iOS: 如何在 swift 3 中 select 并滚动到 collectionView 中的特定单元格？
iOS: How to select and scroll to a specific cell in a collectionView in swift 3?
我想 select 并滚动到 collectionView 中的特定 indexPath 并将其居中。我找到了这些功能，但无法将它们组合起来：
collectionView.selectItem(at: indexPath, animated: true, scrollPosition: UICollectionViewScrollPosition.centeredVertically)
collectionView.scrollToItem(at: indexPath, at: .centeredHorizontally, animated: true)
collectionView.scrollToItem(at: indexPath, at: .centeredVertically, animated: true)
提前致谢。
你可以传递选项集[.centeredHorizontally,.centeredVertically]
collectionView.scrollToItem(at: indexPath, at: [.centeredHorizontally,.centeredVertically], animated: true)
