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几种处理多个案例的方法,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因某些原因失败,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
