objective c - iOS tableview cell handling -

i have code, "linearedtoday" uiimageview:

- (void)viewdidload {  [super viewdidload];  linearedtoday = [uiimage imagenamed:@"line4.png"];}    - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {   static nsstring *myidentifier = @"myidentifier"; myidentifier = @"tblcellview";  tableviewcell *cell = (tableviewcell*)[tableview dequeuereusablecellwithidentifier:myidentifier]; if(cell == nil) {     [[nsbundle mainbundle] loadnibnamed:@"tableviewcell" owner:self options:nil];     cell = tblcell; }  cell.selectionstyle = uitableviewcellselectionstylenone;  [[lineday objectatindex:currenttodaylinered -1] setimage:linearedtoday];   return cell;    - (ibaction) change{      linearedtoday = [uiimage imagenamed:@"linea.png"];     [lineday setimage:linearedtoday];     [mytableview reloaddata]; } 

it uitableview 15 custom uitableviewcell , want change image @ uiimageview, imageview "lineday", lineday present in cells, , want change image @ cells, ibaction "change" change uiimageview in last cell , not @ all....why?

yes change image in last cell because has reference of last cell, if want when creating cell in cellforrowatindexpath check bool , set image according bool. in ibaction change bool value , call reloaddata on table view reload it. -

    - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath      {         static nsstring *cellidentifier                 = @"test";          uitableviewcell *cellview = [tableview dequeuereusablecellwithidentifier:cellidentifier];          if (cellview == nil)          {             cellview = [[[uitableviewcell alloc] initwithstyle:uitableviewcellstylesubtitle reuseidentifier:cellidentifier] autorelease];              uiimageview *bgimgview = [[uiimageview alloc] initwithframe:cgrectmake(0.0f, 0.0f, 320.0f, 85.0f)];             [bgimgview settag:1];             [bgimgview setbackgroundcolor:[uicolor clearcolor]];             [cellview.contentview addsubview:bgimgview];             [bgimgview release];         }          uiimageview *imgview = (uiimageview*)[cellview viewwithtag:1];          if (buttonpressed)          {             [imgview setimage:[uiimage imagenamed:@"listing_bg"]];         }         else          {             [imgview setimage:[uiimage imagenamed:@"featured_listing_bg"]];         }         return cellview;     }   - (ibaction) change{     buttonpressed = !buttonpressed;     [mytableview reloaddata]; }
