Here’s an open source project released by the Facebook engineering team called AsyncDisplayKit for creating smooth asynchronous interfaces that works well with Pop or conventional app designs.

Within AsyncDisplayKit you’ll find a number of drop-in UI component replacements for UIView, UIControl, UIImageView, UITextView, and UITableView which are threadsafe and can run in parallel on background threads. The end result is increased performance, and there are other additional conveniences such as direct access to CALayer Properties.

You can find AsyncDisplayKit over on the home page.
