iOS cocos2d实现slider（滑块）控件效果源码
这半年一直在用object-c开发一个ios游戏。使用cocos2d和box2d 。开发游戏变的简单多了。这游戏开发了半年多了。直到最近这个游戏停止了，因为资金问题，老大没法在发更多的工资了。哎，真的非常遗憾，我一个人完成游戏的编辑器开发，脚本开发，游戏代码开发，很不容易，因为我学object-c,coco2d才看了2个星期的书就直接开发了,以前是搞c++的吗。感觉4个人开发游戏真的很累，游戏为了脱颖出更加真实的效果还使用了物理引擎,在老大的同意的情况下，我共享cocos2d自己写的一些大家比较常用的，因为cocos2d有些控件不怎么好用或者没有,反正我觉得是这样的。如slider(滑块),button(按钮),RollNumber(数字滚动),Progress(进度条)....控件一一在我的博客里面公布，可以直接使用.源码打包下载
