## What it is
An iOS demo application that recreates the WeChat (7.0.0+) app architecture using MVVM, ReactiveCocoa (RAC), and ViewModel-Based Navigation, written entirely in Objective-C. It implements major WeChat features like Moments, Contacts, Search, and the pull-down mini-programs module as a learning reference for iOS MVVM architecture.

## Use cases
- learn MVVM architecture on iOS with ReactiveCocoa
- study how to structure a large iOS app with ViewModel-based navigation
- see a working WeChat clone built in Objective-C
- reference implementation for iOS Moments/Contacts/Search UI
- learn how to organize an iOS project with CocoaPods and Masonry
- understand RAC (ReactiveCocoa) patterns through a real app example

## When to choose
- you want a practical, well-commented Objective-C example of MVVM + RAC on iOS
- you need a reference for building WeChat-like UI features (Moments, Contacts, Search)
- you are an iOS beginner looking to learn ReactiveCocoa through a real project
- you want to study ViewModel-based navigation patterns in a large app

## When to avoid
- you need a production-ready WeChat client or a maintained library
- you prefer Swift or SwiftUI over Objective-C
- you need the latest WeChat UI (some parts still show pre-7.0.0 designs)
- you require active development or frequent updates

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: mobile-framework, state-management, ui-components, routing, form-handling
