UITabBarController做QQ側(cè)滑菜單效果：
首先要了解UITabBarController的層級結(jié)構(gòu)：
UITabBarController加載的其它UIViewController的View都是被添加在UITransitionView上（這是一個私有API）菠赚，UITransitionView在self.view的0層何恶，UITabBar在的第一層茬贵。
所以我的思路是這樣的：
UITransitionView與UITabBar轉(zhuǎn)移到一個新的View1上去，作為滑動的部分渤弛；
在View1與self.view之間再添加一個View2，作為菜單的容器；
給View1添加相應(yīng)的手勢響應(yīng)圃伶；
代碼：
