ios – 在UICollectionViewCell中添加UICollectionView

我正在使用 Swift为我工作的医院构建一个iOS应用程序.

不知何故,在一个特定的功能中,我必须在UICollectionViewCell中放置一个UICollectionView.我想要实现的是父UICollectionView(垂直滚动)的每个内容都有几个子节点(可以水平滚动),具体取决于父行.

为了说明,我必须显示医生名单(姓名和照片),然后我必须在他们的名字和照片下方显示他们的每个练习时间表.实践时间表因每位医生而异.所以,我必须将它放在UICollectionView中.

我尝试过在网上找到的几种解决方案,但我仍然无法接近它.

我无法解决的最大问题是：我不知道代码中加载子数据源(医生日程安排)的位置以及何时可以加载它,因为我不能有两个函数,如下所示：

collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell

这是我想要实现的目标

UIImage和医生名称(UILabel)在父UICollectionViewCell(垂直滚动)中,然后框中的所有内容(练习日n练习时间)都是子UICollectionView(水平滚动)

PS：有很多医生,每个医生都有几天练习.

请帮我怎么做

如果你真的想在collectionViewCell中插入一个collectionView,那么有一个非常简单的步骤.创建UICollectionView的实例并将其添加到collectionViewCell.如果您愿意,可以使用此示例.
