uitabbarcontroller做qq侧滑菜单效果：

首先要了解uitabbarcontroller的层级结构：

uitabbarcontroller加载的其它uiviewcontroller的view都是被添加在uitransitionview上（这是一个私有api），uitransitionview在self.view的0层，uitabbar在的第一层。

所以我的思路是这样的：

uitransitionview与uitabbar转移到一个新的view1上去，作为滑动的部分；

在view1与self.view之间再添加一个view2，作为菜单的容器；

给view1添加相应的手势响应；

代码：
