你可以做

AFHTTPRequestOperation *requestOperation = [[AFHTTPRequestOperation alloc] initWithRequest:urlRequest]; requestOperation.responseSerializer = [AFImageResponseSerializer serializer]; [requestOperation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"Response: %@", responseObject); _imageView.image = responseObject; } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Image error: %@", error); }]; [requestOperation start];
