Question

UITableView has the method rectForRowAtIndexPath:, but this does not exist in UICollectionView. I’m looking for a nice clean way to grab a cell’s bounding rectangle, perhaps one that I could add as a category on UICollectionView.

Answer 1

The best way I’ve found to do this is the following:

Objective-C

UICollectionViewLayoutAttributes *attributes = [self.collectionView layoutAttributesForItemAtIndexPath:indexPath];

Swift

let attributes = collectionView.layoutAttributesForItem(at: indexPath)

Then you can access the location through either attributes.frame or attributes.center
