在NSMutableArray中搜索

Question

你好我如何可以在这个tableView中搜索？ 我使用NSMutableArray的XML解析。当我想搜索时发生错误。我想对细胞进行详细搜索。

你这个代码搜索：

-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText 
{ 
    NSArray * searchResults = [haberlistesi filteredArrayUsingPredicate: [NSPredicate predicateWithFormat: @"al CONTAINS[c] %@ OR baslik CONTAINS[c] %@", searchedString, searchedString]]; 

    //Use this searchResults array as DataSource for your table view and reload the table view, For instance: 
    haberlistesi = [searchResults mutableCopy]; 

    [self.tableView reloadData]; 
} 

编码快乐.. :)
