    self.itemsContainerDefaults = [self.itemsContainer copy]; // breaks here

I'm trying to copy itemsContainer to itemsContainerDefaults but I'm getting the error in the log. Why isn't this working?

In order to call -copy on an object, it must conform to NSCopying. UIScrollView does not.

I think what you want to achieve has a better approach. But I'm not certain what you want to achieve. You want to make a visual copy of the scrollview? Why not just make a new scrollview that uses the same datasource as the first scrollview?
