Мой переключатель не сбрасывается при вызове clearbtn, он просто остается в том же состоянии.Также, когда я вызываю pushme и проверяю, включен ли выключатель, он всегда обнаруживает его выключение, что может быть причиной этого?Как я могу это исправить?Я создал приложение на основе Windows, просто чтобы поиграть, я еще не создал UIViewController, это то, что вызывает эту проблему?Спасибо.
