如何在iOS 13集合视图中隐藏标题合成布局

class CustomFlowLayout: UICollectionViewFlowLayout {
    override func shouldInvalidateLayout(forBoundsChange newBounds: CGRect) -> Bool {
        return true
    }
    
    override func layoutAttributesForElements(in rect: CGRect) -> [UICollectionViewLayoutAttributes]? {
        let attributes = super.layoutAttributesForElements(in: rect)
        
        for attribute in attributes ?? [] {
            if attribute.representedElementKind == UICollectionView.elementKindSectionHeader {
                attribute.frame = CGRect.zero
            }
        }
        
        return attributes
    }
}

let customFlowLayout = CustomFlowLayout()
collectionView.collectionViewLayout = customFlowLayout

override func viewDidLoad() {
    super.viewDidLoad()
    
    // 其他设置
    
    collectionView.register(UICollectionViewCell.self, forCellWithReuseIdentifier: "Cell")
    collectionView.backgroundColor = UIColor.white
    collectionView.showsVerticalScrollIndicator = false
    collectionView.showsHorizontalScrollIndicator = false
}
