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 framework for OS X Mountain Lion and newer and a static library for iOS 6 and newer. BlocksKit was created by [Zachary Waldowski](https://github.com/zwaldowski) and [Alexsander Akers](https://github.com/a2) and is maintained by Zachary Waldowski. Installation ============ BlocksKit can be added to a project using [CocoaPods](https://github.com/cocoapods/cocoapods). One may also use targets included in the project. ### Library * Download a release of BlocksKit. * Run "Archive" in XCode. * By default the static library will be compiled to `~/Library/Developer/Xcode/DerivedData`. * Move libBlocksKit.a and Headers to your project's folder, preferably a subfolder like "Vendor". * In "Build Phases", Drag libBlocksKit.a into your target's "Link Binary With Libraries" build phase. * In the build settings of your target or project, change "Other Linker Flags" to `-ObjC`. Make sure your app is linked with CoreGraphics, Foundation, MessageUI, and UIKit. * Change (or add) to "Header Search Paths" the relative path to BlocksKit's headers, like `$(SRCROOT)/Vendor/Headers`. * Insert `#import ` in your project's prefix header. ### Framework See the included `Configurations/MacBundleFramework.xcconfig` for more information. Documentation ============= An Xcode-compatible documentation set is available [from CocoaDocs](http://cocoadocs.org/docsets/BlocksKit/). License ======= BlocksKit is maintained under the MIT license. **The project itself is free for use in any and all projects.** You can use BlocksKit in any project, public or private, with or without attribution - though we prefer attribution! It helps us. Unsure about your rights? [Read more.](http://opensource.org/licenses/MIT) Individual credits for included code exist in the header files and documentation.

There are a lot of _TODOs_ in the project, since it's not finished yet. Although the basic functions are OK to use, things like re-order, add or delete pages with animation, etc still need more work. Before I have time to finishe the project, I am not going to give any example to show how to use the project. But as you can see, the project is very similar to UITableView, so if you do understand how to use UITableView, I don't think it's going to be too hard in using the project. ===============
