Answer 1

In swift I use:

override func willAnimateRotationToInterfaceOrientation(toInterfaceOrientation: UIInterfaceOrientation, duration: NSTimeInterval) {
    if !UIDevice.currentDevice().model.contains("Simulator") {
        if (toInterfaceOrientation == .Portrait) {
            prevLayer?.transform = CATransform3DMakeRotation(0, 0, 0, 1)
        } else if (toInterfaceOrientation == .LandscapeLeft) {
            prevLayer?.transform = CATransform3DMakeRotation(CGFloat(M_PI)/2, 0, 0, 1)
        } else if (toInterfaceOrientation == .LandscapeRight) {
            prevLayer?.transform = CATransform3DMakeRotation(-CGFloat(M_PI)/2, 0, 0, 1)
        }
        prevLayer?.frame = self.scanView.frame
    }
}
