AFNetworking : Re-use Method - ios

Question

We know that we can get return value from a normal method, for example :
-(NSString*)ASimpleFunction:(NSString*)str{
return str;
}
Calling this : [self ASimpleFunction:#"abc"] will return "abc".
If I have declared it in singleton class, so that I can use it from anywhere like:
+(NSString*)ASimpleFunction:(NSString*)str{
return str;
}
Calling it: [Singleton ASimpleFunction:#"xyz"] will return "xyz".
Hence above method, declared in Singleton class can be accessed/Re-used from anywhere by class name itself i.e. Singleton.
Similarly, I want to reuse the AFNetworking Method, I will pass NSDictionary of parameters , NSString for URL etc. But the thing is AFNetworking's Success and Failure blocks don't return values. So , I can't get reponseObject on success and error on failure in return.
Am I doing it right writing same code i.e, url, parameters, [success..]/[failure..] block again an again for each networking request?
Or is there is a good suggested architecture is available?
P.S - I have googled a lot for it but found nothing.

Here is how you can create your own helper class and use anywhere you can.
First let's create method to call AFNetworking response, success and failure:
+(void)getWebserviceWithURL:(NSString*)strUrl withParam:(NSDictionary*)dictParam withCompletion:(void(^)(NSDictionary*response))completion withFailure:(void(^)(NSDictionary*response))failure withLoadingText:(NSString*)text
{
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
AFJSONResponseSerializer *responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];
manager.responseSerializer = responseSerializer;
[manager GET:strUrl parameters:dictParam success:^(AFHTTPRequestOperation *operation, id responseObject) {
// [[Helper sharedInstance] dismissProgressBar];
completion(responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
failure([NSMutableDictionary dictionaryWithObjects:[NSArray arrayWithObjects:error, operation, nil] forKeys:[NSArray arrayWithObjects:#"error",#"operation", nil]]);
// [[Helper sharedInstance] dismissProgressBar];
}];
}
Now you can create your own method and get response, success and failure using the completion block:
- (void)WebSeries:(void(^)(bool status, NSMutableArray *seriesResponseData, NSString *compMessage))completion
{
//NSDictionary *dict = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:#"data", nil] forKeys:[NSArray arrayWithObjects:#"iComicBookId", nil]];
NSDictionary *dict = [NSDictionary dictionaryWithObject:#"1" forKey:#"fk_iWebSeriesId"];
[Helper postWebserviceWithURL:EPISODESURL withParam:dict withCompletion:^(NSDictionary *response) {
NSLog(#"%#",response);
NSMutableArray *webSeriesData = response[#"data"];
completion(YES, webSeriesData, response[#"msg"]);
} withFailure:^(NSDictionary *response) {
} withLoadingText:#"Loading"];
}
Hope this helps!
