UISearchBar代替UINavigationController UINavigationBar [英] UISearchBar in place of UINavigationController UINavigationBar

问题描述

我有一个 UITableViewController 与 UISearchDisplayController （和 UISearchBar ），它包含在 UINavigationController 中作为根元素。是否可以配置它，使 UISearchBar 出现 UINavigationBar ？我不认为隐藏导航栏将工作，下一个屏幕（推送）要求它是可见的（这将创建一个奇怪的动画毛刺）。

I have a UITableViewController with a UISearchDisplayController (and UISearchBar) that is contained in a UINavigationController as the root element. Is it possible to configure it so the UISearchBar appears in place of the UINavigationBar? I don't think hiding the navigation bar will work, a the next screen (pushed on) requires it to be visible (and this will create a strange animation glitch).

我基本上打算像 App Store 搜索标签。

I'm basically going for a screen like the App Store search tab.

我已上传了其现在的样子截图：

I've uploaded a sample screenshots of how it looks now:

推荐答案

将自己分配为UINavigationController的委托并实现 - （void）navigationController： （UINavigationController *）navigationController willShowViewController：（UIViewController *）viewController animated：（BOOL）animated 。

Assign yourself as the delegate of the UINavigationController and implement - (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated.

然后使用传入的navigationController隐藏导航栏。
[navigationController setNavigationBarHidden：YES animated：animated]

Then use the passed in navigationController to hide the navigation bar. [navigationController setNavigationBarHidden:YES animated:animated]

来想一想，最好将动画值传递给 -setNavigationBarHidden：animated：。代码已更新。
