iOS swift collectionview 瀑布流加载，实现这样的布局，每个cell里面的按钮要怎么动态加载进去？

Question

Thank you for the invitation. I can only say that this blank will not appear under normal circumstances. I have never seen this blank.

From the picture, you should be using the waterfall layout, which is the layout you wrote yourself. I guess there is something wrong with this layout. You can check it~
