我无法纵向和横向滚动以使用NSCollectionView的自定义布局.根据文档,在我的子类中,我返回`collectionViewContentSize',如果它太大,则在集合视图的封闭滚动视图中自动启用滚动.但是,即使我在水平行中排序所有元素,也只启用垂直滚动.

这是我的布局代码:

import Cocoa 
class Layout: NSCollectionViewLayout {

var cellSize = CGSize(width: 100, height: 30)

var cellSpacing: CGFloat = 10
var sectionSpacing: CGFloat = 20

private var contentSize = CGSize.zero
private var layoutAttributes = [NSIndexPath: NSCollectionViewLayoutAttributes]()


override func prepareLayout() {
    guard let collectionView = collectionView else { return }

    let sections = collectionView.numberOfSections
    guard sections > 0 else { return }

    contentSize.height = cellSize.height

    for section in 0..<sections {
        let items = collectionView.numberOfItemsInSection(section)
        guard items > …
