After adding the Camera Roll and Photo Stream albums, Apple added the following PHAssetCollectionSubtype
types in iOS 8.1:
-
PHAssetCollectionSubtypeAlbumMyPhotoStream
(together withPHAssetCollectionTypeAlbum
) – fetches the Photo Stream album. -
PHAssetCollectionSubtypeSmartAlbumUserLibrary
(together withPHAssetCollectionTypeSmartAlbum
) – fetches the Camera Roll album.
Haven’t tested if this is backward-compatible with iOS 8.0.x though.
