使用带有UISearchBar的prepareForSegue传递indexPath.row时遇到问题

Question

我有一个时代的狄更斯让整个Core Data,Storyboard,UISearchBar三人组合在一起工作.最后用Core Data成功构建了表,用搜索文本缩小了项目,并修改了prepareForSegue,还有一个打嗝......

当我点击表格中的任何项目进入详细视图时,未经过滤的表格中的一切都很好.调用PrepareForSegue并完美显示细节.

当我搜索时,我的表被过滤了(我现在要过滤数组选项而不是第二个NSFetchedResultsController,但不是因为没有尝试!).

当我单击筛选列表中的某个项目时,将调用prepareForSegue并按下详细信息视图,但是,它始终从列表中的第一个项目中提取详细信息!

例如,如果我搜索"c"并且列表缩小为"查理"和"Cookie",当我选择"查理"时,我会看到"查理"的详细视图.当我选择"Cookie"时,不幸的是,我也看到了"查理"的详细视图

我假设prepareForSegue代码是问题(可能不正确？).这是代码:

    SampleTVC *sampleDetailTVC = segue.destinationViewController;
    sampleDetailTVC.delegate = self;

    // Store selected Role in selectedRole property
    NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
  //  self.selectedRole = [self.fetchedResultsController objectAtIndexPath:indexPath];
    if (savedSearchTerm){
        self.selectedRole = [self.searchResults objectAtIndex:indexPath.row];
    } else {
        self.selectedRole = [self.fetchedResultsController objectAtIndexPath:indexPath];
    }
    NSLog(@"Passing selected role (%@) to SampleTVC", self.selectedRole.name);
    sampleDetailTVC.role = self.selectedRole;

任何帮助,将不胜感激!

感谢Phillip Mills,答案是:

只需添加:

    indexPath = [self.searchDisplayController.searchResultsTableView indexPathForSelectedRow];

完整样本:

    SampleTVC *sampleDetailTVC = segue.destinationViewController;
    sampleDetailTVC.delegate = self;
     // Store selected Role in selectedRole property
    NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
    //  self.selectedRole = [self.fetchedResultsController objectAtIndexPath:indexPath];
    if (savedSearchTerm){
         indexPath = [self.searchDisplayController.searchResultsTableView indexPathForSelectedRow];
    self.selectedRole = [self.searchResults objectAtIndex:indexPath.row];
    } else {
        self.selectedRole = [self.fetchedResultsController objectAtIndexPath:indexPath];
     }
    NSLog(@"Passing selected role (%@) to SampleTVC", self.selectedRole.name);
    sampleDetailTVC.role = self.selectedRole;
