You should store all the search items in an array. When the user start searching(use UISearchBar), code in the following delegate

- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText
{
     //Find all the value matches your searchText
     //Display them in a tableView.
}
