我有 uitableview 和一个带有 searchDisplayController 的搜索栏，我用数据库中的数据填充 tableview 数据源，我使用用户搜索栏进行搜索，一次未过滤 uitableview 数据源，didSelectRowAtIndexPath 工作正常，它转到 detailviewcontroller，但是当我使用搜索时并过滤数据源，然后如果我选择一个单元格，didSelectRowAtIndexPath 方法不会触发。

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    KardexViewController* kardexViewController = [[KardexViewController alloc] initWithStyle:UITableViewStylePlain];

    [self.navigationController pushViewController:kardexViewController animated:YES];
}

这就是我添加 uisearchbar 的方式

- (void)viewDidLoad
{
    [super viewDidLoad];

    dataSource = [[NSMutableArray alloc] init];

    self.navigationItem.title = Title;

    searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];

    searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self];
    searchDisplayController.delegate = self;
    searchDisplayController.searchResultsDataSource = self;

    self.tableView.tableHeaderView = searchBar; 
}

以及我如何过滤数据源

- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
    NSMutableArray* result = [[NSMutableArray alloc] init];

    for (int i = 0; i < [self.allData count]; i++) {
        NSRange range = [[[self.allData objectAtIndex:i] valueForKey:@"Code"] rangeOfString:searchString];

        if(range.length > 0)
            [result addObject:[self.allData objectAtIndex:i]];

        range = [[[self.allData objectAtIndex:i] valueForKey:@"Name"] rangeOfString:searchString];

        if(range.length > 0)
            [result addObject:[self.allData objectAtIndex:i]];
    }

    self.dataSource  = [result copy];
    [result release];
    [self.searchDisplayController.searchResultsTableView reloadData];

    return YES;
}

-(void) searchDisplayControllerDidEndSearch:(UISearchDisplayController *)controller
{
    self.dataSource  = [self.allData copy];
}

所以谢谢提前

经过一番搜索，我发现我应该再设置一件事

searchDisplayController.searchResultsDelegate = self;
