如何在iOS 7中实现搜索栏.搜索工作正常，但加载的结果内容与搜索结果不对应

Question

如何选择表视图的搜索结果而不是加载普通的表视图内容

在我的 iOS 项目中使用 UISearchBar .搜索对我来说效果很好，但在选择搜索结果行时，确实选择了加载原始项目的行方法，而不是搜索结果行。我应该使用什么方法来加载结果行及其相应的详细信息页面。

谢谢

法典：

- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString {    // Tells the table data source to reload when text changes
     [self filterContentForSearchText:searchString scope:
     [[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:      
     [self.searchDisplayController.searchBar selectedScopeButtonIndex]]];    
     // Return YES to cause the search result table view to be reloaded.
     return YES;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
     [self performSegueWithIdentifier:@"SubCategory" sender:self];
}      
#pragma mark Content Filtering
- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope {
    // Update the filtered array based on the search text and scope.
    // Remove all objects from the filtered search array
    //[self.filteredArray removeAllObjects];
    // Filter the array using NSPredicate
    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF contains[c] %@",searchText];
    filteredArray=[categoryNameArray filteredArrayUsingPredicate:predicate];     
}        
#pragma mark - UISearchDisplayController Delegate Methods
- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString {
    // Tells the table data source to reload when text changes
    [self filterContentForSearchText:searchString scope:
    [[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:      
    [self.searchDisplayController.searchBar selectedScopeButtonIndex]]];
    // Return YES to cause the search result table view to be reloaded.
    return YES;
}    
 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    NSUserDefaults *usr=[NSUserDefaults standardUserDefaults];
    NSString*fontc=[usr stringForKey:@"fontchange"];
    float fontSize=[fontc floatValue];
    newfont= [UIFont fontWithName:@"Helvetica" size:fontSize];
    static NSString *simpleTableIdentifier = @"SimpleTableCell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
    }

    if (tableView==self.searchDisplayController.searchResultsTableView)
    {
       cell.textLabel.text=[filteredArray objectAtIndex:indexPath.row];
    } else {
       cell.textLabel.text=[categoryNameArray objectAtIndex:indexPath.row];
    }
    cell.textLabel.font=newfont;
    UIImage *img;
    img = [UIImage imageNamed:@"icon_generic.png"];
    cell.accessoryType=UITableViewCellAccessoryDisclosureIndicator;
    cell.imageView.image=img;
    return cell;
}
