问题描述

I have a UICollectionView and only one section. Is there a way to set the background color of every row? (in my case it would be a gradient from black to white)

推荐答案

CollectionViews实际上没有行的概念，因为它被设计为具有灵活的布局.

CollectionViews don't really have a concept of a rows because it's designed to have a flexible layout.

您最好的选择可能是使单元格的背景具有您的图案，并删除单元格之间的所有填充/边距.

Your best option is likely to have the background of the cells have your pattern and remove all the padding/margin between the cells.

如果最后一行未满，这将是一个问题，因此，如果数字需要灵活，则必须添加空单元格.

This will be a problem if the last row isn't full, so if the number needs to be flexible you would have to add empty cells.
