Before editing an asset, use its canPerformEditOperation method to see if the asset allows editing.

After Photos runs your change block, the asset’s properties reflect your changes. For details on change blocks, see PHPhotoLibraryMBS.

To edit an asset’s image or video content, first begin a content editing session with the asset’s requestContentEditingInputWithOptions method.
