推荐答案

将UISearchBar拖入IB并进行连接它到您的视图控制器。它需要一个委托才能起作用，因此，您可以使您的视图控制器符合UISearchBarDelegate协议，或者可以在数据层中进行搜索。但是最好的方法是使用UISearchDisplayController。委托以任何方式需要访问要搜索的数据，以便可以使用谓词来过滤数据。 这是 Apple的示例之一。

Drag a UISearchBar into IB and connect it to your view controller. It needs a delegate to function so, you could make your view controller conform to the UISearchBarDelegate protocol or you could do the searching in your data layer. But the best way is to use a UISearchDisplayController. Any way the delegate needs access to the data being searched so that it can use a predicate to filter the data. Here's one of Apple's examples of how to do this.
