(iOS) 应用内购买失败？

Question

我正在尝试执行应用内购买，但失败了，我不知道为什么。奇怪的是，它可以很好地获取 SKProduct 并且可以打印所有详细信息，但是当我真正尝试购买它时，它就失败了。

现在，因为我知道产品被提取并记录到控制台，所以问题不在于那个。问题出在我尝试实际购买获取的产品时，所以这里是代码：

- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.

// Setup notifaction to handle the successfull payment
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(succeedPayment)
                                             name:@"kInAppPurchaseManagerTransactionSucceededNotification"
                                           object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(failedPayment)
                                             name:@"kInAppPurchaseManagerTransactionFailedNotification"
                                           object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(cancelPayment)
                                             name:@"userCancel"
                                           object:nil];
}

- (IBAction)purchase10Crystals:(id)sender {
    InAppPurchaseManager *p = [InAppPurchaseManager IAPManager];
    if ([p canMakePurchases]) {
        [p purchaseGoldCoins:10];
        NSLog(@"Buying 10 crystals");
    }
}

所以我让视图控制器收听有关付款的通知，并实际进行付款。以下是 InAppPurchaseManager 内部发生的情况：

SKPayment *payment = [SKPayment paymentWithProduct:gold10];
    [[SKPaymentQueue defaultQueue] addPayment:payment];

现在购买已发送到商店。经理等待响应，这些是选项：

    //
// removes the transaction from the queue and posts a notification with the transaction result
//
- (void)finishTransaction:(SKPaymentTransaction *)transaction wasSuccessful:(BOOL)wasSuccessful
{
    // remove the transaction from the payment queue.
    [[SKPaymentQueue defaultQueue] finishTransaction:transaction];

    NSDictionary *userInfo = [NSDictionary dictionaryWithObjectsAndKeys:transaction, @"transaction" , nil];
    if (wasSuccessful)
    {
        // send out a notification that we’ve finished the transaction
        [[NSNotificationCenter defaultCenter] postNotificationName:kInAppPurchaseManagerTransactionSucceededNotification object:self userInfo:userInfo];
        NSLog(@"Success transaction!");
    }
    else
    {
        // send out a notification for the failed transaction
        [[NSNotificationCenter defaultCenter] postNotificationName:kInAppPurchaseManagerTransactionFailedNotification object:self userInfo:userInfo];
    }
}

//
// called when the transaction was successful
//
- (void)completeTransaction:(SKPaymentTransaction *)transaction
{
    [self recordTransaction:transaction];
    [self provideContent:transaction.payment.productIdentifier];
    [self finishTransaction:transaction wasSuccessful:YES];

}

//
// called when a transaction has been restored and and successfully completed
//
- (void)restoreTransaction:(SKPaymentTransaction *)transaction
{
    [self recordTransaction:transaction.originalTransaction];
    [self provideContent:transaction.originalTransaction.payment.productIdentifier];
    [self finishTransaction:transaction wasSuccessful:YES];
}

//
// called when a transaction has failed
//
- (void)failedTransaction:(SKPaymentTransaction *)transaction
{
    if (transaction.error.code != SKErrorPaymentCancelled)
    {
        // error!
        NSLog(@"Failed: %li", (long)transaction.error);
        [self finishTransaction:transaction wasSuccessful:NO];
    }
    else
    {
        // this is fine, the user just cancelled, so don’t notify
        [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
        [[NSNotificationCenter defaultCenter] postNotificationName:@"userCancel" object:self userInfo:nil];
    }
}

被调用的方法是failedTransaction。我不知道为什么。沙盒帐户正在运行，因为它可以在游戏中心进行测试。该产品被提取是因为它全部打印出来。但是当我尝试购买时，它只是失败了，并且没有告诉我为什么。被注销的代码只是很多数字。

希望任何人都可以帮助我。 最好的祝福 /JBJ

编辑 这就是我获取 SKProducts 的方式。

1. 首先我调用它来加载它

   - (void)loadStore
   

   { // 如果上次应用程序打开时被中断，则重新开始购买 [[SKPaymentQueue defaultQueue] addTransactionObserver:self];

   // get the product description (defined in early sections)
   [self request10GoldData];
   

   }

2. 从商店获取产品

   -(void) request10GoldData
   

   { NSSet *productIdentifiers = [NSSet setWithObject:@"10crystals" ]; productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdentifiers]; productsRequest.delegate = self; [产品请求开始]; }

3. 打印出来验证它是否被提取

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

   { // 创建一个新的 SKProduct，识别它是哪个产品，并添加到适当的实例变量中

   NSArray *products = response.products;
   SKProduct *theProduct = [products count] == 1 ? [products objectAtIndex:0] : nil;
   if (theProduct)
   {
       // Identify the product and assign to instance variable SKProducts
       if ([theProduct.productIdentifier isEqualToString:@"10crystals"]) {
           gold10 = theProduct;
       }
   
       // Debugging
       NSLog(@"Product title: %@" , theProduct.localizedTitle);
       NSLog(@"Product description: %@" , theProduct.localizedDescription);
       NSLog(@"Product price: %@" , theProduct.price);
       NSLog(@"Product id: %@" , theProduct.productIdentifier);
   }
   
   for (NSString *invalidProductId in response.invalidProductIdentifiers)
   {
       NSLog(@"Invalid product id: %@" , invalidProductId);
   }
   
   
   [[NSNotificationCenter defaultCenter] postNotificationName:kInAppPurchaseManagerProductsFetchedNotification object:self userInfo:nil];
   

   }

这行得通，在上面的 NSLog 语句中，它准确地打印出我在 iTunes 连接中创建的内容。

好吧，真可惜。我发现它就像在测试时注销我的实际帐户一样简单-.-'我没有发现其他人有这个问题，因为我没有打印出交易的错误。

所以对于其他有问题的人，试试这个： 1. 记录错误描述如下：

    - (void)failedTransaction:(SKPaymentTransaction *)transaction
{
    // Log the error
    NSLog(@"%@", [transaction.error localizedDescription]);

    if (transaction.error.code != SKErrorPaymentCancelled)
    {
        // error!
        [self finishTransaction:transaction wasSuccessful:NO];
    }
    else
    {
        // this is fine, the user just cancelled, so don’t notify
        [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
        [[NSNotificationCenter defaultCenter] postNotificationName:@"userCancel" object:self userInfo:nil];
    }
}

如果错误提示“无法连接到 iTunes 商店”-> 请转到您的测试设备上的设置，然后退出您的实际帐户，以便您可以登录您的测试帐户！

这为我解决了这个问题。感谢您尝试提供帮助。下次我一定会先把错误记录下来。
