## What it is
Leaves is an Objective-C iOS library providing an animated page-turning interface for navigating sequences of images with page-curl gestures. It is largely obsoleted by UIPageViewController since iOS 5 and has not been updated since 2017.

## Use cases
- add iBooks-style page curl animation to an iOS app
- build an image-based book or magazine reader on iOS
- implement swipe-to-turn-page navigation between rendered pages
- create a two-page spread view like a physical book on iPad

## When to choose
- you must support very old iOS versions (pre-iOS 5) with page-curl effects
- you need a customizable page-turn view that UIPageViewController cannot replicate

## When to avoid
- you target modern iOS - use UIPageViewController instead
- you need ARC, Retina, or Swift support without extra forking
- you want an actively maintained dependency

## Facets
- artifact type: library
- maturity: abandoned
- function: ui-components, animation
- domain: mobile-development, frontend
- platform: -
- tags: page-turn, objective-c, uikit, ebook-reader, page-curl, ios, mobile
