ios facebook v4 login no working

Have been using facebook v4 and in our most recent build facebook login does not work.  Calling facebook login does not return from the call and no call back is initiated from the call.  If a person is logged in already things appear to work but the login call is not working.  Is this something anyone has experienced?

Replying to my own post to let anyone else know how to fix this if they come across it.  Don’t request anything but basic read only permissions on the first login attempt.
