How to create Navigation bar with back button to the left?

Question

In my app I am trying to navigate from the Second ViewController to the First ViewController using a Navigation Bar Back Button, but while dragging and dropping the navigation bar onto the ViewController in my App's XIB I am just able to get the bar with title.

What am I doing wrong? I am using Xcode 4.6. and .xib files to design the view. Here's What I'm getting now:

Here's what I'm looking for:

Answer 1

add this code in your BUS2AppDelegate.h file

@interface BUS2AppDelegate : UIResponder <UIApplicationDelegate>
{
     UINavigationController *navController;   //you have added this code?
}
@property (strong, nonatomic) UIWindow *window;

@property (strong, nonatomic) ViewController *viewController;
    @end

and in BUS2AppDelegate.m file

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
     self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

        // Override point for customization after application launch.
    self.viewController = [[BUS2ViewController alloc] initWithNibName:@"BUS2ViewController" bundle:nil];

    // View Controller with each Navigational stack support.
    navController = [[UINavigationController alloc]
                     initWithRootViewController:self.viewController];
    self.window.rootViewController = navController;
    [self.window makeKeyAndVisible];

    return YES;
}

add this code in your first view controller

#import "AAlesund.h"

- (IBAction)secodVCBtnClicked:(id)sender {


    AAlesund *aAlesund = [[AAlesund alloc] initWithNibName:@"AAlesund" bundle:nil];

self.navigationItem.title = @"Master";
    [self.navigationController pushViewController:aAlesund  animated:NO];
}

To add title in navigation bar in second view controller add this code

- (void)viewDidLoad
{
    [super viewDidLoad];

    UILabel *nav_title1 = [[UILabel alloc] initWithFrame:CGRectMake(60, 10, 220, 25)];
    nav_title1.font = [UIFont fontWithName:@"Arial-BoldMT" size:18];
    nav_title1.textColor = [UIColor whiteColor];
    nav_title1.adjustsFontSizeToFitWidth = NO;
    nav_title1.textAlignment = UITextAlignmentCenter;
    nav_title1.text = @"Detail";
    nav_title1.backgroundColor = [UIColor clearColor];
    self.navigationItem.titleView = nav_title1;
}

this is the output.
