ios - tableView not found on object of type -

i have class named firstviewcontroller subclass of uiviewcontroller , have uitableview in class. need transition class new uiviewcontroller subclass (using segues) when row pressed.

i have made firstviewcontroller uitableviewdelegate , uitableviewdatasource using code -

@interface firstviewcontroller : uiviewcontroller <uitableviewdatasource, uitableviewdelegate> 

i getting error on line of code -

nsindexpath *path = [self.tableview indexpathforselectedrow]; 

how fix problem since tableview found in uitableviewcontroller , not in uiviewcontroller class ?

edit -

here's code related table view -

- (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section{      return [sarray count]; }  - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath{      static nsstring *cellid = @"cell";     uitableviewcell *cell = [tableview dequeuereusablecellwithidentifier:cellid];      if(cell == nil){         cell = [[uitableviewcell alloc]initwithstyle:uitableviewcellstyledefault reuseidentifier:cellid];     }      nsstring *text = [sarray objectatindex:[indexpath row]];     cell.textlabel.text = text;     return cell; } 

you can declare tableview property:

@property(nonatomic, strong) iboutlet uitableview *tableview;
