Search in a NSMutableArray - objective-c

Question

Hello how I can search in tableView with this?
I use XML parse for NSMutableArray. Gives error when I want to search. I want to make a detailed search for the cell.

You this code for searching :
-(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];
}
Happy Coding..:)
