Facebook’s Paper team has come out with another great library: AsyncDisplayKit. This library enables super-responsive user interfaces by letting you perform image decoding, layout and rendering operations on background threads, so they don’t block user interaction. Learn about it in this AsyncDisplayKit tutorial.
For example, you can use AsyncDisplayKit to build silky-smooth, 60-frame-per-second scrolling experiences for very complex interfaces, where normal UIKit optimizations wouldn’t be enough to overcome performance challenges.
In this tutorial, you’ll take a starter project that has some major
UICollectionView scrolling issues and use AsyncDisplayKit to drastically improve its performance. Along the way, you’ll learn how to use AsyncDisplayKit in your existing projects.
