Try GMImagePicker. It uses the new Photos framework (PhotoKit) which gives you access to iOS 8's photo hierarchy. You're going to have to customize it a bit, though.
In Apple's documentation:
Use the PHCollectionList class to find assets corresponding to the
Moments hierarchy in the Photos App
So somewhere around here you'll want to call one of the fetchCollectionLists functions like fetchCollectionListsWithType:subtype:options: with type PHCollectionListTypeMomentList. You'll have another PHFetchResult to treat as an album the way the author does here.
If I have time I'll edit this with a more thorough answer, but I think it'll be fun and educational to learn the Photos framework and work on this yourself.
