如何从 NavigationController 中的 SwiftUI 视图推送到 UIViewController

Question

我有一个 SwiftUI View 从 UINavigationController 中的场景委托实例化我想从 SwiftUI View

推送到另一个 UIViewController

我的场景委托展示了我的 View 是如何实例化的：

    let vc = UIHostingController(rootView:SwiftUIView())
    let navigationControll = UINavigationController(rootViewController: vc)
    self.window?.rootViewController = navigationControll
    // Present window to screen
    self.window?.makeKeyAndVisible()

我怎样才能做到这一点？

您必须将 UIViewController 包装在 SwiftUI View 中，然后导航到那个。

例如

struct MyMasterViewController: UIViewControllerRepresentable {
    func makeUIViewController(context: Context) -> MasterViewController {
        var sb = UIStoryboard(name: "Main", bundle: nil)
        var vc = sb.instantiateViewController(identifier: "MasterViewController") as! MasterViewController
        return vc
    }
    
    func updateUIViewController(_ uiViewController: MasterViewController, context: Context) {
    }
    
    typealias UIViewControllerType = MasterViewController
}

并在 NavigationLink 中像这样从 SwiftUI View

中简单地调用它

struct SwiftUIView: View {
    var body: some View {
        NavigationLink(destination: MyMasterViewController()) {
                           Text("Show Detail View")
        }.navigationBarTitle("Navigation")
    }
}

struct SwiftUIView_Previews: PreviewProvider {
    static var previews: some View {
        SwiftUIView()
    }.   
}
