Count;        i++) {Saledgoods *saledgoods = [Saledgoodsarray objectatindex:i]; Scpersonobject * Personobject = [personobjectdics objectforkey:[saledgoods Seatno];if(!personobject)            {personobject = [[Scpersonobject alloc] init];            [[Personobject Purchasedgoodsarr] addobject:saledgoods];        [Personobjectdics setobject:personobject forkey:[saledgoods Seatno]; }Else{[[Personobject Purchasedgoodsarr] addobject:saledgoods]; }    } for(Scpersonobject * Personobject in [personobjectdics allvalues]) {if([Personobject Iskindofclass:[scpersonobject class]])        {[DataArray addobject:personobject]; }    }
