“horizontal(layoutSize:subitem:count:)”在 iOS 16.0 中已弃用

Question

我使用 UICollectionViewCompositionalLayout 将我的集合视图项目并排放置以进行横向放置，并在正常心情下放置单个平铺。因此，我使用 NSCollectionLayoutGroups 来实现这个目标。当我定义我的组时，我收到了上述错误。我的代码如下。

private func layout() -> UICollectionViewCompositionalLayout {
    
    let layout = UICollectionViewCompositionalLayout { sectionIndex, environment -> NSCollectionLayoutSection? in
        
        let itemSize = NSCollectionLayoutSize (
            widthDimension: .fractionalWidth(0.2),
            heightDimension: .estimated(400)
        )
        let item = NSCollectionLayoutItem(layoutSize: itemSize)
        
        let groupSize = NSCollectionLayoutSize (
            widthDimension: .fractionalWidth(1.0),
            heightDimension: .estimated(400)
        )
        
        let columns = (environment.container.contentSize.width > 500 && self.toggleSwitch.isOn) ? 2 : 1
        
       //MARK: Error horizontal(layoutSize:subitem:count:)' was deprecated in iOS 16.0
        let group = NSCollectionLayoutGroup.horizontal(layoutSize: groupSize, subitem: item, count: columns)
        
        group.interItemSpacing = .fixed(20)
        
        if columns > 1 {
            group.contentInsets.leading = 20
            group.contentInsets.trailing = 20
        }
        
        let section = NSCollectionLayoutSection(group: group)
        section.interGroupSpacing = 20
        section.contentInsets.top = 20
        
        return section
    }
    
    let config = UICollectionViewCompositionalLayoutConfiguration()
    config.interSectionSpacing = 50
    layout.configuration = config
    
    return layout
}

它已被

horizontal(layoutSize:repeatingSubitem:count:)

取代，如 Apple 开发者网站 上所述。这是更新代码的方式：

let group = NSCollectionLayoutGroup.horizontal(layoutSize: groupSize, repeatingSubitem: item, count: columns)
