SKProductsRequestDelegate失败

Question

SKProductsRequestDelegate有一个方法：

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

通常，我发现这些类型的代表将有多种方法来处理多个案例，而不仅仅是成功。例如：

-(void) connection:(NSURLConnection *)connection didFailWithError:(NSError *) error

如何检查此代码是否由于某种原因而失败，例如。用户离线了吗？

SKProductsRequest *productsRequest = [[SKProductsRequest alloc] ... ];
productsRequest.delegate = self;
[productsRequest start];

Answer 1

SKProductsRequestDelegate符合SKRequestDelegate协议。

你找到了

- (void)request:(SKRequest *)request didFailWithError:(NSError *)error
- (void)requestDidFinish:(SKRequest *)request
