如何在UICollectionView中添加节标题？ [英] How do I add a section title in UICollectionView?

问题描述

我的Collection View中的每个部分都需要一个标签。我试过简单地将标签拖到原型单元格上方的标题空间中，但每次运行应用程序时，标签都不可见。

I need a label above every section in my Collection View. I've tried simply dragging a label into my header space above my prototype cell, but every time I run the app, the label is not visible.

任何帮助？

推荐答案

实施 collectionView：viewForSupplementaryElementOfKind：atIndexPath：并提供包含标签的出列UICollectionElementKindSectionHeader。如果这是流布局，请务必设置 headerReferenceSize ，否则您仍然看不到任何内容。

Implement collectionView:viewForSupplementaryElementOfKind:atIndexPath: and supply a dequeued UICollectionElementKindSectionHeader containing your label. If this is a flow layout, be sure also to set the headerReferenceSize or you still won't see anything.
