错误Domain=SKErrorDomain Code=3“无法连接到iTunes存储”UserInfo=0x1aaf40 {NSLocalizedDescription=Cannot连接到iTunes Store}

Question

目前，我正在开发应用程序中的购买功能，并且正在了解下面的错误。

"Error Domain=SKErrorDomain Code=3“无法连接到iTunes存储”UserInfo=0x1aaf40 {NSLocalizedDescription=Cannot连接到iTunes Store}"

这是第一步。

1)首先，我创建了一个应用程序"inAppPro“，它位于(Status)：”准备上传“下面

​

​

2)我增加了4件非消费品。并填写相关细节。

​

​

3)我还创建了测试用户(沙箱)的测试应用程序购买产品。

4)我还创建了支持inApp购买的供应配置文件。

5)我还创建了没有(*)外卡的应用程序ID。

这是我目前正在使用的代码。

- (void)viewDidLoad
{
   Detail1 *observer = [[Detail1 alloc] init];

   [[SKPaymentQueue defaultQueue] addTransactionObserver:observer];

   [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
}


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

    if ([SKPaymentQueue canMakePayments])
    {
        NSString *product = [NSString stringWithFormat:@"com.companyname.inAppDemo.module%d",ApplicationDelegate.objectID];
        NSLog(@"In-App product for request = %@", product);

        SKPayment *payment = [SKPayment paymentWithProductIdentifier:product];
        [[SKPaymentQueue defaultQueue] addPayment:payment];


    }
    else
    {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"MyApp" message:@"You are not authorized to purchase from AppStore"
                                                       delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
        [alert show];
        [alert release];
    }
}
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
    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) failedTransaction: (SKPaymentTransaction *)transaction
{   
    if (transaction.error.code != SKErrorPaymentCancelled)      
    {       
        // Optionally, display an error here.   
        NSLog(@"%@",transaction.error);

    }   
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction]; 
}

- (void) completeTransaction: (SKPaymentTransaction *)transaction
{       
    //[[MKStoreManager sharedManager] provideContent: transaction.payment.productIdentifier];   
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction]; 
}

- (void) restoreTransaction: (SKPaymentTransaction *)transaction
{   
    //[[MKStoreManager sharedManager] provideContent: transaction.originalTransaction.payment.productIdentifier];   
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction]; 
}
-(IBAction)btnpurchase:(id)sender
{
    NSLog(@"ProductStatus = %@", ApplicationDelegate.productStatus);

    if ([ApplicationDelegate.productStatus isEqualToString:@"FREE"]) 
    {
        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:nil message:@"This is free for you so ENJOY it!!!" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil,nil];
        [alert show];
        [alert release];
    }
    else if ([ApplicationDelegate.productStatus isEqualToString:@"PAID"]) 
    {
        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:nil message:@"You have already purchase it!!!" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil,nil];
        [alert show];
        [alert release];
    }
    else
    {
        NSLog(@"Detail1 id for product = %d", ApplicationDelegate.objectID);
        NSString *product = [NSString stringWithFormat:@"com.companyname.inAppDemo.module%d",ApplicationDelegate.objectID];
        NSLog(@"In-App product-id = %@", product);



        SKProductsRequest *request= [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObjects:product,nil]]; 
        request.delegate = self;
        [request start];

    }
}

请大家帮帮我。

提前谢谢。

您必须有有效的合同，在“合同，税收和银行业务”部分。当然，确保您使用了正确的配置文件，并且您已经在App中启用了该ID，并且(最后)您在iTunes连接中添加了可购买的项目(正如屏幕截图所示)。
