I read the API docs again for ALAssetsLibrary, and discovered the following:
ALAssetsGroupSavedPhotos - All the photos in the Camera Roll.
ALAssetsGroupAlbum - All the albums created on the device or synced from iTunes,
not including Photo Stream or Shared Streams
So I'm guessing that ALAssetsLibrary is indeed the Class I use to iterate through all photos in the Camera Roll. Can someone pls confirm that this is all I need to get access?
[ALAssetsLibrary authorizationStatus] == ALAuthorizationStatusAuthorized;
