如何从SwiftUI视图呈现UIDocumentInteractionController

如何解决如何从SwiftUI视图呈现UIDocumentInteractionController

我有以下代码，其中包含SwiftUI视图的屏幕截图，并且我想在UIDocumentInteractionController中呈现此屏幕截图。我已经在UIKit ViewController中完成了此操作，我想知道是否有一种方法可以将我必须使用的非工作代码转换为可以呈现UIDocumentInteractionController的代码：

import SwiftUI

struct ContentView: View {
    let documentInteractionController = UIDocumentInteractionController()
    var body: some View {
        vstack {
            SharableView()
            Button(action: {
                let vc = UIHostingController(rootView: SharableView())
                vc.view.frame = CGRect(x: 0,y: 0,width: 400,height: 400)
                if let screenshot = vc.view.makeSnapshot() {
                    if let data = screenshot.pngData() {
                        let filename = getDocumentsDirectory().appendingPathComponent("ScreenShot.png")
                        try? data.write(to: filename)
                        documentInteractionController.uti = "public.image"
                        documentInteractionController.url = filename
                        documentInteractionController.presentOptionsMenu(from: vc.view.bounds,in: vc.view,animated: true)
                    }
                }
            },label: {
                Text("Share")
            })
        }
    }
}

struct SharableView: View {
    var body: some View {
        Text("Hello,world!")
            .padding()
    }
}

func getDocumentsDirectory() -> URL {
    let paths = FileManager.default.urls(for: .documentDirectory,in: .userDomainMask)
    return paths[0]
}

extension UIView {
    func makeSnapshot() -> UIImage? {
        let renderer = UIGraphicsImageRenderer(size: frame.size)
        return renderer.image { _ in drawHierarchy(in: bounds,afterScreenUpdates: true) }
    }
}

这给了我一个合理的错误。但是我不知道如何解决它。传递给documentInteractionController.presentOptionsMenu(...)的正确参数是什么？
