2. push/pop viewController로 화면 전환

self.navigationController?.pushViewController(rvc, animated: true)

Navigation 투명 ( background 색 변경 )

self.navigationController?.navigationBar.shadowImage = UIImage()
self.navigationController?.navigationBar.isTranslucent = true
self.navigationController?.view.backgroundColor = .clear
