UISearchBar显示SearchBarInNavigationBar [英] UISearchBar displaysSearchBarInNavigationBar

问题描述

我想复制搜索栏滑入导航栏的Twitter应用程序的功能。

I want to replicate the functionality of the Twitter app where the search bar slides in to the navigation bar.

但是我遇到了问题。如果我不添加

However i have run into a problem. If i don't add

[self.searchDisplayController setDisplaysSearchBarInNavigationBar:YES];

进入viewDidLoad栏不会出现。当我点击它时，我在右侧导航项目中有一个搜索按钮，我调用上面的方法。有什么我可以做的，以确保搜索栏被绘制

into viewDidLoad the bar will not appear. I have a search button in the righthand navigation item when i click it i call the above method. Is there anything i can do to ensure the search bar gets drawn

谢谢

推荐答案

您可以在导航栏上添加搜索栏....

You can add search bar on navigation bar....

viewDidLoad： -

initially in your viewDidLoad:-

mySearchBar.frame = CGRectMake(0.0, -80.0, 320.0, 44.0);
[self.navigationController.navigationBar addSubview:mySearchBar];

mySearchBar.frame = CGRectMake(0.0, 0, 320, 44);

在viewWillDisappear中

in viewWillDisappear

[mySearchBar removeFromSuperview];
