是否在集合视图中选择单元格时快速设置下划线条动画？

// 在集合视图的委托方法中获取选中的单元格索引路径
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
    // 创建下划线视图
    let underlineView = UIView(frame: CGRect(x: 0, y: 0, width: collectionView.bounds.width, height: 2))
    underlineView.backgroundColor = UIColor.red
    
    // 将下划线视图添加到选中的单元格上
    let selectedCell = collectionView.cellForItem(at: indexPath)
    selectedCell?.contentView.addSubview(underlineView)
    
    // 设置下划线视图的初始位置
    underlineView.frame.origin.y = selectedCell?.bounds.height ?? 0
    
    // 执行下划线视图的动画效果
    UIView.animate(withDuration: 0.3, animations: {
        underlineView.frame.origin.y = selectedCell?.bounds.height ?? 0 - underlineView.bounds.height
    }) { (_) in
        // 动画完成后执行其他操作，如取消下划线视图的显示
        underlineView.removeFromSuperview()
    }
}
