Подобный ответ имеет похожий ответ, но я добавляю свой код, поскольку он уже проверяет canSendMail Я также оставил комментированный код, который позволяет легко добавлять другие материалы в электронное письмо.
Обратите внимание, что это значительно проще, если вы ориентируетесь только на iOS 5.
У меня есть бесплатное приложение QCount, которое использует этот код. Действительно, я надеюсь, что я удалил все пользовательское из моего копирования и вставки :-) http://itunes.apple.com/ng/app/qcount/id480084223?mt=8
Наслаждайтесь,
