抽屉效果IOS---仿网易客户端的---初步完成封装---简单易用---IOS

这几天闲着没事,看了几个抽屉效果,总觉得大都写的有些复杂,便自己封装了一个.主要为了自己项目服务,主要按照网易客户端的样式封装,未提供更改中间视图frame的接口,有兴趣的话可以自己试着添加一个frame接口即可. (在ARC开启的情况下封装的)

核心功能:点击左抽屉中的cell,关闭抽屉,可以推出新的中间控制器,或者原本存在的控制器.

抽屉开启的情况下,点击中间视图,收回抽屉.

注意事项:中间视图必须是navigationcontroller,并自己在中间控制器类中重写item的左右button.

必须引入我的类目.最好放进pch文件中,

这是初始版本,肯定还有不尽完善的地方,不喜勿喷.动画等功能还未加入,主要完成抽屉的核心功能.
