This is my attempt at the iOS part of the existing Screen Capture object for MMF2.
At the moment all it does is save the whole screen as a PNG to the device's Camera Roll (if device has a camera) or Photo Album folder when the Capture > Screen action is set. It ignores all the properties for the object too (can't figure out how to read the CFile without the original Screen Capture object source code)
Constructive feedback is welcome - hope somebody finds it useful.
Looking forward to adding more functionality - especially saving to other folders, eg Documents and/or Library/Cache so specific files can be loaded into the Active Picture object (which only loads from the bundle currently, as far as I can tell)
BTW this is my first extension!
