You can build and install docset use Docset scheme in Xcode, appledoc need to be pre-installed. Or your can read the Documentation online.

• Download YYKit source code.
• Select YYKit scheme, and run Archive in Xcode, you will get YYKit.framework.
• Drag the YYKit.framwork to your project and linked the required Frameworks below.
• Add -ObjC to your project's Other Linker Flags.
• Import <YYKit/YYKit.h> as you need.

* UIKit.framework
* QuartzCore.framework
* CoreGraphics.framework
* CoreImage.framework
* CoreText.framework
* ImageIO.framework

This library support iOS 6.0 and later.

I want to use my API as if it was provided by system, so I don't add prefix in these categories. I know this is not good, so if you just need some pieces of code in this project, pick them out and don't import the whole library.
