FilterOptionGroup class

A collection of filtering and sorting options for querying assets.

Use this class to specify how to filter and sort a set of assets returned by PhotoManager.

The FilterOptionGroup object contains several FilterOption objects, one for each type of asset (image, video, audio). You can set specific filtering and sorting options for each type of asset using the corresponding FilterOption object.

Additionally, you can specify whether to include modified path results, whether to include live photos, or whether to only include live photos, using the appropriate properties of this object.

Finally, you can use the orders property to specify sorting options for the results.
