## What it is
An Objective-C framework for loading, caching, processing, displaying, and preheating images on iOS. It is no longer maintained; the author recommends its Swift successor, Nuke.

## Use cases
- load and display remote images in an iOS app
- cache images with memory and HTTP caching layers
- resize and crop images to fit view sizes
- preheat images near the viewport for smoother scrolling
- decode progressive JPEGs and WebP images

## When to choose
- maintaining a legacy Objective-C iOS codebase that already uses it
- you need a zero-config image pipeline with preheating and cannot migrate

## When to avoid
- starting any new project - it is unmaintained
- you program in Swift - use Nuke instead
- you need ongoing bug fixes, security updates, or modern platform support

## Facets

- function: image-processing, caching, http-client
- domain: mobile-development, image-processing
- platform: -
