Создайте структуру Movie
и создайте массив кортежей в контроллере представления. В кортеже добавьте название категории и массив связанных фильмов. В методах источника данных табличного представления используется основной массив, а в методах источника данных табличного представления - массив movies из соответствующего кортежа. Установите текущий индекс кортежа / секции как тег collectionView
. И получите соответствующий массив фильмов в методах источника данных представления коллекции.
