- (void)tableview:(uitableview *)tableview didselectrowatindexpath:(nsindexpath *)indexpath {     [[tableview cellforrowatindexpath:indexpath] setselected:no];      facebookfriend *friend = [self.fbfriendsfiltered objectatindex:indexpath.row];      // build list invite     if ( [self.fbfriendsinvited containsobject:friend.fid] ) {         [self.fbfriendsinvited removeobject:friend.fid];         nslog(@"fbfriendsinvited:%@",self.fbfriendsinvited);         [[tableview cellforrowatindexpath:indexpath] setaccessorytype:uitableviewcellaccessorynone];     } else {         //if ( [self.fbfriendsinvited count] >= kselectionlimit )           //  return;          [self.fbfriendsinvited addobject:friend.fid];         [[tableview cellforrowatindexpath:indexpath] setaccessorytype:uitableviewcellaccessorycheckmark];         nslog(@"fbfriendsinvited:%@",self.fbfriendsinvited);     } }

you have add conditional check in cellforrowatindexpath: set checkmark cell checked. keep array/set of nsindexpaths of selected cells , check against it.
