Closures

Closures is an iOS Framework that adds closure handlers to many of the popular UIKit and Foundation classes. Although this framework is a substitute for some Cocoa Touch design patterns, such as Delegation & Data Sources and Target-Action, the authors make no claim regarding which is a better way to accomplish the same type of task. Most of the time it is a matter of style, preference, or convenience that will determine if any of these closure extensions are beneficial.

Whether you’re a functional purist, dislike a particular API, or simply just want to organize your code a little bit, you might enjoy using this library.
