Я использовал сегментный контроль внутри проекта.И при его выборе я отображаю данные моего табличного представления, но после загрузки ничего не отображается, но после нажатия кнопки все данные отображаются.Таким образом, проблема в том, что по умолчанию выбран мой сегментный контроль, но данные не заполняются в табличном представлении.Тем не менее, я использовал выбранный метод управления сегментами
