SwiftUI에 UIKit view, viewController 통합
UIKit Project ← SwiftUI View
SwiftUI Project ← UIKit View/ViewController
Adding UIKit views to SwiftUI view hierachies
protocol UIViewRepresentable
A wrapper for a UIKit view that you use to integrate that view into your SwiftUI view hierarchy.
struct UIViewRepresentableContext
Contextual information about the state of the system that you use to create and update your UIKit view.
protocol UIViewControllerRepresentable
A view that represents a UIKit view controller.
struct UIViewControllerRepresentableContext
Contextual information about the state of the system that you use to create and update your UIKit view controller.
UIKit VC를 SwiftUI 프로젝트에 사용할 때
UIKit에서 만든 VC를 SwiftUI에서 만든 프로젝트에서 사용할 경우 아래와 같은 방법으로 하면 손쉽게 사용가능하다.
UIViewControllerRepresentable을 채택하게 만들고func updateUIViewController(_ uiViewController: UIViewControllerType, context: Context) { }func makeUIViewController(context: Context) -> some UIViewController을 구현한다. func getRepresentable() -> some View를 VC에서 호출하면 SwiftUI에서 사용가능하다.
// MARK: - ViewController Representable
extension MainViewController {
private struct ViewControllerRepresentable : UIViewControllerRepresentable {
let mainViewController : MainViewController
func updateUIViewController( _ uiViewController: UIViewControllerType , context: Context ) { }
func makeUIViewController( context: Context ) -> some UIViewController {
mainViewController
}
}
func getRepresentable( ) -> some View {
ViewControllerRepresentable ( mainViewController: self )
}
