iPhone SDK - What is the fastest way to grap an image from the camera and resize it to screen size?

Since UIGetScreenImage() is banned again I'm looking for another开发者_如何学C fast way to get a 320x480 image representation of the current camera picture.

What would be the fastest way to downsize the image from didFinishPickingMediaWithInfo and save it as an jpg?


You can access camera using AVFoundation tools as shown here
