在应用程序购买之后,应用程序在启动时崩溃.产品识别=无？

Question

我有一些用户报告说,在尝试购买应用程序后,该应用程序现在在启动时崩溃.我已要求他们删除并重新安装尚未运行的应用程序,并试图让他们进入飞行模式以停止任何无效的网络通信.

我无法在我的设备上复制错误,我的应用程序购买在沙箱和生产模式中完成得很好.我的想法是,他们的事务以某种方式收到了一个nil productIdentifier,导致启动崩溃,但我不确定在app启动时调用哪些事务观察器方法,我可以为他们解决问题.

有没有办法"清除"事务队列或在启动时测试nil productidentifier并允许这些用户至少再次运行应用程序？我已经使用下面的代码完成了几百个应用内购买,而这最近刚开始发生.在app启动时调用哪个辅助方法？

在AppDelegate.m中

[[SKPaymentQueue defaultQueue] addTransactionObserver:[MovieClockIAPHelper sharedHelper]];

在app帮助程序代码中:

- (id)initWithProductIdentifiers:(NSSet *)productIdentifiers {
    if ((self = [super init])) {

        // Store product identifiers
        _productIdentifiers = [productIdentifiers retain];

        // Check for previously purchased products

        NSMutableSet * purchasedProducts = [NSMutableSet set];
        for (NSString * productIdentifier in _productIdentifiers) {

            BOOL productPurchased = [[NSUserDefaults standardUserDefaults] boolForKey:productIdentifier];

            if (productPurchased) {
                [purchasedProducts addObject:productIdentifier];
                NSLog(@"Previously purchased: %@", productIdentifier);
            }
            else{
            NSLog(@"Not purchased: %@", productIdentifier);
            }
        }
        self.purchasedProducts = purchasedProducts;

    }
    return self;
}

- (void)requestProducts {

    self.request = [[[SKProductsRequest alloc] initWithProductIdentifiers:_productIdentifiers] autorelease];
    _request.delegate = self;
    [_request start];

}

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response {

    NSLog(@"Received products results...");   
    self.products = response.products;
    self.request = nil;    

    [[NSNotificationCenter defaultCenter] postNotificationName:kProductsLoadedNotification object:_products];    
}


- (void)restoreCompletedTransactions {
    [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}

- (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];

    [[SKPaymentQueue defaultQueue] finishTransaction: transaction];

}

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
    NSLog(@"in the payment queue");

    for (SKPaymentTransaction *transaction in transactions)
    {

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

}

-(void)buyProduct:(SKProduct *)product
{
    NSLog(@"In buyproduct Buying %@...", product.productIdentifier);

    SKPayment *payment = [SKPayment paymentWithProduct:product];

    [[SKPaymentQueue defaultQueue] addPayment:payment];
}

- (void)dealloc
{
    [_productIdentifiers release];
    _productIdentifiers = nil;
    [_products release];
    _products = nil;
    [_purchasedProducts release];
    _purchasedProducts = nil;
    [_request release];
    _request = nil;
    [super dealloc];
}

Answer 1

当事务处于SKPaymentTransactionStateRestored时,我遇到了类似的问题.我的测试表明这可能是IOS 7.0.3的问题,但我无法验证这一点.

StoreKit会保留应用程序必须完成的持久事务列表.正如您所知,交易将在每次启动时报告,直至完成.

我们实施的解决方案是在从入口点使用之前检查产品标识符是否为零:

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

即使我们收到了一个没有产品标识符的交易,我们也能够成功通话finishTransaction.

我希望这有帮助.

Answer 2

我的一位用户四天前抱怨同样的问题并且能够向我发送崩溃日志.他在iPhone 5,2上使用iOS 7.0.3.在尝试使用originalTransaction.payment的productIdentifier属性构建字典时,在识别SKPaymentTransactionStateRestored后发生崩溃:

NSDictionary* userInfoDict = @{@"productID":transaction.payment.productIdentifier};

我认为originalTransaction或其属性payment或productIdentifier都是nil.我从transaction.payment.productIdentifier中存储了productIdentifier,而不是从transaction.originalTransaction.payment.productIdentifier中存储,同时还原并将其用作productIdentifier:

case SKPaymentTransactionStateRestored:
{
  NSString *productID = transaction.originalTransaction.payment.productIdentifier;
  if (!productID) {
    productID = transaction.payment.productIdentifier;
  }
  [self handlePurchaseSuccessful:transaction.originalTransaction productIdentifier:productID];
}

如果能解决问题,仍在等待审核/反馈.
