在SwiftUI中，使用swiftUI定位用户图片，就像在IOS设置中一样

import SwiftUI

struct ContentView: View {
    @State private var image: Image?

    var body: some View {
        VStack {
            if image != nil {
                image!
                    .resizable()
                    .aspectRatio(contentMode: .fit)
            } else {
                Text("选择图片")
            }

            Button(action: {
                let picker = UIImagePickerController()
                picker.delegate = context.coordinator
                picker.sourceType = .photoLibrary
                UIApplication.shared.windows.first?.rootViewController?.present(picker, animated: true, completion: nil)
            }) {
                Text("选择图片")
            }
        }
        .onAppear {
            requestPhotoLibraryAccess()
        }
    }

    private func requestPhotoLibraryAccess() {
        PHPhotoLibrary.requestAuthorization { status in
            if status == .authorized {
                print("访问相册授权成功")
            } else {
                print("访问相册授权失败")
            }
        }
    }

    private func loadImage(_ image: UIImage) {
        self.image = Image(uiImage: image)
    }

    private func makeCoordinator() -> Coordinator {
        Coordinator(self)
    }

    class Coordinator: NSObject, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
        let parent: ContentView

        init(_ parent: ContentView) {
            self.parent = parent
        }

        func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
            if let uiImage = info[.originalImage] as? UIImage {
                parent.loadImage(uiImage)
            }

            picker.dismiss(animated: true, completion: nil)
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
