How to set up my iOS storyboard to bounce like Instagram Stream?

Question

I am building an app with a stream of social content and am trying to get the behavior of how instagram does it's stream in app. So basically a top header that scrolls off the screen but bounces between that and the content. I can make the top header scroll off the screen and I can make the view not bounce but I want to use Pull to refresh and that ends up going above the "faux" nav bar UIView. I know that a normal Navbar will produce this but this one that scrolls off is a different story.

Currently I have a UITableview that has a UIView above the UITableViewCell and everything works great except the bounce happens above the UIView. I figure I need to get the UIView above the UITableView however in the UITableViewController the storyboard won't allow me to place the UIView above the UITableView.

Any ideas???

Thanks

Well I finally got this all to work so I thought I would post the Answer for everyone.

Basically I set a standard Navigation bar and then on scrollViewDidScroll I get the offset of the scrolling and change the frame based on that. This seems to work perfectly, see below for my scrollViewDidScroll method.

- (void)scrollViewDidScroll:(UIScrollView *)sender {

    //Initializing the views and the new frame sizes.
    UINavigationBar *navbar = self.navigationController.navigationBar;
    UIView *tableView = self.view;

    CGRect navBarFrame = self.navigationController.navigationBar.frame;
    CGRect tableFrame = self.view.frame;

    //changing the origin.y based on the current scroll view.
    //Adding +20 for the Status Bar since the offset is tied into that.
    navBarFrame.origin.y = MIN(0, (sender.contentOffset.y * -1)) +20;
    navbar.frame = navBarFrame;

    tableFrame.origin.y = MIN(0,MAX(-44,(sender.contentOffset.y * -1)));
    tableView.frame = tableFrame;

}

Also you will want to make your TableView 44px taller to compensate for the scrolling otherwise your frame will not be big enough. I just did this in viewWillAppear and made the frame bigger.
