Requests asset information for beginning a content editing session.

options: Options affecting how Photos handles an edit session request.

Returns a numeric identifier for the request. Pass this identifier to the cancelContentEditingInputRequest method if you need to cancel the request before it completes.

When you call this method, Photos downloads the asset’s image or video data (if necessary) and prepares it for editing, then calls your completionHandler ddelegate to provide a PHContentEditingInputMBS object you use for editing.

To complete the edit, create a PHContentEditingOutputMBS object from the editing input to provide the edited asset data. Then, commit the edit by posting a change block to the shared PHPhotoLibrary object. In the block, create a PHAssetChangeRequestMBS object and set its contentEditingOutput property to the editing output you created.
