iphone - UITableView scroll problem -

i have created tableview in application 5 sections in it.

sections 1 - 4 contain 1 row each minute , section 5 contains 5 rows.

everything works fine until scroll tableview off screen. in first section , row (cell) have accessoryview set uilabel text in it.

every other cell has disclosure button accessorytype.

when scroll tableview text have in first cell somehow appears in the last cell!?

i have set data adding nsstrings array's , adding them dictionaries nsmutablearray.

and here cell set up:

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {     static nsstring *cellidentifier = @"cell";      uitableviewcell *cell = [tableview dequeuereusablecellwithidentifier:cellidentifier];     if (cell == nil) {         cell = [[[uitableviewcell alloc] initwithstyle:uitableviewcellstyledefault reuseidentifier:cellidentifier] autorelease];     }     // uiswitch *auiswitch = [[[uiswitch alloc]initwithframe:cgrectzero]autorelease];      // configure cell.       nsdictionary *dictionary = [listofsettings objectatindex:indexpath.section];     nsarray *array = [dictionary objectforkey:@"settings"];     nsstring *cellvalue = [array objectatindex:indexpath.row];     cell.textlabel.text = cellvalue;      if([cellvalue isequaltostring:@"status"]){         uilabel *viewlabel = [[uilabel alloc]initwithframe:cgrectmake(0, 0, 100, 20)];         [viewlabel settext:@"connected"];         cell.accessoryview = viewlabel;         [viewlabel release];      }     else{     cell.accessorytype = uitableviewcellaccessorydetaildisclosurebutton;     }     return cell; } 

i know cells deleted/removed when go off screen presume has it? recommended practice dealing cells go off screen , reappear?

just @ quick glance... in else statement, not need set cell.accessorytype, set cell.accessoryview=nil;

the accesoryview still there cell recycled.
