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).
