iphone - 将 NSFetchedResultsController 与自定义 header 相结合

Question

我想知道是否可以将 NSFetchedResultsController 与自定义 header 结合使用？

这是标准方式:

- (NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index {
    return [myFetchedResultsController sectionForSectionIndexTitle:title atIndex:index];

这是我要设置的内容

- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section 
{
    UIView *headerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 23)] autorelease];

    //set the background
    UIImageView* TopBarHeader = [[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 23)] autorelease];
    [TopBarHeader setImage:[UIImage imageNamed:@"barre_separation_bg.png"]];

    //set the shadow
    [[TopBarHeader layer] setShadowColor:[[UIColor blackColor] CGColor]];
    [[TopBarHeader layer] setShadowOffset:CGSizeMake(1.0f, 3.0f)];
    [[TopBarHeader layer] setShadowOpacity:0.5f];
    [[TopBarHeader layer] setShadowRadius:1.0f];


    [headerView addSubview:TopBarHeader];


    //set the text
    UILabel *textHeader = [[[UILabel alloc] initWithFrame:CGRectMake(11, 0, 320, 20)] autorelease];
    [textHeader setText:[myFetchedResultsController sectionForSectionIndexTitle:title atIndex:index]];
    [textHeader setTextColor:[UIColor colorWithRed:(124/255.0) green:(132/255.0) blue:(137/255.0)  alpha:1]];
    [textHeader setBackgroundColor:[UIColor clearColor]];
    [headerView addSubview:textHeader];

    return headerView;
}

我怎样才能在这条线上工作？

  [textHeader setText:[myFetchedResultsController sectionForSectionIndexTitle:title atIndex:index]];

我找到了方法

[textHeader setText:[[[myFetchedResultsController sections] objectAtIndex:section] name]];
