I've tried using kvo with a key 'image' on the image view, but image is not a property, so I don't get notified of, for example, the image being rotated. KVO does work for the 'imageProperties' of the image view, but not for rotation, cropping, etc. How can one build a sensible UI for an IKImageView if you don't know when the image has been edited?

Great, thanks. Unfortunately there isn't a callback for rotation of the image. Do you know how these delegate methods were discovered, and if there could be more of them lurking somewhere? This seems like a rather big omission from the documentation.
Cheers,
