ios - SKProductsRequestDelegate 失败

Question

SKProductsRequestDelegate 有一个方法：

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

通常，我发现这类代表会有几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失败，例如。用户离线？

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

Answer 1

SKProductsRequestDelegate符合SKRequestDelegate协议。

你在那里找到

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