28. Requirements
29. Serializers
30. AFURLConnectionOperation AFHTTPRequestOperation AFJSONRequestOperation
31. - (void)setCompletionBlockWithSuccess:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure { #pragma clang diagnostic push #pragma clang diagnostic ignored "-Warc-retain-cycles" #pragma clang diagnostic ignored "-Wgnu" self.completionBlock = ^ { if (self.error) { if (failure) { dispatch_async(self.failureCallbackQueue ?: dispatch_get_main_queue(), ^{ failure(self, self.error); }); } } else { dispatch_async(json_request_operation_processing_queue(), ^{ id JSON = self.responseJSON; if (self.error) { if (failure) { dispatch_async(self.failureCallbackQueue ?: dispatch_get_main_queue(), ^{ failure(self, self.error); }); } } else { if (success) { dispatch_async(self.successCallbackQueue ?: dispatch_get_main_queue(), ^{ success(self, JSON); }); } } }); } }; #pragma clang diagnostic pop }
32. - (void)setCompletionBlockWithSuccess:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure { __weak __typeof(self)weakSelf = self; [super setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { __strong __typeof(weakSelf)strongSelf = weakSelf; if (![responseObject isKindOfClass:[NSData class]]) { [strongSelf setResponseJSON:responseObject]; } } failure:^(AFHTTPRequestOperation *operation, NSError *error) { __strong __typeof(weakSelf)strongSelf = weakSelf; [strongSelf setError:error]; }]; }
33. op.responseSerializer = [AFJSONSerializer serializer];
34. <AFURLRequestSerialization> <AFURLResponseSerialization> - requestBySerializingRequest: withParameters: error: - responseObjectForResponse: data: error:
35. • Shared Between Request Operations & Session Tasks • Significantly Reduced Boilerplate Code • Pluggable & Configurable • Protocol, Not Subclass Serializers
36. Built-in Serializers • HTTP • JSON • Property List • HTTP • JSON • XML Parser • XML Document (OSX) • Property List • Image Request Response
37. Serializer Extensions • MsgPack • CSV / TSV • vCard • vCal • WebP
38. Object Serialization • NSObject • NSManagedObject • RKManagedObject • MTLModel
41. Changes to AFHTTPRequestOperation • You'll Actually Use it Directly! • @property responseSerializer • @property completionQueue • @property completionGroup
42. NSURL *URL = [NSURL URLWithString:@"http://example.com/foo.json"]; NSURLRequest *request = [NSURLRequest requestWithURL:URL]; AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; operation.responseSerializer = [AFJSONSerializer serializer]; [operation start];
