How to add back ground image to uitableview

Hi
i saw an app made by one of my students and one thing which was missing in his app was a background image behind the table view. as a results when i scrolled the beautiful custom cells white background was visible…. an eye sore…. So here is a tutorial…
1.Take an Image view before the table view.In attribute inspector set its background image.
2.select UITableView
3.Set its background color to  clear color in attribute inspector (Caution : clear color and alpha= 0 are not one and same thing)
4.Good work and God speed you have just added background to your table view…..
A pat on the back !!
