searchDisplayController在iOS 8中已弃用 [英] searchDisplayController deprecated in iOS 8

问题描述

如何更正以下内容，以免出现警告？
我缺少什么？

How do you correct the following so no warnings appear? What am I missing?

将 searchResultsController 更正为 searchController 它给我一个错误找不到对象

When correcting the searchResultsController to searchController it gives me an error "object not found"

if (tableView == self.searchDisplayController.searchResultsTableView) {
        cell.textLabel.text = [searchResults objectAtIndex:indexPath.row];
    } else {
        cell.textLabel.text = [_content objectAtIndex:indexPath.row];
    }

    return cell;
}

-(BOOL)searchDisplayController:(UISearchDisplayController *)controller
  shouldReloadTableForSearchString:(NSString *)searchString
{
    [self filterContentForSearchText:searchString
                               scope:[[self.searchDisplayController.searchBar scopeButtonTitles]
                       objectAtIndex:[self.searchDisplayController.searchBar selectedScopeButtonIndex]]];
    return YES;
}

推荐答案

UISearchController 类替换了 UISearchDisplayController
类，用于管理与搜索相关的接口的显示。

The UISearchController class replaces the UISearchDisplayController class for managing the display of search-related interfaces.

所以，正如rmaddy所说，如果你想摆脱已弃用的警告，请停止使用已弃用的类。改为使用 UISearchController ：

So, as rmaddy said, if you want to get rid of the deprecated warnings, stop using the deprecated classes. Use UISearchController instead:
