问题描述

如何创建隐藏/取消隐藏导航栏，就像 pinterest 和许多其他应用正在做的那样?我知道基本思想是使用 UIScrollView 委托并检测我是向上还是向下滚动并基于此显示导航栏.那么如果导航栏被隐藏，我是否也应该调整导航控制器视图高度?这是如何工作的?

How do I create a hiding/unhiding nav bar like what pinterest and many other apps is doing? I know the basic idea is to use the UIScrollView delegate and detect whether I am scrolling up or down and show the nav bar based on that. So should I also adjust the navcontroller view height if the nav bar is hidden? How does this work?
