So this almost provides the answer. I made a subclass and in there override setRotationAngle:centerPoint: but this triggers for every mouse movement, rather than for an accumulated drag from the user. I then tried to override mouseUp with the plan to set a flag didRotate in setRotationAngle:centerPoint: and then send a delegate message or notification on mouseUp, then reset the flag. Unfortunately IKImageView doesn't receive a mouseUp: when rotating. This works for moving the image, but not rotating. So I guess for now I will try to live with the many messages to the delegate, but I would have liked to quantise this at the level of the user's action, so bracketed by mouseDown: and mouseUp:. If anyone has any ideas how this might be achieved, I'd be happy to hear them.
Cheers,
Martin
