduct
       if (validProduct.productIdentifier == self.product_id) {
           print(validProduct.localizedTitle)
           print(validProduct.localizedDescription)
           print(validProduct.price)
           buyProduct(validProduct);
       } else {
           print(validProduct.productIdentifier)
       }
   } else {
       print("nothing")
   }
   

   func request(request: SKRequest, didFailWithError error: NSError) {
   print("Error Fetching product information");
   }
   
   
   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")
   
               let alert = UIAlertController(title: "Thank You.", message: "Thank you for your purchase!", preferredStyle: UIAlertControllerStyle.Alert)
               alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler: nil))
               self.presentViewController(alert, animated: true, completion: nil)
               SKPaymentQueue.defaultQueue().finishTransaction(transaction as! SKPaymentTransaction)
               defaults.setBool(true , forKey: "purchased")
               break;
   
           case .Failed:
               print("Purchased Failed");
               SKPaymentQueue.defaultQueue().finishTransaction(transaction as! SKPaymentTransaction)
               break;
   
           case .Restored:
               print("Already Purchased");
               SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
               break;
   
           default:
               break;
           }
       }
   }
   

2. 恢复:

   @IBAction func restorePurchases(sender: AnyObject) {
   product_id = "xxxx.iap.removeads";
   SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
   
   func paymentQueue(queue: SKPaymentQueue!, updatedTransactions transactions: [AnyObject]!) {
   
       for transaction:AnyObject in transactions {
           if let trans:SKPaymentTransaction = transaction as? SKPaymentTransaction{
               switch trans.transactionState {
               case .Restored:
                   SKPaymentQueue.defaultQueue().finishTransaction(transaction as! SKPaymentTransaction)
                   let alert = UIAlertView(title: "Thank You", message: "Your purchase(s) were restored.", delegate: nil, cancelButtonTitle: "OK")
                   alert.show()
                   break;
   
               case .Failed:
                   SKPaymentQueue.defaultQueue().finishTransaction(transaction as! SKPaymentTransaction)
                   let alert = UIAlertView(title: "Sorry", message: "Your purchase(s) could not be restored.", delegate: nil, cancelButtonTitle: "OK")
                   alert.show()
                   break;
   
               default:
                   break;
               }
           }
       }
   }

只需创建一个新的测试用户，进行购买，然后测试恢复。 Apple 确实很难让测试用户进行应用内购买。根据我的经验，我总是创建新的测试用户，因为你不能删除他们的任何旧购买。因此，如果您想对初始购买进行两次测试，则需要两个测试用户。

但是至于你的问题，你应该只用这种方法检查一次交易:

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions{
for(SKPaymentTransaction *transaction in transactions){
    switch(transaction.transactionState){
        case SKPaymentTransactionStateRestored:
            NSLog(@"Transaction state -> Restored");
            //add the same code as you did from SKPaymentTransactionStatePurchased here
            [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
            break;

并确保你也有这个:

- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
    NSLog(@"received restored transactions: %lu", (unsigned long)queue.transactions.count);
    for(SKPaymentTransaction *transaction in queue.transactions){
    if(transaction.transactionState == SKPaymentTransactionStateRestored){
        //called when the user successfully restores a purchase
        NSLog(@"Transaction state -> Restored");

        //if you have more than one in-app purchase product,
        //you restore the correct product for the identifier.
        //For example, you could use
        //if(productID == kRemoveAdsProductIdentifier)
        //to get the product identifier for the
        //restored purchases, you can use
        //
        //NSString *productID = transaction.payment.productIdentifier;
        [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
        break;
    }
}
}

你应该像这样调用恢复购买:

- (IBAction) restore {
//this is called when the user restores purchases, you should hook this up to a button
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

}

希望对您有所帮助!
