## What it is
A curated collection of iOS example projects and demos written primarily in Objective-C, covering AVFoundation camera/video capture and editing, face detection, real-time filters, GPUImage, OpenGL ES, WKWebView integration, crash protection, and APM monitoring. It also includes LeetCode algorithm practice and notes on common iOS development pitfalls.

## Use cases
- learn how to build a custom camera with AVFoundation like WeChat
- implement real-time video filters with GPUImage
- add face detection to an iOS app
- handle audio/video encoding and decoding with VideoToolbox
- integrate WKWebView with UITableView and offline caching
- protect an iOS app from crashes and monitor performance
- practice LeetCode algorithms in Objective-C
- adapt an app to dark mode and Sign in with Apple

## When to choose
- you are an iOS developer looking for working Objective-C examples of AVFoundation, GPUImage, or WKWebView techniques
- you want reference code for camera capture, video editing, or real-time filters
- you need sample implementations of crash protection or APM monitoring on iOS

## When to avoid
- you need a production-ready library or framework to drop into your app rather than demo code
- you work primarily in Swift and want modern Swift examples
- you need actively maintained, up-to-date code for the latest iOS versions
