哈哈，我是一个不会用markdown的人，之前的一个demo，用markdown灰常简单的写了这篇文章， 这算文章么，哈哈，显然有点不像啊，有时间还得学学markdown啊， 这么简单的东西不会实在过不去，等我整理好github,以后这种东西我就上传到github上吧， 图灵社区（貌似有markdown语法详解）和github以及这里简书都支持markdown语法
########有点跑题，其实整篇都在跑题，大家喜欢这个引导页的，看代码吧。
在这里介绍两个引导页

#######这个是直接用UIPageViewController系统的，是不是帮帮哒的， iOS6都支持哦
大家喜欢就收藏文章吧，真的棒棒哒
