ios - 如何将选项集作为滚动位置的参数传递？

Question

我想将滚动位置的选项集作为参数参数传递，但遇到了一些问题。

谁能写出怎么做？

func selectCurrentWallpaperCell() { //want to pass parameter here
        let currentWallpaperID = self.wallpaperManager.currentWallpaperID
        if let index = self.wallpapers.index(where: { $0.id == currentWallpaperID }) {
            let indexPath = IndexPath(item: index, section: 0)
            self.collectionView.selectItem(at: indexPath, animated: true, scrollPosition: UICollectionViewScrollPosition()) // how to use in scrollposition?
        }
    }

Answer 1

let options: UICollectionViewScrollPosition = [.top, .centeredVertically]
self.collectionView.selectItem(at: indexPath, animated: true, scrollPosition: options)
