To remove bottom border from UINavigationBar you can use below method in app delegate:

- (void) removeBottomBarFromNav:(UINavigationBar *) navBar {
for (id subView in [navBar subviews]) {
    for (id subViewInner in [subView subviews])
    {
        if ([NSStringFromClass([subView class]) isEqualToString:@"_UINavigationBarBackground"])
        {
            if ([subViewInner isKindOfClass:[UIImageView class]]) {
                [subViewInner removeFromSuperview];
                break;
            }
        }
    }
}
}

You can use this method as mention below:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    home * ObjLoginPage = [[home alloc] initWithNibName:@"home" bundle:nil];
    self.navigationController = [[UINavigationController alloc] initWithRootViewController:ObjLoginPage];

    [self removeBottomBarFromNav:self.navigationController.navigationBar];

    self.window.rootViewController = self.navigationController;
        [self.window makeKeyAndVisible];
        return YES;
}
