uisearchdisplaycontroller - searchDisplayController deprecated in iOS 8

Question

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

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;
}

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

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