How to set rootViewController for navigation view controller and tabbar controller in AppDelegate

i have this problem. When i set rootViewController for TabbarController, it show correctly. But i set another rootViewController for navigation bar, TabbarController will not able to display. Any idea?

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];

    self.window.rootViewController = [[DCTabBarController alloc] init];
    DCTabBarController *tabBar = (DCTabBarController *)self.window.rootViewController;
    [tabBar setSelectedIndex:2];

    Map_ViewController *vc = [[Map_ViewController alloc] init];

    UINavigationController *rootNav = [[UINavigationController alloc] initWithRootViewController:vc];
    [rootNav.navigationBar setBackgroundImage:[UIImage imageNamed:@"navbarBackImage"] forBarMetrics:UIBarMetricsDefault];
    rootNav.navigationBar.tintColor = [UIColor whiteColor];
    [rootNav.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],NSForegroundColorAttributeName, nil]];

    LeftViewController *leftVC = [[LeftViewController alloc] init];

    RightViewController *rightVC = [[RightViewController alloc] init];

    XLSlideMenu *slideMenu = [[XLSlideMenu alloc] initWithRootViewController:rootNav];

    slideMenu.leftViewController = leftVC;
    slideMenu.rightViewController = rightVC;
    self.window.rootViewController = slideMenu;

    [self.window makeKeyAndVisible];

    return YES;
}

After applied Adeel solution, here is the output.But items in tabbar will not display accordingly. enter image description here

One important thing to mention here is that an application's window can have only one rootViewController (of course). Like I said in my comment as well, you probably want to do something like this.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];

    Map_ViewController *vc = [[Map_ViewController alloc] init];

    UINavigationController *rootNav = [[UINavigationController alloc] initWithRootViewController:vc];
    [rootNav.navigationBar setBackgroundImage:[UIImage imageNamed:@"navbarBackImage"] forBarMetrics:UIBarMetricsDefault];
    rootNav.navigationBar.tintColor = [UIColor whiteColor];
    [rootNav.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],NSForegroundColorAttributeName, nil]];

    DCTabBarController *tabBar = [[DCTabBarController alloc] init];
    [tabBar setViewControllers:@[rootNav]];
    self.window.rootViewController = tabBar;

    LeftViewController *leftVC = [[LeftViewController alloc] init];

    RightViewController *rightVC = [[RightViewController alloc] init];

    XLSlideMenu *slideMenu = [[XLSlideMenu alloc] initWithRootViewController:tabBar];

    slideMenu.leftViewController = leftVC;
    slideMenu.rightViewController = rightVC;
    self.window.rootViewController = slideMenu;

    [self.window makeKeyAndVisible];

    return YES;
}
