[collectionView scrollToItemAtIndexPath:[NSIndexPath indexPathForRow:2 inSection:3] atScrollPosition:UICollectionViewScrollPositionCenteredHorizontally animated:YES]，调用之后collectionview不移动是怎么回事？

我这儿看了，没问题呀，你是否参数弄错了，UICollectionViewScrollPositionCenteredHorizontally 水平方向的中心
UICollectionViewScrollPositionCenteredVertically 垂直方向的中心
