问题描述

我试图在工具栏上的一个.xib文件中放置一个UISearchBar。
i可以将搜索栏拖放到工具栏上，但它显示以下错误。

I am trying to place a UISearchBar on toolbar in an .xib file.i am able to drag and drop the search bar onto the toolbar but it shows the following error.

ControllerName.xib：error：非法配置：UISearchBar嵌入在UIBarButtonItems（只有可用的ub iPad文档）。

请指导我如何将UISearchBar包含在工具栏的xib 。

Please guide me how to include the UISearchBar into the Toolbar in xib.

推荐答案

据我所知，除非你的开发使用 IPAD 在 IPHONE 中的 UIToolBar 中直接添加 UISearchBar ，需要将UISearchBar添加到customView

As far as I know unless you are using IPAD for your development, you can not add UISearchBar directly in UIToolBar in IPHONE , you need to add the UISearchBar to a customView first and then add it to the toolbar programatically

// your searchbar
UISearchBar *searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(xposition, yposition, width, height)];

//create a customview and make its frame equal to your searchbar
UIView *searchBarView = [[UIView alloc] initWithFrame:searchBar.frame];

// add your searchbar to the custom view
[searchBarView addSubview:searchBar];

//finally add it to your bar item of the toolbar

UIBarButtonItem *searchBarItem =
    [[UIBarButtonItem alloc] initWithCustomView:searchBarView];
