Не удалось выполнить сериализацию JSON Objective-c

У меня проблема. Когда я пытаюсь выполнить тест my json, он говорит, что это неверно. Но когда я тестирую его с помощью онлайн-сервисов, он читает его хорошо.Не удалось выполнить сериализацию JSON Objective-c

код я использую, чтобы проверить, если JSON является действительным является:

NSString* stringRes = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; 
[NSJSONSerialization isValidJSONObject:stringRes];

Где stringRes сын строка в формате NSString (Из ответа данных) JSON:.

UPD: решаемые используя

NSData* data = [stringRes dataUsingEncoding:NSUTF8StringEncoding];

источник

isValidJSONObject проверяет, является ли объект JSON (NSDictionary или NSA rray) можно успешно преобразовать в данные JSON.

Это не для тестирования, если объект NSData содержит действительные данные JSON. Для проверки достоверных данных JSON вы просто позвоните

[NSJSONSerialization JSONObjectWithData: данные ...]

и проверить, если возвращаемое значение равно нулю или нет.

Хе-хе ... Я использовал это раньше, и это сломало мое приложение ... Тогда я решил проверить его. –

NSArray * dict = [NSJSONSerialization JSONObjectWithData: stringRes options: NSJSONReadingMutableLeaves error: & error]; –

Не удалось выполнить сериализацию JSON Objective-c
