苹果应用内购买

Question

在设备上测试SANDBOX环境中的应用内购买时，我记录了以下错误： Error Domain=SKErrorDomain Code=0 "Cannot connect to iTunes Store" UserInfo=0x2916a0 {NSLocalizedDescription=Cannot connect to iTunes Store}. 我能够检索通过iTunes Connect注册的产品ID。我在表视图中显示与这些产品相关的数据，并提供购买选项。当我尝试购买产品时，会启动交易，但它不会要求我输入任何测试用户详细信息，并且我会收到如上所述的错误。

我提供了我实现的代码。

    //the below code is for RETREIVING THE PRODUCT id's

#pragma mark Store kit
-(IBAction)sendProductInfoRequest{
NSLog(@"sendProductInfoRequest");

NSSet *identifiersSet=[NSSet setWithObjects:[NSString stringWithFormat:@"%@",@".15April2011"],[NSString                          stringWithFormat:@"%@",@"15April201102"],nil];
SKProductsRequest *productRequest=[[SKProductsRequest alloc] initWithProductIdentifiers:identifiersSet];
productRequest.delegate=self;
[productRequest start];
NSLog(@"completing sendProductInfoRequest");
}

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
NSLog(@"yoooo!");
NSLog(@"The product request didReceiveResponse :%@",[response description]);
NSLog(@"The products are :%@",[response.products description]);

NSLog(@"The invalidProductIdentifiers are:%@",[response.invalidProductIdentifiers description]);

NSArray *products=response.products;



for(SKProduct *currentProduct in products){

NSLog(@"THE Product price is :%@",currentProduct.price);
NSLog(@"THE Product description is :%@",currentProduct.localizedDescription);
NSLog(@"THE Product title is :%@",currentProduct.localizedTitle);
NSLog(@"THE Product's product identifier is :%@",currentProduct.productIdentifier);

}

}



/the BuyProducts method is called when user clicks buy button related to a particular product
-(IBAction)BuyProducts
{
if ([SKPaymentQueue canMakePayments])
{
[self makePaymentRequestForThisProduct:isbnText.text];
}

}



-(void)makePaymentRequestForThisProduct:(NSString*)productID

{
SKPayment *payment = [SKPayment paymentWithProductIdentifier:productID];  
[[SKPaymentQueue defaultQueue] addPayment:payment];
}

您没有互联网连接吗？ - Richard H

@richard 我正在获取我在iTunes Connect注册的所有应用程序的产品信息。这意味着我的Wi-Fi连接是活动的。 - Pranav Jaiswal

抱歉重新提出一个旧问题，但我现在遇到了完全相同的问题，除了硬重置之外，您能找到其他解决方案吗？ - Can Poyrazoğlu

说句实话，我也遇到了完全相同的问题。我发现，至少对我来说，原因是我的设备登录了真实的苹果账户而不是测试账户。我注销了账户，然后一切都正常工作了。 - John Gaby

Answer 1

这可能听起来很荒谬，但如果你确定你的代码是正确的，那就对你的iPod进行硬重置（完全擦除）（设置=>通用=>重置=>清除所有内容和设置）。

沙盒服务器有可能宕机了吗？你不认为我在这里附加的代码是正确的吗？ - Pranav Jaiswal

Answer 2

如果您使用其他iTunes帐户登录，也会发生这种情况。要在沙盒框中测试应用内购买，您需要从设置中注销任何其他帐户。然后启动您的应用程序并进行应用内购买。当要求输入您的帐户时，请输入您创建的iTunes测试帐户。这样，您的沙盒环境将完美运行。希望这对您有所帮助。

Answer 3

可能是沙盒服务器出了问题。

我可以获取产品信息，但在请求购买时会出现同样的错误。

我查看了苹果开发者论坛，发现更多人遇到了相同的问题。 https://devforums.apple.com/index.jspa

希望这能为某些人节省时间，因为我已经花了4个小时在这上面了。
