JLNRBarController has been tested on iOS 7 and 8. It should be easy get it to work on iOS 6 as well. JLNRBarController uses UICollectionView internally, so using it on iOS 5 could possibly work if you use it with PSTCollectionView.
You can simply copy the files in Classes into your project, but the easiest way is to use CocoaPods.
CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like JLNRGravityImageView in your projects. See the "Getting Started" guide for more information.
