gistfile1.matlab

    UINavigationBar *navBar = [[self navigationController] navigationBar];
    //If we want a custom logo:
    UIImage *backgroundImage = [UIImage imageNamed:@"background_im"];
    [navBar setBackgroundImage:backgroundImage forBarMetrics:UIBarMetricsDefault];
    
    self.navigationItem.titleView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"logo_img"]] autorelease];
    
    self.navigationController.navigationBar.barStyle = UIBarStyleBlack;
    self.navigationController.navigationItem.backBarButtonItem.tintColor = [UIColor redColor];
    self.navigationController.navigationBar.tintColor = [UIColor redColor];
    self.navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObject:[UIColor blackColor] forKey:UITextAttributeTextColor];
    [[UIBarButtonItem appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys:
                                                           [UIColor blackColor],UITextAttributeTextColor,
                                                           [UIColor whiteColor],UITextAttributeTextShadowColor,nil]forState:UIControlStateNormal];

    self.navigationItem.title = @"title";
    
    [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];
    [self.navigationController setNavigationBarHidden:NO animated:YES];
