iOS6 UIStoryboard如何将UICollectionReusableView添加到UICollectionView对象？

Question

I'm running into a silly issue when working with a UICollectionView - I've added a " UICollectionReusableView " by dragging it to within the UICollectionView at the top position. I'm expecting that this is a kind of a header that would be visible (similar to UITableView ). However, when I run the app, I see a blank space of height equal to that of the reusable view over the cells, but nothing else is showing.

What other steps do I need to take to make sure that my reusable view, defined in storyboard shows up when the app is running?
