在IOS6中,我在我的应用中成功进行了应用内购买.

我下载了IOS /和Xcode 5 Beta并尝试打开同一个项目.

从app store获取产品的代码是:

- (void)requestProductsWithIdentifiers:(NSSet*)identifiers
{
        @synchronized(self)
    {
            DebugLog(@"requesting products with identifiers: %@", identifiers);

            self.productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:identifiers] ;
            self.productsRequest.delegate = self;
            [self.productsRequest start];
    }
}

但它返回一个错误:

[IAPHelper request:didFailWithError:](114): request did fail with error: <SKProductsRequest: 0xb846a10> / Error Domain=SSErrorDomain Code=2 "Cannot connect to iTunes Store" UserInfo=0xb846b10 {NSLocalizedDescription=Cannot connect to iTunes Store}

哪里可以问题？
