Objective c 无法连接到iTunes存储错误代码0

我试图遵循这一点，但我得到了一个错误：

Error Domain=SKErrorDomain Code=0 "Cannot connect to iTunes Store" UserInfo=0x15c02260 {NSLocalizedDescription=Cannot connect to iTunes Store}

我已经在iTunes Connect中创建了一个测试用户，但是连接到新用户的弹出窗口甚至没有显示出来。我已经尝试重置模拟器，从模拟器中删除应用程序，从应用程序支持文件中删除文件，以及在其他主题中提供的有关此错误的其他解决方案

我的最后一个假设是，我的代码在某种程度上是错误的，我没有看到

这是我的代码：

-(id)init
{

 if (self = [super init]) {

 NSLog(@"game store loaded");


 if ([SKPaymentQueue canMakePayments])
 {
 NSLog(@"can make payments");
 SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers: [NSSet setWithObject:@"teste2"]];
 productsRequest.delegate = self;
 [productsRequest start];

 //start Buying/buy button
 //SKProduct *selectedProduct = @"teste2";
 //SKPayment *payment = [SKPayment paymentWithProduct:selectedProduct];
 SKPayment *payment = [SKPayment paymentWithProductIdentifier:@"com.rundogrun.prod001"];
 [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
 [[SKPaymentQueue defaultQueue] addPayment:payment];

 }
 else {
 NSLog(@"Please enable In App Purchase in Settings");
 }





 }



 return self;

}


-(void)productsRequest:(SKProductsRequest *)request didReceiveResponse: (SKProductsResponse *)response {
 SKProduct *validProduct = nil;
 int count = [response.products count];
 if (count > 0) {
 NSLog(@"%d products available", count);
 validProduct = [response.products objectAtIndex:0];
 } else if (!validProduct) {
 NSLog(@"No products available");
 }

}

-(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {
 for (SKPaymentTransaction *transaction in transactions) {
 switch (transaction.transactionState) {
 case SKPaymentTransactionStatePurchasing:
 NSLog(@"purchasing");
 //avisa usuario que o produto esta sendo comprado
 break;
 case SKPaymentTransactionStatePurchased:
 NSLog(@"purchased");
 //faz alguma coisa quando o produto for comprado

 [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
 break;
 case SKPaymentTransactionStateRestored:
 NSLog(@"restored");
 [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
 break;
 case SKPaymentTransactionStateFailed:
 NSLog(@"failed");
 if (transaction.error.code != SKErrorPaymentCancelled) {
 NSLog(@"An Error Encoutered %@", transaction.error.description );
 }
 [[SKPaymentQueue defaultQueue] finishTransaction:transaction];

 default:
 break;
 }

 }

}

在iOS 7中，IAP不能在模拟器中工作。我在设备上运行，它工作得很好

您使用的是什么版本的iOS？IAP在iOS7模拟器上不工作。是的，我看到了。谢谢你的回答
