A container that provides information about and access to the image, video, or Live Photo content of an asset to be edited.

To edit an asset’s photo or video content:

1. Fetch a PHAsset object that represents the photo or video to be edited.
2. Call the asset’s requestContentEditingInputWithOptions method to retrieve a PHContentEditingInputMBS object.
3. Apply your edits to the asset. To allow a user to continue working with the edit later (for example, to adjust the parameters of a photo filter), create a PHAdjustmentDataMBS object describing the changes.
4. Initialize a PHContentEditingOutputMBS object. For photo- or video-only assets, use the editing output’s properties to provide edited asset data. For Live Photo assets, create a PHLivePhotoEditingContextMBS object to edit the Live Photo content.
5. Use a photo library change block to commit the edit. In the block, create a PHAssetChangeRequestMBS object and set its contentEditingOutput property to the editing output that you created. For more details, see PHPhotoLibraryMBS.

You can also edit assets from photo editing extensions. In this case, instead of working with a PHAsset object, you implement methods in the PHContentEditingControllerMBS protocol. Photos provides a PHContentEditingInputMBS object when your extension begins editing. When editing is complete, Photos requests a PHContentEditingOutputMBS object that contains the edited asset content.
