## What it is
A UICollectionViewFlowLayout subclass for iOS that presents collection view cells with an overlapping, sticky stacking effect. Written in Objective-C, it is dropped into a project as a custom layout for any UICollectionView.

## Use cases
- create a stacked card deck interface in a collection view
- make collection view cells overlap and stick while scrolling
- build a tappable stack of photos or cards on iOS
- implement a Primer-style stacked list with UICollectionView
- customize scroll behavior of overlapping collection view cells

## When to choose
- you need overlapping/sticky cells in a UICollectionView on iOS
- your project is Objective-C or you prefer the original implementation
- you want a lightweight drop-in layout class without dependencies

## When to avoid
- you are starting a new Swift project - the Swift version (StickyCollectionView-Swift) is more appropriate
- you need a maintained library - the last release was in 2016
- you need non-iOS platforms or SwiftUI support
