A request to create a new Photos asset from underlying data resources, for use in a photo library change block.

A PHAssetCreationRequestMBS object, used within a photo library change block, constructs a new photo or video asset from data resources, and adds it to the Photos library. This class works in terms of the raw data resources that together form an asset, so you can use it together with the PHAssetResource class to perform a complete copy (or backup and restore) of an asset’s underlying resources. To instead simply create a new asset from an image object, image file, or video file, see the superclass PHAssetChangeRequestMBS.

To create a new asset from data resources, first start a change block using the shared PHPhotoLibraryMBS method performChanges or performChangesAndWait. Then, within the change block:

1. Within the change block, create a new asset creation request with the creationRequestForAsset method.
2. Add image, video, or data resources using the methods listed in Providing Data Resources for the New Asset.
3. (Optional.) Set metadata for the new asset using methods and properties of the superclass PHAssetChangeRequestMBS.

After Photos runs the change block and calls your completion handler, the new asset is created in the Photos library.
If you instantiate or use this class outside a photo library change block, Photos throws an exception. For details on change blocks, see PHPhotoLibrary.
Subclass of the PHAssetChangeRequestMBS class.
This is an abstract class. You can't create an instance, but you can get one from various plugin functions.
