Fun Fact, Photoshop Touch does this to open your camera roll. Ordinarily, the asset library APIs can only see albums.
The only other way to get at the camera roll was to use the official UIPopover from Apple. Currently my apps do this. I’ve been investigating writing my own controller because the popover is limited. Now it seems like Apple is going to fix this and there will be no possible alternative way to load photos from the camera roll. Maybe this is OK for some apps, but not for mine.
My only hope is that Apple enhances the “blessed” method of getting photos and provides more delegate methods.
