Blocks in C and Objective-C are downright magical. They make coding easier and potentially quicker, not to mention faster on the front end with multithreading and Grand Central Dispatch. BlocksKit hopes to facilitate this kind of programming by removing some of the annoying - and, in some cases, impeding - limits on coding with blocks.
BlocksKit is a static library for iOS 3.2 and up. It can technically work on Mac OS X 10.6+ (with Chameleon for the UIKit stuff), but this project does not encompass that target at this time.

<NSKeyValueObserving>) using a block handler
- Associated objects using an Obj-C API. (Not directly block-related.)
- BKMacros, for more quickly typing out the above.

- In any header file, insert
#import "BlocksKit/BlocksKit.h". This is a change from previous version. It is not recommended to insert the import statement in your project prefix, as it will break Xcode 4's Code Sense for the entire project.
Documentation is exhaustive and done using AppleDoc.
An Xcode 4 compatible documentation set is available using this Atom link. Add it to Xcode 4's preferences and it'll download automatically.
You can also view the documentation online at my website.
BlocksKit takes, repurposes, fiddles with, and groups together a variety of block-related code generally found here on GitHub. All of the included code is licensed either under BSD, MIT, or is in the public domain. The project itself is free for use in any and all projects and is licensed under MIT.
