iphone - iOS6 CALayer freeing/unloading for views in a scrollview that are scrolled non-visible

Question

I'm aware that under iOS6, a UIView's CALayer is automatically unloaded and freed in low memory conditions, instead of the views themselves being unloaded. I love this new feature, so much easier to deal with.

However, just one corner-case i'd love clarification on: If i have a UIScrollView with a lot of child views, under low memory conditions, are the views that are scrolled out of the visible area eligible for layer unloading?

Answer 1

I would assume so, yes.

And it's the bitmap of the CALayer that's actually cleaned up. Check out this blog.
