tableviewcontroller.m :    @implementation citiesviewcontroller         @synthesize   citiesarray,jsonarray;      #pragma mark -      #pragma mark class methods      -(void)retrievedata     {          nsurl *url = [nsurl urlwithstring:getdataurl];         nsdata *data = [nsdata datawithcontentsofurl:url];          jsonarray = [nsjsonserialization jsonobjectwithdata:data options:kniloptions error:nil];          citiesarray =[[nsmutablearray alloc]init];          (int i= 0; i<jsonarray.count; i++)         {             nsstring *cid = [[jsonarray objectatindex:i] objectforkey:@"id"];             nsstring *cname = [[jsonarray objectatindex:i] objectforkey:@"name"];             nsstring *ccompany = [[jsonarray objectatindex:i] objectforkey:@"company"];             nsstring *cposition = [[jsonarray objectatindex:i] objectforkey:@"position"];             nsstring *cemail = [[jsonarray objectatindex:i] objectforkey:@"email"];              nsstring *cnumber = [[jsonarray objectatindex:i] objectforkey:@"number"];             nsstring *cphoto = [[jsonarray objectatindex:i] objectforkey:@"photo"];              nsurl *urlone = [nsurl urlwithstring:cphoto];        //     nslog(@"%@",urlone);             nsdata *photodata = [nsdata datawithcontentsofurl:urlone];             uiimage *imageone = [[uiimage alloc] initwithdata:photodata];              [citiesarray addobject:[[city alloc]initwithcityname:cname andcitystate:ccompany andcitycountry:cemail andcitypopulation:cposition andcityid:cid andcitynumber:cnumber andcityphoto: (uiimage *) imageone]];          }          [self.tableview reloaddata];      }      - (void)viewdidload {         [super viewdidload];         [self retrievedata];      }      #pragma mark - table view data source      - (nsinteger)numberofsectionsintableview:(uitableview *)tableview {             return 1;         }      - (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section {             return citiesarray.count;      }      - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {           uitableviewcell *cell = [tableview dequeuereusablecellwithidentifier:@"cell" forindexpath:indexpath];          // configure cell...           city *cityob;         cityob=[citiesarray objectatindex:indexpath.row];         cell.textlabel.text=cityob.employeename;           return cell;      } 

everything works fine.cell shows data. problem can not set title header section , section index titles in tableview.and want alphabetic header section because data dynamic static solution problem not suitable. like in tutriole

thanks much.forgive bad english!

- (nsstring *)tableview:(uitableview *)tableview titleforheaderinsection:(nsinteger)section     {        return [citiesarray objectatindex:section];     }
