ios - (iOS) 内购失败？

Question

我正在尝试执行应用内购买，但失败了，我也不知道为什么。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，由于我知道产品已获取并记录到控制台，问题不在于此。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 View Controller 收听有关付款的通知，并实际进行付款。这是 InAppPurchaseManager 内部发生的事情:

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

现在购买的商品已发送到商店。经理等待回应，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。沙盒账户可以正常使用，因为它可以在游戏中心进行测试。产品被提取是因为它把它全部打印出来了。但是当我尝试购买时，它就失败了，而且没有告诉我原因。被注销的代码就是一堆数字。

希望有人能帮助我。 此致 /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中断，则重新开始任何购买 [[SKPaymentQueue defaultQueue] addTransactionObserver:self];

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

2. 从商店中获取产品

   -(void) request10GoldData
   

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

3. 打印出来以验证它是否已被提取

   - (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

   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，并且在上面的 NSLog 语句中，它准确地打印出了我在 iTunes connect 中创建的内容。

好吧，真是无赖。我发现这就像在测试这个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错误。

所以对于其他有问题的人，试试这个: 1. 像这样记录错误描述:

    - (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];
    }
}

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

这为我解决了。感谢您提供帮助。下次我一定会先记录错误。
