You could do it like described here: Apply blur to UIView

But blurring is computationally intensive, and scrolling performance will most likely be bad.

Make the orange view over the tableview, then set it's opacity.

I don't need to change opacity orange area. I need to blur area under orange view. – Sveta Oct 19 '12 at 11:17
