UITableView semi-sticky tableViewHeader like App Store detail view

Question

I'm looking to have a semi-sticky tableViewHeader just like the iOS7 app store detail view. The detail view is the screen with the Details | Reviews | Related UISegementedControl where you actually download the app. Unfortunately, I don't have enough reputation to post images, but it starts off normally at the top. As you scroll up, it scrolls normally as well. However, once the UISegementedControl hits the top, it sticks. I am going to have multiple sections in the table.

I've gotten this to work correctly visually using auto layout by adding the top view as the tableHeaderView and intercepting the scrollViewDidScroll event:

- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
     if (scrollView.contentOffset.y > 69) //offset from top to uisegmentedcontrol
          self.toolBarHeightToTop.constant = scrollView.contentOffset.y; //toolBarHeightToTop is auto layout constraint from uisegmentedcontrol to top of header
     else
          self.toolBarHeightToTop.constant = 69; //default
}

However, the UISegmentedControl does not detect touch events. Instead, the UITableView delegate method tableView:didSelectRowAtIndexPath: is raised. Any ideas?

Both the header and the segmented control are UITableView Header's and the content below the segmented control belongs in a UITableViewCell

The header (above the UISegmentedControl) is in a UITableView section that doesn't have any rows (but it does have a header).

The UISegmentedControl is the header of a UITableView section that has 1 row - the content that you see and a header - the UISegmentedControl
