## What it is
PSCollectionView is an Objective-C library implementing a Pinterest-style pinboard (waterfall) scroll view for iOS, used similarly to UITableView. It supports portrait/landscape column counts, header/footer views, and subclassable cells with delegate/dataSource patterns.

## Use cases
- build a Pinterest-style waterfall grid in an iOS app
- display variable-height cards in multiple columns
- create a masonry image feed like a pinboard
- use a UITableView-like API for a multi-column scroll view
- show different column counts for iPhone and iPad

## When to choose
- you are maintaining a legacy Objective-C iOS app needing a simple Pinterest-style layout
- you want a lightweight UITableView-style API for a waterfall grid

## When to avoid
- starting a new Swift project — use UICollectionViewCompositionalLayout or a modern masonry library instead
- you need actively maintained code with recent iOS support
