## What it is
Source code repository accompanying the eBook 'A Guide to iOS Animation', containing 14+ Objective-C and Swift demos covering bezier curves, Core Animation, UIKit Dynamics, and animation math. It serves as the practical companion to a paid interactive book on iOS animation techniques.

## Use cases
- learn iOS animation techniques from worked examples
- study Core Animation demos like transitions and loading indicators
- understand bezier curve animations such as QQ bubble drag interactions
- recreate effects like Twitter launch animation or tvOS card tilt
- learn UIKit Dynamics and gravity bounce effects
- find reference code for custom property animations

## When to choose
- you are learning iOS animation and want hands-on demo code
- you want to dissect real implementations of popular app animations
- you prefer learning through interactive books with runnable examples

## When to avoid
- you need a production-ready animation library to drop into your app
- you work outside iOS/Apple platforms
- you need actively maintained code with recent updates

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: animation, ui-components, graphics, developer-tools
- domain: mobile-development, tutorials, web-design, graphics
- platform: -
- tags: ios-animation, core-animation, ebook, objective-c, swift, bezier-curves, uikit-dynamics, demo-code, ios, mobile
