Коллекция iOS 7 Просмотр Scroll View
Я использую раскадровку для разработки приложения, которое имеетUICollectionView внутриUIScrollView, Я установил делегата иdataSource в раскадровке и коде.
Я помещаю поддельную информацию, чтобы проверить макет приложения, ноUICollectionView а такжеUICollectionViewCell никак не появляются.
