UIScrollView使用UICollectionView

Question

我有UIScrollView和UICollectionView。在CollectionView中，有25个100x100大小的图像。当我运行我的应用程序时，它在模拟器中显示前12个图像然后我向上滚动然后显示下一个图像。那不是我的问题。我想以水平模式显示图像而不是垂直模式。表示在第一页显示12个图像然后水平滚动，并显示下一个不垂直的图像。请告诉我如何操作。

感谢。

你需要用这个替换你的（注释的）scrolldirection：

[flowLayout setScrollDirection：UICollectionViewScrollDirectionHorizo​​ntal];
