UIScrollView與UICollectionView

Question

我有UIScrollView和UICollectionView。在CollectionView中，它是25張100x100大小的圖像。當我運行我的應用程序時，顯示模擬器中的前12個圖像，然後向上滾動，然後顯示下一個圖像。那不是我的問題。我想以水平模式而不是垂直模式顯示圖像。意味着在第一頁顯示的12張圖像然後滾動水平，並顯示下一個圖像不垂直。請告訴我如何去做。

謝謝。

你需要用它來取代你（評論）scrolldirection：

[FlowLayout中setScrollDirection：UICollectionViewScrollDirectionHorizo​​ntal]。
