root view controller:

처음시작하는 화면을 root view controller라고함★

 

Action Segue vs Manual Segue

네이게이션바Navigation Controller를 추가하면 바뀌는 내용

 

Navigation Controller에 storyboard entry point가 생김

Navigation Controller의 navigation stack 가장 하단의 view controller를 root view controller라 하고 View Controller와 segue가 연결되어 있음 

Navigation Controller에 연결된 View Controller에 Navigation Item 생김

 

func prepare(for segue: UIStoryboardSegue, sender: Any?)★

 

destination의 자료형은 UIViewController

 

 

다운캐스트를 통해 자식 프로퍼티에 접근가능해짐

 

 

webview

 

mvc디자인패턴으로 변경
