You can find navigation bar with UISegmentedControl in Apple Sample Code: https://developer.apple.com/library/ios/samplecode/NavBar/Introduction/Intro.html

Here is my interpretation of this code (create programmatically):

// File MySegmController.h
@interface MySegmController : UIViewController
@end

// File MySegmController.m
#import "MySegmController.h"

@interface MyNavBarView : UIView
@end

@interface MySegmController ()
{
    UISegmentedControl* _segm;
    UITableView* _table;
}
@end

#define SEGM_WIDTH 250

@implementation MySegmController

- (void)loadView
{
    [super loadView];
    self.view.backgroundColor = [UIColor whiteColor];
    self.title = @"Title";

    float w = self.view.bounds.size.width;

    NSArray* items = [[NSArray alloc] initWithObjects: @"One", @"Two", @"Three", nil];
    _segm = [[UISegmentedControl alloc] initWithItems: items];
    [items release];
    [_segm sizeToFit];
    _segm.frame = CGRectMake((w - SEGM_WIDTH) / 2, 0, SEGM_WIDTH, _segm.bounds.size.height);
    _segm.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin;
    _segm.selectedSegmentIndex = 0;

    MyNavBarView* topView = [[MyNavBarView alloc] initWithFrame: CGRectMake(0, 0, w, _segm.bounds.size.height + 10)];
    topView.backgroundColor = [UIColor whiteColor];
    topView.autoresizingMask = UIViewAutoresizingFlexibleWidth;
    [topView addSubview: _segm];
    [_segm release];

    _table = [[UITableView alloc] initWithFrame: CGRectMake(0, topView.bounds.size.height, w, self.view.bounds.size.height - topView.bounds.size.height) style: UITableViewStylePlain];
    _table.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
    _table.dataSource = self;
    _table.delegate = self;
    [self.view addSubview: _table];
    [_table release];

    // add topView AFTER _table because topView have a shadow
    [self.view addSubview: topView];
    [topView release];
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.navigationController.navigationBar.translucent = NO;
    // pixel_transp.png - 1x1 image with transparent background
    self.navigationController.navigationBar.shadowImage = [UIImage imageNamed: @"pixel_transp"];
    // pixel.png - 1x1 image with white background
    [self.navigationController.navigationBar setBackgroundImage: [UIImage imageNamed: @"pixel"] forBarMetrics: UIBarMetricsDefault];

    UIBarButtonItem* bt = [[UIBarButtonItem alloc] initWithBarButtonSystemItem: UIBarButtonSystemItemCancel target: self action: @selector(onCancel)];
    self.navigationItem.rightBarButtonItem = bt;
    [bt release];
}

- (void)onCancel
{
    [self.presentingViewController dismissViewControllerAnimated: YES completion: NULL];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return 2;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier: @"MyId"];
    if (!cell) cell = [[[UITableViewCell alloc] initWithStyle: UITableViewCellStyleDefault reuseIdentifier: @"MyId"] autorelease];
    cell.textLabel.text = @"text";
    return cell;
}

@end

@implementation MyNavBarView

- (void)willMoveToWindow: (UIWindow *)newWindow
{
    self.layer.shadowOffset = CGSizeMake(0, 1.0f / UIScreen.mainScreen.scale);
    self.layer.shadowRadius = 0;
    self.layer.shadowColor = [UIColor blackColor].CGColor;
    self.layer.shadowOpacity = 0.25f;
}
