Я новый разработчик приложений для iPhone.Мое приложение не работает, когда я нажимаю кнопку «Удалить» с симулятора в iPhone.Я скопировал некоторый код из моего проекта здесь.Я надеюсь, что смогу исправить ошибку, если это возможно.Я устал уже найти эту проблему, надеюсь, поможет мне решить.
мой код здесь.
