Objective c didSelectRowAtIndexPath不适用于搜索结果

我有表格视图，当我触摸单元格时，detailTextLabel出现。我实现了搜索，但DidSelectRowatineXpath不适用于搜索结果数组。我刚从cellForRowAtIndexPath复制了代码

- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
    {
        NSPredicate *resultPredicate = [NSPredicate predicateWithFormat:@"name contains[c] %@", searchText];
        self.searchResults = [self.cards filteredArrayUsingPredicate:resultPredicate];
    }

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

        return YES;
    }


    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
        UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:@"Card Cell" forIndexPath:indexPath];

        if (tableView == self.searchDisplayController.searchResultsTableView) {
            Card *card = [self.searchResults objectAtIndex:indexPath.row];

            [cell.textLabel setText:[NSString stringWithFormat:@"%@", [card valueForKey:@"name"]]];
            [cell.detailTextLabel setText:[NSString stringWithFormat:@"%@", [card valueForKey:@"otherSide"]]];
            cell.detailTextLabel.hidden = YES;

        } else {
            Card *card = [self.cards objectAtIndex:indexPath.row];

            [cell.textLabel setText:[NSString stringWithFormat:@"%@", [card valueForKey:@"name"]]];
            [cell.detailTextLabel setText:[NSString stringWithFormat:@"%@", [card valueForKey:@"otherSide"]]];
            cell.detailTextLabel.hidden = YES;
        }

        return cell;
    }


    - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
    {

        [self.tableView beginUpdates];

        UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:@"Card Cell" forIndexPath:indexPath];
        if (tableView == self.searchDisplayController.searchResultsTableView) {
            Card *card = [self.searchResults objectAtIndex:indexPath.row];

            [cell.textLabel setText:[NSString stringWithFormat:@"%@", [card valueForKey:@"name"]]];
            [cell.detailTextLabel setText:[NSString stringWithFormat:@"%@", [card valueForKey:@"otherSide"]]];
            cell.detailTextLabel.hidden = NO;
        } else {
            Card *card = [self.cards objectAtIndex:indexPath.row];

            [cell.textLabel setText:[NSString stringWithFormat:@"%@", [card valueForKey:@"name"]]];
            [cell.detailTextLabel setText:[NSString stringWithFormat:@"%@", [card valueForKey:@"otherSide"]]];
            cell.detailTextLabel.hidden = NO;
        }

        [self.tableView endUpdates];

    }

cellForRowAtIndexPath

和

didSelectRowAtIndexPath

之间存在一些显著差异

cellForRowAtIndexPath

创建一个单元格或获取单元格堆栈的现有属性，然后输入属性并在其显示之前返回。在didSelectRowAtIndexPath中，您无法在参数中获得该单元格，因此您必须调用

[tableview cellForRowAtIndexPath]

，而不是

[self.tableview dequeueReusableCellWithIdentifier:@“Card cell”forIndexPath:indexPath]

获取单元格并设置属性

还要确保已设置tableview的委托。

什么是“不工作”？您设置了代理吗？这意味着，当我从self.cards数组中选择项目时，会出现detailTextLabel，但当我从searchResults数组中选择项目时，不会出现这种情况。我刚刚在头文件中设置了代理，那么我应该如何在didSelectRowAtIndexPath中调用[tableview cellForRowAtIndexPath]？对不起，我是一名初级开发人员。
