## What it is
An Objective-C library providing a custom UINavigationBar and UINavigationController that smoothly transition navigation bar states (style, tint color, background image/alpha, hidden state, shadow, title attributes) between view controllers. It mimics the polished per-page navigation bar transitions seen in apps like WeChat.

## Use cases
- smoothly switch navigation bar style between view controllers
- hide the navigation bar on some pages without affecting others
- fade navigation bar background alpha as the user scrolls
- show or hide the navigation bar shadow line per screen
- give each view controller its own navigation bar background color or image
- control swipe-back gesture behavior per view controller

## When to choose
- building an iOS app in Objective-C or Swift that needs WeChat-like smooth navigation bar transitions
- you need per-view-controller navigation bar styling with animated transitions during interactive pop gestures
- you want declarative per-page bar configuration without cleanup code

## When to avoid
- starting a new project, since the author states the library is no longer maintained and will be archived
- targeting only modern iOS versions where newer APIs may suffice
- you need a cross-platform or SwiftUI-native solution
