Disable autorotate on a single subview in iOS8

Question

I\'m writing a drawing app and I don\'t want the drawing view to rotate. At the same time, I want other controls to rotate nicely depending on the orientation of the device.

Answer 1

Dimitri's answer worked perfectly for me. This is the swift version of the code in case someone needs it...

override func viewWillTransitionToSize(size: CGSize, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) {
  let targetRotation = coordinator.targetTransform()
  let inverseRotation = CGAffineTransformInvert(targetRotation)

  coordinator.animateAlongsideTransition({ context in
    self.drawingView.transform = CGAffineTransformConcat(self.drawingView.transform, inverseRotation)
    self.drawingView.frame = self.view.bounds
    context.viewControllerForKey(UITransitionContextFromViewControllerKey)
  }, completion: nil)
}
