问题描述

我在iOS sdk.i工作inapp购买项目准备了从appstore购买应用程序的inapp购买类，启用项目的内部内容。但是，我的问题是SKPaymentQueue没有完成我的class.here的代码我的inapp购买类：

i am working inapp purchase project in iOS sdk.i have prepared inapp purchase class for purchasing app from appstore with enable inner contents of the project.but, my problem is SKPaymentQueue doesn't finish working on my class.here's code of my inapp purchase 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];

}

该行不适用于我的班级 [[SKPaymentQueue defaultQueue] finishTransaction：transaction]; 交易未完成。
和我的另一个问题是nsnotificationcenter调用多次，如果我第一次点击它只调用一次没问题，另一次是nsnotificationcenter调用3次。

that's line doesn't work on my class [[SKPaymentQueue defaultQueue] finishTransaction:transaction]; transaction doesn't finish. and my another problem is nsnotificationcenter calls multiple times like if i click first time it's call only one time no problem,another time it's nsnotificationcenter calls 3 times.

推荐答案

我得到了解决方案你的问题是addTransaction服务器重复你的问题，

i got solution your problem is addTransaction server duplicate to your issue,

尝试下面的代码它必须工作：

try below code it's must working:

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];

}
