it how looks in code. i've updated code actual. open graph object id fql first , make comment action. if change post got comments id ok. if post comment got error:

printing description of error: error domain=com.facebook.sdk code=5 "the operation couldn’t completed. (com.facebook.sdk error 5.)" userinfo=0x1d16a590 {com.facebook.sdk:httpstatuscode=500, com.facebook.sdk:parsedjsonresponsekey={     body =     {         error =         {             code = 1;             message = "an unknown error has occurred.";             type = oauthexception;         };     };     code = 500; }   permissions:(     "video_upload",     "share_item",     "publish_stream",     installed,     "status_update",     email,     "create_note",     "photo_upload",     "publish_actions" )
