取消按钮未显示在UISearchBar中 [英] Cancel button is not shown in UISearchBar

问题描述

我有 UICollectionView 。点击 UINavigationBar 中的搜索按钮，我添加 UISearchController 的搜索栏作为 UINavigationItem 的标题视图。对于iPhone它运作正常。对于iPad，取消按钮不会显示。单独的搜索栏占据整个宽度。

I have UICollectionView. On clicking search button in UINavigationBar, I am adding the UISearchController's searchbar as titleview for UINavigationItem. For iPhone it is working properly. For iPad the cancel button is not shown. The Searchbar alone takes the entire width.

任何人都可以帮我解决这个问题吗？在此先感谢。

Can anyone help me out on this?. Thanks in advance.

推荐答案

iOS7在添加到导航栏时不显示取消按钮。您可以将搜索栏放在另一个视图中像这样。

iOS7 does not show the cancel button when added to a navigation bar.You can put searchbar in another view like this.

UISearchBar *searchBar = [UISearchBar new];
searchBar.showsCancelButton = YES;
[searchBar sizeToFit];
UIView *viewForSearchBar = [[UIView alloc]initWithFrame:searchBar.bounds];
[viewForSearchBar addSubview:searchBar];
self.navigationItem.titleView = viewForSearchBar;
