UIScrollView does not conform to the Copying protocol therefore you cant use the copy method on it. What you can do is to archive and unarchive it and this should give you a deep copy of a view:

id copyOfView = [NSKeyedUnarchiver unarchiveObjectWithData:[NSKeyedArchiver archivedDataWithRootObject:firstScrollView]];
