使用MotionKit for your Layout & styling

refer to: https://github.com/motion-kit/motion-kit

内容很多。

The RubyMotion layout and styling gem.   最好的地方就是可以跟其他框架集成。  比如RMQ。

Crossplatform compatibility: iOS, OSX, and planned support for Android
Simple, easy to learn DSL
Crossframework compatibility:
UIKit
AppKit
AutoLayout
Frame geometry
CoreAnimation
NSMenu/NSMenuItem
Easily extendable to support custom, mini-DSLs
Non-polluting
ProMotion/RMQ/SugarCube-compatible (kind of goes hand-in-hand with being non-polluting)
Styles and layouts are "just code" (not hash-based like in Teacup)
