I am observing changes in self.view.superview where “self" is my view controller, “self.view” is the scroll view containing the clip view and collection view. What is strange is that when I place a breakpoint in the block (from observerForName:object:queue:usingBlock) both collectionView.indexPathsForVisibleItems and collectionView.visibleItems return empty arrays, despite the fact I can see the items in the view. I had also thought to try deleting the items (via deleteItemsAtIndexPaths:) and adding them again, and reloadItemsAtIndexPaths: providing paths for the two items in the view. Nothing is triggering collectionView:itemForRepresentedObjectAtIndexPath: again.
