And in the code it also implements the jump

[self performseguewithidentifier:@ "Detailviewbycell" sender:p];

-(void) Prepareforsegue: (Uistoryboardsegue *) Segue sender: (ID) sender{   if ( [Segue.identifier isequaltostring:@ "detailviewbycell"]) {        trdetailviewcontroller* detailvc=[Segue Destinationviewcontroller];        person * p=self.persons[[Self.tableview Indexpathforselectedrow].row];            Detailvc.editperson=p;    }      }
