iOS中的导航栏按钮可见性问题

Question

I am having issue with the navigation bar buttons. It looks good(visible) when present the view controller. When I present a another view controller on it it disappears the previous view controller bar button item (But they work when taps but not visible).

I am presenting the new view controller like this

let navVC = UINavigationController(rootViewController: serverPhotosCategoryVC)
            navVC.modalTransitionStyle = presentationStyle
            appDelegateObj.navigationController?.presentViewController(navVC, animated: true, completion: nil)

Please let me know what could be the issue. I have tried many types of codes for that. But they can't help it.

Thanks

If you present from viewController, should present from viewController instead of using navigationController

let navVC = UINavigationController(rootViewController: serverPhotosCategoryVC)
navVC.modalTransitionStyle = presentationStyle
self.presentViewController(navVC, animated: true, completion: nil)
