struct VideoPicker: UIViewControllerRepresentable { @Environment(.presentationMode) private var presentationMode let sourceType: UIImagePickerController.SourceType // let onImagePicked: (UIImage) -> Void let onURLPicked: (URL) -> Void final class Coordinator: NSObject, UINavigationControllerDelegate, UIImagePickerControllerDelegate { @Binding private var presentationMode: PresentationMode private let sourceType: UIImagePickerController.SourceType private let onURLPicked: (URL) -> Void init(presentationMode: Binding<PresentationMode>, sourceType: UIImagePickerController.SourceType, onURLPicked: @escaping (URL) -> Void) { presentationMode = presentationMode self.sourceType = sourceType self.onURLPicked = onURLPicked } func imagePickerController( picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) { // let uiImage = info[UIImagePickerController.InfoKey.originalImage] as! UIImage // onImagePicked(uiImage) if let url = info[.mediaURL] as? URL{ onURLPicked(url) } presentationMode.dismiss() } func imagePickerControllerDidCancel(_ picker: UIImagePickerController) { presentationMode.dismiss() } } func makeCoordinator() -> Coordinator { return Coordinator(presentationMode: presentationMode, sourceType: sourceType, onURLPicked: onURLPicked) } func makeUIViewController(context: UIViewControllerRepresentableContext<VideoPicker>) -> UIImagePickerController { let picker = UIImagePickerController() picker.sourceType = sourceType picker.delegate = context.coordinator picker.mediaTypes = ["public.movie"] return picker } func updateUIViewController(_ uiViewController: UIImagePickerController, context: UIViewControllerRepresentableContext<VideoPicker>) { } }这段代码获取的url中绝对路径不准确

这可能是因为在 iOS 14 中，苹果公司修改了媒体选择器的行为，使其返回的 URL 是相对路径而不是绝对路径。要获取正确的绝对路径，你可以使用 `PHAsset` 和 `PHAssetResource` 来获取 URL，其中 `PHAssetResource` 包含了媒体文件的原始名称和 URL。

以下是一个获取视频绝对路径的示例代码：

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    guard let url = info[.mediaURL] as? URL else {
        return
    }
    
    let assets = PHAsset.fetchAssets(withALAssetURLs: [url], options: nil)
    guard let asset = assets.firstObject else {
        return
    }
    
    PHImageManager.default().requestAVAsset(forVideo: asset, options: nil) { (asset, _, _) in
        guard let asset = asset as? AVURLAsset else {
            return
        }
        
        let videoURL = asset.url
        // 处理视频URL
    }
    
    presentationMode.dismiss()
}

这个方法首先从选择器返回的 URL 中获取 `PHAsset` 实例，然后使用 `PHImageManager` 请求该资源的 `AVURLAsset`，最后从 `AVURLAsset` 中获取视频的绝对 URL。
