使用cocostudio能够装载编辑好的UI，可是过于复杂。特别是在加截UI后，发现触屏事件有些问题。

假设直接使用程序写死载入UI又过于麻烦。花点时间，添加了一个基于ini的UI配置类，眼下仅仅实现了CCSprite和plist的载入。其他的能够后面慢慢加

配置文件

#支持UTF-8格式

[ gk_label.png ]

type = CCSprite

image = gk_label.png

tag = 1

x = 18

y = 914

zOrder = 1

[ mb_label.png ]

type = CCSprite

image = :mb_label.png ·#冒号开头表示从CCSpriteFrameCache载入图片

tag = 1

x = 348

y = 916

zOrder = 1

[ score_label.png ]

type = CCSprite

image = score_label.png

tag = 1

x = 258

y = 855

zOrder = 1

[ game_star.plist ]

#批量装载

type = plist

filename = game_star.plist
