ios - Native camera（通过 UIImagePicker 调用相机）的质量如何更改为 4K？

Question

我正在尝试通过 UIImagePicker 调用相机，如下所示，

 if UIImagePickerController.isSourceTypeAvailable(.camera) {
            let imagePicker = UIImagePickerController()
            imagePicker.delegate = self
            imagePicker.sourceType = .camera
            imagePicker.mediaTypes = [kUTTypeMovie as String]
            imagePicker.cameraCaptureMode = .video
            imagePicker.allowsEditing = false
            imagePicker.videoQuality = .typeHigh
            imagePicker.videoExportPreset = AVAssetExportPreset3840x2160
            helperGetAppDeleate().navigation.present(imagePicker, animated: true, completion: nil)
 }

videoQuality 为 .typeHigh。虽然我的手机支持 4k，但 videoQuality 似乎没有增加超过 1920x1080。除此之外，videoExportPreset 已被弃用，我无法使用它。

有任何想法吗？
