## What it is
An Objective-C library that decodes and encodes animated GIFs as UIImage objects on iOS, following NSJSONSerialization-style API conventions. It optionally swizzles UIImage initializers so animated GIFs load automatically, though it is no longer maintained in favor of CGAnimateImageAtURLWithBlock.

## Use cases
- display animated gif images in a uiimageview on ios
- decode animated gif data into uiimage
- encode a uiimage as an animated gif file
- load animated gifs with uiimage imagenamed

## When to choose
- you must support iOS versions older than 13 where CGAnimateImageAtURLWithBlock is unavailable
- you need NSJSONSerialization-style GIF encoding/decoding in Objective-C

## When to avoid
- you target iOS 13+ or macOS 10.15+, where Apple's CGAnimateImageAtURLWithBlock is the supported solution
- you want an actively maintained library
- you dislike method swizzling in your codebase

## Facets
- artifact type: library
- maturity: abandoned
- function: image-processing, serialization
- domain: image-processing, mobile-development
- platform: -
- tags: animated-gif, objective-c, uiimage, method-swizzling, deprecated, ios, macos, swift
