MFMailComposeViewController image orientation

UIImage has a property which describes its orientation at the time the image was captured and you can get it like this UIImageOrientation orient image.imageOrientation Note that the orientation property does not describe how the data in the UIImage is physically.. to rotate it so it will appear correctly. If you capture an image in portrait mode image.imageOrientation will return UIImageOrientationRight. This tells displaying software that it needs to rotate the image 90 degrees so it will display correctly. Be clear.. UIImage which remains as 3264w x 2448h. If you capture an image in landscape mode image.imageOrientation will return UIImageOrientationUp. UIImageOrientationUp tells displaying software that the image is fine to display as it is no rotation is necessary. Again..
