这篇文章给大家分享的是有关iOS中如何仿QQ实现侧滑菜单功能的内容。小编觉得挺实用的,因此分享给大家做个参考,一起跟随小编过来看看吧。
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:
