if (item != nil)
{
[self.contactsarray addObject:item];
[self.tableView reloadData];
}
}

Looks like you've implemented the UISearchDisplayController delegates - but to actually filter the array every time a new character is entered you also need to implement the UISearchBar delegate method textDidChange. Filter your data in that method.
Here's a demo project I've written - hope it helps: https://github.com/versluis/TableSearch2014
