UIImagePickerController Image Orientation

Question

Can anyone tell me how to use the UIImagePickerController (camera and album) delegates determine the image\'s orientation, rotate accordingly, and assign it to a UIImageView

Answer 1

Vodkhang's answer is partially incorrect - modern cameras put an explicit orientation into the image when they take the photo. This has been common for about 5+ years now.

I've previously used the code in this answer to do the rotation by reading the "orientation" info direct from the picture:
