A generic stretchy header implementation for UITableView and UICollectionView in iOS apps.
GSKStretchyHeaderView is an open‑source iOS library that provides a generic stretchy header implementation for UITableView and UICollectionView. It replicates the dynamic header behavior seen in popular apps like Twitter and Airbnb, allowing headers to expand and contract smoothly as users scroll. The library solves the problem of implementing this UI pattern without requiring major changes to existing view controllers or data sources.
iOS developers building apps with UITableView or UICollectionView who want to add polished, interactive stretchy headers. It’s especially useful for those aiming to mimic the header styles of apps like Twitter, Spotify, or Airbnb.
Developers choose GSKStretchyHeaderView because it’s lightweight, non‑invasive, and highly configurable. Unlike custom solutions, it works out‑of‑the‑box with both table and collection views, supports multiple layout methods, and doesn’t force subclassing or layout overhauls.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Works out-of-the-box with both UITableView and UICollectionView, eliminating the need for separate implementations for different scroll view types.
Can be added to existing view controllers without interfering with delegates or data sources, making it easy to retrofit into legacy codebases.
Supports frame-based layout, Auto Layout, and Interface Builder .xib files, accommodating various development styles and project setups.
Offers both immediate and top-reached expansion modes, allowing developers to fine-tune header behavior based on app design requirements.
Lacks built-in handling for iOS 11+ safe areas, requiring developers to manually set contentInsetAdjustmentBehavior to .never and work around iPhone X compatibility issues.
Requires creating a subclass or configuring a .xib file even for basic implementations, which can be more complex than expected for straightforward stretchy headers.
The README acknowledges the need for a major refactor for full iOS 11+ support, indicating future breaking changes or delayed updates that could impact long-term projects.
