У меня есть пользовательская ячейка для таблицы, работает нормально,
Я показываю список продуктов в ячейках, когда пользователь нажимает кнопку «удалить», я показываю предупреждение, чтобы подтвердить удаление,
но мне нужно показать название продукта в окне предупреждения: "are you sure you want to delete XXX?"
здесь код моей пользовательской ячейки
Обратите внимание на вызов в окне оповещения в deleteCartButtonPressed
