我怎样才能在应用中购买SKProductsResponse invaild ID

Question

嘿伙计们，我很沮丧从iTunesConnect检索产品，但它总是返回无效ID。我满足所有要求，但没有得到任何回应。我按照这些步骤，我的答案是肯定的.. 请给我一些解决方案来解决这个问题。提前谢谢..

1.Have you enabled In-App Purchases for your App ID?
2.Have you checked Cleared for Sale for your product?
3.Have you submitted (and optionally rejected) your application binary?
4.Does your project’s .plist Bundle ID match your App ID?
5.Have you generated and installed a new provisioning profile for the new App ID?
6.Have you configured your project to code sign using this new provisioning profile?
7.Are you building for iPhone OS 3.0 or above?
8.Are you using the full product ID when when making an SKProductRequest? Have you waited several hours since adding your product to iTunes Connect?
9.Are your bank details active on iTunes Connect? (via Mark) Have you tried deleting the app from your device and reinstalling? (via Hector, S3B, Alex O, Joe, and Alberto)

代码：

-(void)fetchAvailableProducts{
    NSSet *productSet = [NSSet setWithObjects:@"com.magazineapp.books",nil];
    productsRequest = [[SKProductsRequest alloc]
                       initWithProductIdentifiers:productSet];
    productsRequest.delegate = self;
    [productsRequest start];
}

- (BOOL)canMakePurchases
{
    return [SKPaymentQueue canMakePayments];
}
- (void)purchaseMyProduct:(SKProduct*)product{
    if ([self canMakePurchases]) {
        SKPayment *payment = [SKPayment paymentWithProductIdentifier:product];
        [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
      //  [[SKPaymentQueue defaultQueue] addPayment:payment];
    }
    else{
        UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:
                                  @"Purchases are disabled in your device" message:nil delegate:
                                  self cancelButtonTitle:@"Ok" otherButtonTitles: nil];
        [alertView show];
    }
