Это улучшение скрипта «Создать свойство и синтез для переменных экземпляра», который Лоуренс Джонстон разместил выше.
Настройки:
Ввод: весь документ
Каталог: Домашний каталог
Выход: Отменить вывод
Ошибки: игнорировать ошибки (или оповещения, если вы хотите их видеть)
Выберите любое количество переменных, и он создаст свойства и syns для всех них. Он даже создаст / отредактирует ваш метод dalloc по мере необходимости.
Редактировать результаты, если они не совсем правильные (копировать или сохранить и т. Д.)
Обрабатывает больше вещей, таких как имя хранилища в нижней части, поведение, освобождение,…
