When needing to grant access to photos on iOS, the user can has three options: - Deny access to photos - Grant access to hand-picked photos\ - Grant access to all photos. Picking the middle option opens an OS-handled photo picker where you choose which photos the application can access. The model works pretty well in balancing flexibility, security and convenience. Something else _many_ apps support, is just pasting a photo. So if I want to post a photo on Twitter, I can just copy it from my photo app, and paste it there. Twitter has access to no photos on the system at all, it merely receives that one.
