## What it is
An Objective-C iOS library for building nested multi-page scrolling layouts with hover/suspension effects, similar to Tesla, QQ contacts, Meituan, Taobao, JD, Weibo, and news apps. It supports UIScrollView, UITableView, and UICollectionView child lists with lazy-loaded controllers and a dual-cache mechanism for performance.

## Use cases
- build a profile page with a stretchable header and swipeable tab pages on iOS
- implement QQ contacts-style suspended section header layout
- create a nested scroll view where the header scrolls away and the menu pins to the top
- replicate Taobao or Meituan style multi-page scrolling in an iOS app
- embed multiple UITableView or UICollectionView pages under a shared header
- add pull-down header zoom/stretch effect to a paged iOS screen

## When to choose
- you need a mature, battle-tested nested scroll/pinned-header component for UIKit with multiple layout styles
- your project is Objective-C or mixed Objective-C/Swift on iOS 8+
- you want controller lifecycle preservation and lazy loading of child pages out of the box

## When to avoid
- you are building with SwiftUI or want a Swift-native implementation
- you need active maintenance or recent iOS version support - the last release was 2021
- you need MJRefresh beginRefreshing support with SuspensionTop/SuspensionCenter styles, which is unsupported
