Я пытаюсь загрузить изображение профиля в твиттер, используя их API. Я нашел несколько хороших примеров в Интернете о том, как отформатировать URLRequest, однако я просто не могу заставить это работать. Любая помощь будет оценена. URL, который я использую в Twitter API: http://twitter.com/account/update_profile_image.json
