ios - 一个控制器可以是一个tableview和collectionview的数据缘和代理吗？

Question

如题 我这样写了 但是显示加载不到collectioncell

Answer 1

It’s okay.
Collectioncell cannot be loaded. It should be that your collectionview is useless. It is recommended to search for relevant information and check it

Answer 2

No problem at all

Answer 3

There is no interference between dataSource and delegate. When tableView needs data, it calls the corresponding method of its own dataSource to obtain the cell. Whether the other party implements the collectionview proxy has nothing to do with it. There should be something wrong with your collectionView method
