Xcode 뷰 기반 인터페이스 빌더에서 간단한 UIWindow로 makeKeyAndOrderFront를 사용할 수 있습니까?

Question

NSWindow와 UIWindow의 차이점이 무엇이 아닌가요?

그리고이 makeKeyandOrderFront 함수를 얼마나 정확하게 구현합니까?

여기까지 내가 지금까지 가지고있는 모든 코드가 있습니다.

은 UIWindow 클래스는 방법은 makeKeyAndOrderFront:라고하지 않는다; 그것 은 iOS에서 가장 가까운 것으로 보이는 makeKeyAndVisible라고하는 방법이 있습니다. 그게 당신이 묻는 것이라면, 문서를 검색해 보면 대답했을 것입니다.
