研究方向

The issue asks how to persist the collapsed/expanded state of the navigation bar when navigating back. The library AMScrollingNavbar resets the navbar state on each view appear. A solution would involve storing the navbar state (e.g., a boolean flag) in the view controller or a shared manager, and restoring it in viewWillAppear. Inspect the library's source code, particularly the AMScrollingNavbarManager class, to understand how the navbar scrolls and where to hook in state persistence. Review the issue comments for any maintainer suggestions.
