## What it is
An Objective-C iOS UI control that reveals side views with a paper-folding animation as the user drags the center view. It simulates folds by screen-capturing side views and applying lighting effects across fold segments.

## Use cases
- add a paper fold animation to an iOS side menu
- hide and reveal views on the left and right of the screen by dragging
- create a multi-fold right-side panel in an iOS app
- build a folding navigation UI like a newspaper fold
- add a draggable drawer with fold animation to a view controller

## When to choose
- you are building an older Objective-C iOS app and want a distinctive fold animation for side panels
- you need a lightweight, self-contained UI control with a sample project to start from

## When to avoid
- you are starting a new Swift or SwiftUI project, as the library is unmaintained since 2016
- you need vertical folds in production, since that feature remained experimental
- you need guaranteed license clarity, as the license is non-standard

- artifact type: library

- function: animation, ui-components
