PHPickerViewController 添加视频编辑屏幕 aka (UIImagePickerController.allowsEditing = true)

Question

I would like to edit/compress video after selection like it was in UIImagePickerController with allowsEditing = true .

Still the new PHPickerViewController doesn't have this property and Apple says that there is no such property anymore here . But there are apps in App Store that pushing "allowsEditing controller" after selecting asset from PHPickerViewController

Here is my PHPickerViewController implementation:

func openImagePicker() {
        if #available(iOS 14, *) {
            var configuration = PHPickerConfiguration()
            configuration.preferredAssetRepresentationMode = .automatic
            let picker = PHPickerViewController(configuration: configuration)

            // Set the delegate
            picker.delegate = self
            // Present the picker

            present(picker, animated: true)
        } else {
            // Fallback on earlier versions
            imagePicker?.photoGalleryAsscessRequest()
        }
    }

extension EditController: PHPickerViewControllerDelegate {
    @available(iOS 14, *)
    func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) {
        self.dismiss(animated: true)
   }
}

I investigated this issue but indeed there is no support for like as you mention allowsediting .

For example related to your question preset values for video edits was depreciated to UIImagePickerController.ImageURLExportPreset.compatible but There is no support for automatic compression. The picker will always pass the original video/image and it is up to the app to do the necessary compressions or edits. You can check this Apple Document: imageExportPreset .

Apple specifically mentions that we should be using this new one instead of the older UIImagePickerViewController. If someone wonder more: Meet the new Photos picker
