How to crop image after taken from UIImagePicker Camera?

Question

I'm trying to allow the user to take 16x9 aspect ratio images to look like they are nice HD photos. I'm using the cameraViewOverlay to overlay black bars on both ends, but when the image is taken, how do I crop the top and bottom without resizing or changing the scale of the image?

Thanks.

There are various posts around on how to scale/crop a UIImage you get back from the camera, like this one.

It's a little trickier than you'd expect, because camera images are rotated, so you have to think about rotations even if you're just cropping.
