如何从UIViewRepresentable在点击按钮时显示UIViewControllerRepresentable屏幕

struct CustomView: UIViewRepresentable {
    func makeUIView(context: Context) -> UIView {
        // 创建并返回要显示的自定义 UIView
        let customView = UIView()
        // 设置自定义视图的样式和布局
        // ...
        return customView
    }
    
    func updateUIView(_ uiView: UIView, context: Context) {
        // 更新自定义视图的内容和布局
        // ...
    }
}

struct ContentView: View {
    @State private var showCustomView = false
    
    var body: some View {
        VStack {
            Button("显示自定义视图") {
                showCustomView = true
            }
            .sheet(isPresented: $showCustomView) {
                // 在按钮点击时显示 UIViewControllerRepresentable 屏幕
                CustomViewControllerRepresentable()
            }
        }
    }
}

struct CustomViewControllerRepresentable: UIViewControllerRepresentable {
    func makeUIViewController(context: Context) -> UIViewController {
        // 创建并返回要显示的自定义 UIViewController
        let customViewController = UIViewController()
        // 设置自定义视图控制器的样式和布局
        // ...
        return customViewController
    }
    
    func updateUIViewController(_ uiViewController: UIViewController, context: Context) {
        // 更新自定义视图控制器的内容和布局
        // ...
    }
}
