How to parse Array answer from server

Question

This is the answer I get from API:

- (void)postRequestWithHeader:(NSString *)url
     parameters:(NSDictionary *)parameters
     completionHandler:(void (^)(NSDictionary *data, NSError *))completionHandler
    {
NSString *URLString = [NSString stringWithFormat:@"%@%@", baseURL, url];


NSMutableURLRequest *request= [[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters error:nil];
  NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];

NSString *session =[[LocalDataBase sharedDataBase]userDataObjectForKey:@"session"];
[request setValue:session forHTTPHeaderField:@"session"];


NSURLSessionDataTask *dataTask = [manager dataTaskWithRequest:request
                                            completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
                                                NSDictionary *backParam = [[AFHTTPResponseSerializer serializer] responseObjectForResponse:responseObject data:responseObject error:nil];

                                                if (error) {
                                                    NSLog(@"Error: %@", error);
                                                    completionHandler(nil, error);
                                                } else {
                                                    if ([responseObject isKindOfClass:[NSArray class]]) {
                                                        NSLog(@"response is in array");
                                                                                                                     }else {
                                                    NSLog(@"%@ %@", response, responseObject);
                                                    completionHandler(backParam, nil);
                                                    }
                                                    ;}
                                            }];
[dataTask resume];



    }


-(void) requestForPosts:(void (^)(NSError *error))completionHandler
   {

[self postRequestWithHeader:@"posts/list"
             parameters:nil
      completionHandler:^(NSDictionary *data, NSError *error)  {
    if (error) {
        NSLog(@"Error: %@", error);
        completionHandler(error);
    } else {
        NSLog(data);
       // [[LocalDataBase sharedDataBase] saveUserData:data];
        completionHandler(nil);
    }

}];
}

This is code i use to send request for API and then i get response and check if it is array, but i don't know what tot do after this I need to get this response and put into table view/ I hope someone will help me)

Hint: That response is in JSON format. – Droppy Aug 12 '16 at 14:31 — Droppy, Aug 12 '16 at 14:31

Your webservice gives you a json response.

In your completion block, the parameter data is not of kind NSDictionary but NSArray*

[[AFHTTPResponseSerializer serializer] responseObjectForResponse:responseObject data:responseObject error:nil]

did already parse the object for you in an NSArray, not into a NSDictionary...

How do I parse JSON with Objective-C?

The assumption that the OP is using AF networking is unwarranted. I think the better response is to vote to close as a very frequent duplicate. – danh Aug 12 '16 at 15:03

I think he is: AFHTTPResponseSerializer & AFURLSessionManager are mentionned in the question post :) – Florian Burel Aug 12 '16 at 15:19
Oh. There it is. My apologies. – danh Aug 12 '16 at 15:21
