Why disclosure indicator don't show?

When app run in simulator Disclosure indicator don't show.Because of this I can not go to Detail

NamesTableViewController.m :

#import "NamesTableViewController.h"

@interface NamesTableViewController ()
@property (nonatomic, copy) NSDictionary *propertyList;
@property (nonatomic, copy) NSArray *letters;
@property (nonatomic, copy)NSMutableArray *filteredNames;
@property (nonatomic, strong)UISearchController *searchController;


@end

@implementation NamesTableViewController

@synthesize propertyList,  letters, filteredNames, searchController;

- (void)viewDidLoad {
    [super viewDidLoad];

    UITableView *tableView = (id)[self.view viewWithTag:1];

    [tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:@"Cell"];

    filteredNames = [[NSMutableArray alloc]init];
    searchController = [[UISearchController alloc]init];

    //bura bax self yigishdir
    self.searchController.searchResultsUpdater = self;

    NSString *path = [[NSBundle mainBundle] pathForResource:@"names" ofType:@"plist"];
    self.propertyList = [NSDictionary dictionaryWithContentsOfFile:path];
    self.letters = [[self.propertyList allKeys] sortedArrayUsingSelector:@selector(compare:)];
}

#import <UIKit/UIKit.h>


@interface NamesTableViewController : UITableViewController <UISearchDisplayDelegate, UISearchBarDelegate>


@property (strong, nonatomic) IBOutlet UISearchBar *searchBar;

@end

How can I accomplish this?Please help me. I am new

try this

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;

    .......
}

Update

 - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// Navigation logic may go here, for example: If your are used in connection 
// use this

   [self performSegueWithIdentifier:@"yourSegueName" sender:self];

 // if you are used connection less in storyboard , use this
 DetailViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"DetailViewController"];
   // Push the view controller.
[self.navigationController pushViewController:vc animated:YES];
