在 SWIFTUI 视图中从 photoLibrary UIImagePicker 捕获用户选择

Question

我是 SWIFT UI 的新手，并试图让用户在 SWIFT UI 视图中从本地库中选择一张照片。我被困在实际捕捉用户动作上。

这是我创建选择器的尝试：

final class ChooseImageView: NSObject, UIViewControllerRepresentable, UIImagePickerControllerDelegate, UINavigationControllerDelegate  {
    
    func makeUIViewController(context: UIViewControllerRepresentableContext<ChooseImageView>) -> UIImagePickerController {
        let libraryPicker = UIImagePickerController()
        libraryPicker.sourceType = .photoLibrary
        libraryPicker.delegate = self
        
        return libraryPicker
    }
    
    func updateUIViewController(_ uiViewController: UIImagePickerController,
                                context: UIViewControllerRepresentableContext<ChooseImageView>) {
        
    }
    
    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        
        // I don't see this ever
        print("I got a change")
    }
    
    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        picker.dismiss(animated: true, completion: nil)
    }
}

我正在尝试将其嵌入到如下所示的视图中：

struct PhotoPage: View {
    
    var body: some View {
        VStack(alignment: .center) {
            ChooseImageView()
        }
    }

}

有人知道我怎样才能执行该打印语句吗？

好吧，我运行了你的代码，我可以在控制台中看到打印语句。
