如何设置集合视图快捷单元格的位置？

class MyViewController: UIViewController, UICollectionViewDelegateFlowLayout {
    // 创建集合视图
    let collectionView = UICollectionView(frame: CGRect.zero, collectionViewLayout: UICollectionViewFlowLayout())
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 设置代理和数据源
        collectionView.delegate = self
        collectionView.dataSource = self
        
        // 设置集合视图的布局
        let layout = collectionView.collectionViewLayout as! UICollectionViewFlowLayout
        layout.scrollDirection = .vertical
        
        // 设置单元格间距
        layout.minimumLineSpacing = 10
        layout.minimumInteritemSpacing = 10
        
        // 设置单元格位置
        layout.sectionInset = UIEdgeInsets(top: 10, left: 10, bottom: 10, right: 10)
    }
    
    // 实现代理方法
    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
        // 根据需求计算并返回每个单元格的大小
        return CGSize(width: 100, height: 100)
    }
    
    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets {
        // 设置每个节的内边距
        return UIEdgeInsets(top: 10, left: 10, bottom: 10, right: 10)
    }
}
