No, I'm not sure :-) I've never worried about that option before, and don't know why it would be different from one approach to the other.
Why do I need it for the block approach and not for the other?
The docs for UIViewAnimationOptionAllowUserInteraction suggest it's only necessary for views that are animating that require user interaction; that is not the case for me. The animating view does not have any user interaction. It's all the other views in my app that fail to respond.
