Vapor and moisture barrier for "above ground" basement
You can put a vapor/moisture barrier up over rigid foam.  A lot of new construction in the far north has this as a default.  The idea is that you frame right outside of that.  In that framing you are allotting a cavity to which moisture can move and evaporate.  

Now if you are putting rockwool or other types of insulation in your framing then no you do not use a moisture barrier.  This would in essence trap water which will condensate on the plastic and promote mold growth on drywall.  I am not that smart this is just doing a lot of basements and reading the Building Science reports that are out there for the past 5-6 years.
