iphone - 在 App Purchase SKPaymentQueue finishTransaction 中不起作用

Question

我正在 iOS sdk 中的应用程序购买项目中工作。我已经准备了应用程序购买类，用于从应用程序商店购买应用程序，并启用项目的内部内容。但是，我的问题是 SKPaymentQueue 没有完成我的类。这里的代码我的应用内购买类(class):

- (void)purchase {
    [[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
    SKPayment *payment = [SKPayment paymentWithProductIdentifier:@"com.test"];
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    [[SKPaymentQueue defaultQueue] addPayment:payment];

}

- (void)provideContent:(NSString *)productIdentifier {

    NSLog(@"Toggling flag for: %@", productIdentifier);
    [[NSUserDefaults standardUserDefaults] setBool:TRUE forKey:productIdentifier];
    [[NSUserDefaults standardUserDefaults] synchronize];
    //[_purchasedProducts addObject:productIdentifier];

    [[NSNotificationCenter defaultCenter] postNotificationName:kProductPurchasedNotification object:productIdentifier];

}

- (void)completeTransaction:(SKPaymentTransaction *)transaction {

    NSLog(@"completeTransaction...");

    //[self recordTransaction: transaction];
    [self provideContent: transaction.payment.productIdentifier];
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction];

}

- (void)restoreTransaction:(SKPaymentTransaction *)transaction {

    NSLog(@"restoreTransaction...");

    //[self recordTransaction: transaction];
    [self provideContent: transaction.originalTransaction.payment.productIdentifier];
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction];

}

- (void)failedTransaction:(SKPaymentTransaction *)transaction {

    if (transaction.error.code != SKErrorPaymentCancelled)
    {
        NSLog(@"Transaction error: %@", transaction.error.localizedDescription);
    }


    [[NSNotificationCenter defaultCenter] removeObserver:self name:kProductPurchaseFailedNotification object:transaction];


    [[NSNotificationCenter defaultCenter] postNotificationName:kProductPurchaseFailedNotification object:transaction];


    //[[NSNotificationCenter defaultCenter] postNotificationName:@"NotificationName" object:transaction];

    [[SKPaymentQueue defaultQueue] finishTransaction:transaction];

}



- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {

    for (SKPaymentTransaction *transaction in transactions) {

        switch (transaction.transactionState) {

            case SKPaymentTransactionStatePurchasing:

                break;

            case SKPaymentTransactionStatePurchased:
                [self completeTransaction:transaction];
                //[[SKPaymentQueue defaultQueue] finishTransaction:transaction];

                break;

            case SKPaymentTransactionStateRestored:
                //[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                [self restoreTransaction:transaction];

                break;

            case SKPaymentTransactionStateFailed:
                if (transaction.error.code != SKErrorPaymentCancelled) {
                    NSLog(@"An error encounterd");
                }
                else {
                    NSLog(@"Cancelled!");
                }
                //[[SKPaymentQueue defaultQueue] finishTransaction:transaction];

                [self failedTransaction:transaction];

                break;

        }

    }

}

- (void)dealloc
{
    [[SKPaymentQueue defaultQueue] removeTransactionObserver:self];

    [request release];
    [super dealloc];

}

那条线在我的类(class)上不起作用 [[SKPaymentQueue defaultQueue] finishTransaction:transaction]; 交易没有完成。我的另一个问题是 nsnotificationcenter 调用多次，就像我第一次点击它只调用一次没问题，另一次是 nsnotificationcenter 调用 3 次。

我得到了解决方案，你的问题是 addTransaction server duplicate to your issue，

尝试下面的代码它必须工作:

static bool hasAddObserver=NO;

- (void)purchase {
    if (!hasAddObserver) {//flag to fix this bug
        /*=====================================*/
        [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
        hasAddObserver=YES;
    }
    SKPayment *payment = [SKPayment paymentWithProductIdentifier:@"com.test"];
    //[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    [[SKPaymentQueue defaultQueue] addPayment:payment];

}


- (void)provideContent:(NSString *)productIdentifier {

    NSLog(@"Toggling flag for: %@", productIdentifier);
    [[NSUserDefaults standardUserDefaults] setBool:TRUE forKey:productIdentifier];
    [[NSUserDefaults standardUserDefaults] synchronize];
    //[_purchasedProducts addObject:productIdentifier];

    [[NSNotificationCenter defaultCenter] postNotificationName:kProductPurchasedNotification object:productIdentifier];

}

- (void)completeTransaction:(SKPaymentTransaction *)transaction {

    NSLog(@"completeTransaction...");

    //[self recordTransaction: transaction];
    [self provideContent: transaction.payment.productIdentifier];
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction];

}

- (void)restoreTransaction:(SKPaymentTransaction *)transaction {

    NSLog(@"restoreTransaction...");

    //[self recordTransaction: transaction];
    [self provideContent: transaction.originalTransaction.payment.productIdentifier];
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction];

}

- (void)failedTransaction:(SKPaymentTransaction *)transaction {

    if (transaction.error.code != SKErrorPaymentCancelled)
    {
        NSLog(@"Transaction error: %@", transaction.error.localizedDescription);
    }




    [[NSNotificationCenter defaultCenter] postNotificationName:kProductPurchaseFailedNotification object:transaction];


    //[[NSNotificationCenter defaultCenter] postNotificationName:@"NotificationName" object:transaction];

    [[SKPaymentQueue defaultQueue] finishTransaction:transaction];

}



- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {

    for (SKPaymentTransaction *transaction in transactions) {

        switch (transaction.transactionState) {

            case SKPaymentTransactionStatePurchasing:

                break;

            case SKPaymentTransactionStatePurchased:
                //[self completeTransaction:transaction];
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];

                break;

            case SKPaymentTransactionStateRestored:
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                //[self restoreTransaction:transaction];

                break;

            case SKPaymentTransactionStateFailed:
                if (transaction.error.code != SKErrorPaymentCancelled) {
                    NSLog(@"An error encounterd");
                }
                else {
                    NSLog(@"Cancelled!");
                }
                //[[SKPaymentQueue defaultQueue] finishTransaction:transaction];

                [self failedTransaction:transaction];

                break;

        }

    }

}

- (void)dealloc
{
    [[SKPaymentQueue defaultQueue] removeTransactionObserver:self];

    [request release];
    [super dealloc];

}

欢迎!
