An Objective-C iOS library for building condensing, flexible-height header bars like those in Facebook, Square Cash, and Safari. Subview appearance and scroll-linked behaviors are defined modularly via a progress property and behavior definer classes.
Use cases
- create a shrinking header bar while scrolling a table view
- emulate the Facebook app's collapsing header behavior
- hide chrome to make room for content as the user scrolls
- build a Safari-style condensing navigation bar
- animate subview frames, transforms, and alpha based on bar height
When to choose
- you're building an iOS app in Objective-C or Swift and want Facebook/Safari-style collapsing headers
- you need fully customizable, modular scroll-linked header behaviors
- you want a mature MIT-licensed UIKit component installable via CocoaPods
When to avoid
- you're targeting SwiftUI-first architectures and want native solutions
- you need Android or cross-platform support
- you need a library with frequent recent updates and active maintenance
