正在删除 '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，但我不断遇到此错误：

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然陷入付款循环。我知道我永远不应该删除沙盒测试帐户，但现在有点晚了。

我能做些什么来清除在这个永无止境的循环中捕获的还原事务吗？

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()
}
... }

购买：

@IBAction func unlockAction（发件人：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;
        }
    }
}

}

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，如果您想对首次购买进行两次测试，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！
