Something like that will work to write the contents of image, whatever it is,
to a file.
NSData *data = UIImagePNGRepresentation( image );
[ data writeToURL:fileURL atomically:YES ];
But how are you rotating the image, are you actually making a bitmap context
and rotating it and drawing it into the context? If so you don't have to
necessarily do that, you can start with the unrotated image, probably in a
UIImageView just set a transform on the UIImageView and that will show it
rotated. Which means you just save the original image and the rotation angle
again and .. when you need it back you load up the original image into a new
UIImageView and add that, rotated to your view.
Your original question is a bit vague so it's not easy to figure out what you
REALLY want to do.
