A large variety of UIActivities have been published to provide support for additional services in iOS:

Why has no Flickr UIActivity been published? Googling yields almost no mention of this. I'm guessing there's something about the Flickr authentication that does not play nice with UIActivityController but I'd appreciate any additional info. Numerous blogs have reported 'possible' Flickr integration in iOS 7 but I can't wait for that and I'd prefer to use UIActivityController over ObjectiveFlickr or ShareKit. Thanks.
