UIScrollView，背景设置为模糊图像

Question

I have a UIScrollView that shows certain images based on an index. When an image loads, I want to set the background of the UIScrollView to the blurred version of that image. Right now I have a container view that houses the scrollView , and I've been trying to add a blurred subView to the container but it's not working out. If I just add the subview it gets rendered over the scrollView which id obviously no good, and If I add the subView and send it to back then I don't see any blurred effect at all.

Is this the right approach or is there a better way to achieve the effect I'm going for?

Answer 1

As you said "and If I add the subview and send it to back then I don't see any blurred effect at all."

To sort it out, You may try changing the background color of Scrollview to clearColor.
