ios - Keep expanded UITableViewCell fixed on top -

i have implemented skstableview , used command:

[tableview scrolltorowatindexpath:indexpath atscrollposition:uitableviewscrollpositiontop animated:yes]; 

when press cell expandable, , goes on top. i'd when scroll expanded cell went top stay fixed there until it's closed. can that?

in uitableview have uiscrollview methods. can this:

-(void)scrollviewdidscroll:(uiscrollview *)scrollview {      uitableviewcell *cell =[self.mytableview cellforrowatindexpath:[nsindexpath indexpathforrow:0 insection:0]];     cgrect cellframe = [cell convertrect:cell.frame toview:self.view];      if (self.issticktotop) {         self.cell.frame = cgrectmake(0, 0, self.cellframe.width, cellframe.size.height);     }      else {         self.cell.frame = cgrectmake(0, scrollview.contentoffset.y, self.cellframe.width, cellframe.size.height);     }         } 

the issticktotop your maintenance boolvariable indicate if cell stick top or not. don't u don't know ;)
