iOS 7 UISearchDisplayController not cleaning backg

问题:

I'm upgrading my Apps to iOS 7. Actually I have a big issue with UISearchDisplayController.

If i display it into a PopUp until I don't start a Search it works fine, but when I insert something into the SearchBar the search works fine, but I see the search result overlapped to the old contents.

In iOS 6 it all works fine. Here is a link to an example project which shows the problem. Example project

Attached to this post there are two images.

Thank you for your help.

Seems like the cell's background color is clear color, and so is the table view's. You can either implement the search display controller's delegate method searchDisplayController:didLoadSearchResultsTableView: and set the background color to what you need (but not [UIColor clearColor]). Or change your cells' background color to be an opaque color.
