Hello I am trying to set up in app purchases for ios 5 and newly ios 6. I am being told that my "paymentWithProductIdentifier is deprecated" and I was wondering if someone could tell me how to modify my code, I am a little confused.

您好，我正在尝试为 ios 5 和新的 ios 6 设置应用程序购买。有人告诉我我的“paymentWithProductIdentifier 已弃用”，我想知道是否有人可以告诉我如何修改我的代码，我有点困惑。

  SKProduct *selectedProduct = <#from the products response list#>;
  SKPayment *payment = [SKPayment paymentWithProduct:selectedProduct];
 [[SKPaymentQueue defaultQueue] addPayment:payment];

I have seen people suggest the following but I am not sure from my code what "the products response list would be". I thought it would be but its not.

我看到有人提出以下建议，但我从我的代码中不确定“产品响应列表是什么”。我以为会是，但不是。

 [response.products];

Here is my code for the method, if anyone can tell me what to change it would be appreciated thanks!

这是我的方法代码，如果有人能告诉我要更改什么，将不胜感激，谢谢！

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

   { 

 SKProduct *validProduct = nil;

 int count = [response.products count];

NSLog (@"count for in app purchases is %d", count);

 if (count>0) {

    validProduct = [response.products objectAtIndex:0];
    SKPayment *payment = [SKPayment paymentWithProductIdentifier:@"appUpdate1"];

    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    [[SKPaymentQueue defaultQueue] addPayment:payment]; // <-- KA CHING!

     NSLog (@"payment proccessed I think");
 }
 }

It looks like you're assuming that there is only one product, which you set to validProduct. You should be able to use

看起来您假设只有一种产品，您将其设置为 validProduct。你应该可以使用

SKPayment *payment = [SKPayment paymentWithProduct:validProduct]

The productIdentifier is a property of the SKProduct, so this method creates the new payment object with the identifier it gets from the SKProduct.

productIdentifier 是 SKProduct 的一个属性，因此此方法使用从 SKProduct 获取的标识符创建新的支付对象。
