AVFoundation capture UIImage

Question

I'm trying to capture one or more UIImages programmatically using AVFoundation. I set up the sessions and input devices and everything, but when I try to find explanations on how to actually take the photos, all I get is buffeled information about connections and what not. I couldn't find a single example of actually taking photos and saving it to UIImage for further processing. All the example use a constant kCGImagePropertyExifDictionary Which doesn't seems to exist in iOS 5 SDK..

Can someone please provide me with a code or an explanation from top to bottom on how to take and save an image from the front facing camera to a UIImage using AVFoundation?

Thanks alot!

Answer 1

To use kCGImagePropertyExifDictionary, you should #import <ImageIO/ImageIO.h>.

All of the other information you seek is inside the AVFoundation Programming guide - particularly the Media Capture section.
