There are several resources to do that:

• EGOTableViewPullRefresh - An open source project hosted on GitHub.
• This tutorial from CocoaNetics.
• Included in the three20 library

You can take all needful source codes here: EGOTableViewPullRefresh

You can subclass TTTableViewController and then delegate it to TTTableViewDragRefreshDelegate.

- (id<TTTableViewDelegate>) createDelegate {    
    TTTableViewDragRefreshDelegate *delegate = [[TTTableViewDragRefreshDelegate alloc] initWithController:self];

    return [delegate autorelease];
}
