UIImagePickerController didFinishPickingMediaWithInfo Orientation

Question

On iOS 5 using an iPhone 4s I am trying to pick a photo from the camera roll using UIImagePickerController. The problem I am having is that the image that I pick always has the following attributes (regardless of wether the image is portrait or landscape):

image.size.width = 3264
image.size.height = 2448
image.orientation = UIImageOrientationUp

The UIImage returned from didFinishPickingMediaWithInfo does not seem to give me access to the orientation of the photo.

Is there something a UIImageView uses other than UIImage.UIImageOrientation to specify either a landscape or portrait photo?

Im not using a UIImageView to display the photo so I need to figure out what UIImageView is doing to correct the orientation.

Thanks

Read this: UIImagePickerController Image Orientation

I use the category UIImage+Resize to get the correct orientation after picking the image

In my case I was using the CGImage which does not keep the orientation info.

Thanks for the reply Kapil that is the problem. Regardless of whether the image is landscape or portrait width is always 3264 and height is always 2448. – Skeep Mar 07 '12 at 10:01
Orientation has nothing to do with width and height, and `UIImageOrientation` has eight different values, not just portrait and landscape. – Eran Goldin Dec 10 '15 at 14:18
