- (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section {   nslog(@"total count: %d",count);  return [objectarray count] ; }   - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {   static nsstring *cellidentifier = @"cell";       uitableviewcell *cell = [tableview dequeuereusablecellwithidentifier:cellidentifier];         if (cell == nil) {    cell = [[[uitableviewcell alloc] initwithstyle:uitableviewcellstylesubtitle reuseidentifier:cellidentifier] autorelease];    cell.textlabel.numberoflines = 0;   cell.textlabel.font = [uifont fontwithname:@"arial" size:12.0];   cell.detailtextlabel.font = [uifont fontwithname:@"arial" size:10.0];    [cell.textlabel sizetofit];   [cell setaccessorytype:uitableviewcellaccessorydetaildisclosurebutton];       }   // configure cell.   nslog(@"row number %d", indexpath.row);  cell.textlabel.text = [objectarray name];  return cell; }
