AFNetworking、NSURLSession、jsonレスポンス（Ronak Sankhala）

Question

ウェブサービスAPIからjsonレスポンスを取得しようとしています。私はjsonから製品データを抽出したい。私はまた、AFNetworkingを使用してこれを実装したいと思います。また、NSURLSessionを使用して応答を取得しようとしています。

} 

-(void)connectionString

NSURLSession *session = [NSURLSession sharedSession]; // its working

NSMutableDictionary *jsonResponse = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil]; 
    NSLog(@"%@", jsonResponse); 

    dataArray = [jsonResponse objectForKey:@"objEventcategoryList"]; 

    self.tblTableView.dataSource = self; 
    self.tblTableView.delegate = self; 

    [self.tblTableView reloadData]; 


    NSLog(@"JSON: %@", dataArray); 

}]; 

[dataTask resume]; 

// AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; // its working
