我如何获得 UICollectionView 的 rect [英] How do I get rect for UICollectionView

问题描述

我想在 UICollectionView 中定位部分标题的框架.我对 UITableView 有类似的情况，为此，我可以通过以下方式获得它的 rect:

I want to locate the frame of section header in UICollectionView. I have a similar situation for UITableView, and for that, I was able to get its rect by doing:

 CGRect rect = [self.tableView rectForHeaderInSection:section];

有没有办法在 UICollectionView 中获得相同的结果?谢谢！

Is there a way to get the same result in UICollectionView? Thanks!

抱歉，各位.其实很简单.

Sorry, guys. It was actually easy.

 NSIndexPath *indexPath = [NSIndexPath indexPathForItem:0 inSection:section];
 UICollectionViewLayoutAttributes *attributes = [self.collectionView layoutAttributesForSupplementaryElementOfKind:UICollectionElementKindSectionHeader atIndexPath:indexPath];
 CGRect rect = [attributes frame];
