Post to Friends wall on Facebook failed with Socia

Question

I am trying to POST a invitation to iOS app on my facebook friends wall using Social framework in iOS 6+. But it gives me following error

error =     {
        code = 200;
        message = "(#200) Feed story publishing to other users is disabled for this application";
        type = OAuthException;
    };

I know this is due to Facebook disable this functionality as mentioned on Facebook blog & this stackoverflow question

On stackoverlow's page , it is written that use feed dialog. But I can't see any option to use feed dialog in Social framework.

What is the alternative to POST on friends wall using Social Framewrok in iOS 6 ?

Any kind of help is appreciated. Thanks in advance.
