How to ensure Search bar sticks to the top in iPhone SDK?

I have a table view along with search bar.

How can this be achieved?

I suggest you to Keep both of them separated.

You have to return your search bar in the table's delegate callback

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section

Note: don't forget to implement tableView:heightForHeaderInSection:
