防止UISearchDisplayController隐藏导航栏 [英] Prevent a UISearchDisplayController from hiding the navigation bar

问题描述

每当用户开始编辑 UISearchDisplayController 的搜索栏时，搜索控制器就会变为活动状态，并在显示搜索表视图时隐藏视图的导航栏。是否可以阻止 UISearchDisplayController 隐藏导航栏而不重新实现它？

Whenever a user begins editing a UISearchDisplayController's search bar, the search controller becomes active and hides the view's navigation bar while presenting the search table view. Is it possible to prevent a UISearchDisplayController from hiding the navigation bar without reimplementing it?

推荐答案

iOS 8引入的新 UISearchController 类有一个属性 hidesNavigationBarDuringPresentation 如果你设置为false想要保持导航栏可见（默认情况下它仍然会被隐藏）。

The new UISearchController class introduced with iOS 8 has a property hidesNavigationBarDuringPresentation which you can set to false if you want to keep the navigation bar visible (by default it will still be hidden).
