telly/tlyshynavbar

TLYShyNavBar is a component for iOS apps that makes the navigation bar at the top of the screen automatically hide as the user scrolls down and reappear as they scroll up. This behavior is familiar from apps like Facebook, Instagram, and 9gag (which uses this library directly). The goal is to give content more vertical space while the user is reading or browsing, without requiring the developer to write the scrolling logic from scratch. Adding it to a project takes one line of code once the library is installed via CocoaPods or Carthage. You assign your scroll view to a shyNavBarManager property that attaches itself to your view controller, and the component handles the rest automatically. It works with UIScrollView, UITableView (including table headers), and UICollectionView. One limitation the README notes: it should not be used with UITableViewController directly, instead, embed a UITableView inside a plain UIViewController. Beyond the basic hide-and-show behavior, TLYShyNavBar offers several configuration options. You can attach an extension view (such as a toolbar) beneath the navigation bar that slides away first before the bar itself begins to shrink. You can make the extension view or the navigation bar sticky so it stays on screen even when fully scrolled. Resistance settings let you control how far the user must scroll before the bar starts contracting or expanding, and fade behavior is also configurable. The library supports both opaque and translucent navigation bar styles and handles edge cases like in-call status bars. It can be used in Swift projects through a bridging header using the same Objective-C setup instructions. The project is released under the MIT license.
