如何创建pinterest样式隐藏/取消隐藏导航/标签栏？ [英] how to create pinterest style hiding/unhiding nav/tab bar?

问题描述

如何创建一个隐藏/取消隐藏的导航栏，就像pinterest和许多其他应用程序正在做的那样？我知道基本的想法是使用UIScrollView委托并检测我是否向上或向下滚动并显示基于该导航栏的导航栏。如果导航栏被隐藏，我还应该调整导航控制器视图高度吗？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?
