The documentation states:
- (ALAssetRepresentation *)defaultRepresentation
This method returns nil for assets from a shared photo stream that are not yet available locally. If the asset becomes available in the future, an ALAssetsLibraryChangedNotification notification is posted.
How can you request a download for a shared photo? I first thought a user had to go to the photo's app to achieve it, but in the Telegram.app they were able to achieve it so it is possible for a third party app. Does anyone know how?
