我正在应用程序购买(非耗用类型歌曲).when中实现一个用户点击购买每一首歌曲，我称之为startPurchase功能.my歌曲内容是通过我的服务器交付的。

在我购买了一些东西并再次尝试重新购买时，它不会被视为purchase.it的还原，使一个新的purchase.the委托方法被多次调用。

实际上，我的问题是，我点击购买和继续付款，并购买了该项目。

再次，当我试图购买同样的项目苹果警报说“你已经购买了这个项目，点击可以下载”当我点击" ok ".this不属于SKPaymentTransactionStatePurchased.why，而是它去了SKPaymentTransactionStatePurchased.why，这正在发生吗？请帮帮忙

请帮帮我

我认为您的问题是添加事务服务器副本，反映下面代码的尝试，以避免添加事务服务器副本，这可能是有效的：

- (void)startPurchase:(NSString*)inProductId{

  if ([SKPaymentQueue canMakePayments])
  {
     myProductId = inProductId

    SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:myProductId]];
    productsRequest.delegate = self;
    [productsRequest start];
  }
  else {
    NSLog(@"Parental-controls are enabled");
      }

}
static bool hasAddObserver=NO;
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:
  (SKProductsResponse *)response {

  NSLog(@"response received");
  SKProduct *validProduct = nil;
  int count = [response.products count];

  UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"Message" message:
  [NSString stringWithFormat:@"%d",response.products.count] delegate:
  self cancelButtonTitle:@"OK" otherButtonTitles:nil];

  [alert show];
  [alert release];

  if (count > 0) {
    validProduct = [response.products objectAtIndex:0];
    NSLog(@"products available");
    SKPayment *payment = [SKPayment paymentWithProductIdentifier:myProductId];
    if (!hasAddObserver) {
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    hasAddObserver=YES;
    }
    [[SKPaymentQueue defaultQueue] addPayment:payment];
  }
  else if (!validProduct) {
    NSLog(@"No products available");
  }
}

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
    for (SKPaymentTransaction *transaction in transactions)
    {
        SKPayment *payment = [transaction payment];

      if([payment.productIdentifier isEqualToString:myProductId])
      {
          NSLog(@"%@payement queue payment.productIdentifier",payment.productIdentifier);

        switch (transaction.transactionState)
        {
            case SKPaymentTransactionStatePurchased:
                NSLog(@"completeTransaction");
                [self completeTransaction:transaction];
                break;
            case SKPaymentTransactionStateFailed:
                NSLog(@"failedTransaction");
                [self failedTransaction:transaction];
                break;
            case SKPaymentTransactionStateRestored:
                NSLog(@"restoreTransaction");
                [self restoreTransaction:transaction];
            default:
                break;
        }
      }
    }
}

- (void)provideContent:(NSString *)productIdentifier
{
    NSLog(@"Provide Content %@", productIdentifier);

    }

- (void)recordTransaction:(SKPaymentTransaction *)transaction {
    NSLog(@"inside the recordTransaction");

}

- (void) completeTransaction: (SKPaymentTransaction *)transaction
{
    [self recordTransaction: transaction];
    [self provideContent: transaction.payment.productIdentifier];
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction];


}

- (void) restoreTransaction: (SKPaymentTransaction *)transaction
{
    NSLog(@"restoreTransaction transaction inside");

   }

- (void) failedTransaction: (SKPaymentTransaction *)transaction
{
    if (transaction.error.code != SKErrorPaymentCancelled)
    {
        if(transaction.error.code == SKErrorUnknown) {
            NSLog(@"Unknown Error (%d), product: %@", (int)transaction.error.code, transaction.payment.productIdentifier);
            UIAlertView *failureAlert = [[UIAlertView alloc] initWithTitle :@"In-App-Purchase Error:"
            message: @"There was an error purchasing this item please try again."
            delegate : self cancelButtonTitle:@"OK"otherButtonTitles:nil];
            [failureAlert show];
            [failureAlert release];
        }

        if(transaction.error.code == SKErrorClientInvalid) {
            NSLog(@"Client invalid (%d), product: %@", (int)transaction.error.code, transaction.payment.productIdentifier);
            UIAlertView *failureAlert = [[UIAlertView alloc] initWithTitle :@"In-App-Purchase Error:"
            message: @"There was an error purchasing this item please try again."
            delegate : self cancelButtonTitle:@"OK"otherButtonTitles:nil];
            [failureAlert show];
            [failureAlert release];
        }

        if(transaction.error.code == SKErrorPaymentInvalid) {
            NSLog(@"Payment invalid (%d), product: %@", (int)transaction.error.code, transaction.payment.productIdentifier);
            UIAlertView *failureAlert = [[UIAlertView alloc] initWithTitle :@"In-App-Purchase Error:"
            message: @"There was an error purchasing this item please try again."
            delegate : self cancelButtonTitle:@"OK"otherButtonTitles:nil];
            [failureAlert show];
            [failureAlert release];
        }

        if(transaction.error.code == SKErrorPaymentNotAllowed) {
            NSLog(@"Payment not allowed (%d), product: %@", (int)transaction.error.code, transaction.payment.productIdentifier);
            UIAlertView *failureAlert = [[UIAlertView alloc] initWithTitle :@"In-App-Purchase Error:"
            message: @"There was an error purchasing this item please try again."
            delegate : self cancelButtonTitle:@"OK"otherButtonTitles:nil];
            [failureAlert show];
            [failureAlert release];
        }
    }
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction];
}

在您的I am检查中，是否在代码下面添加了事务服务器：

if (!hasAddObserver) {
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    hasAddObserver=YES;
    }

hasAddObserver变量静态bool数据类型是检查是否已经添加，易于添加检查事务服务器！

就苹果官方文件上的说法而言，这是正常行为：

“如果用户试图购买可恢复的产品(而不是使用您实现的恢复接口)，则应用程序将接收该项的常规事务，而不是恢复事务。但是，该产品不会再次向用户收取费用。您的应用程序应该以与原始事务相同的方式对待这些事务。”
