                                         "callNativeDoSthing:",

  NSError *e = nil;
   NSData *information = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
   NSDictionary *jsonDictionary = [NSJSONSerialization JSONObjectWithData: data options:  
 NSJSONReadingMutableContainers error: &e];
   NSString* consumer=jsonDictionary["user"]
