How to force view controller orientation in iOS 8?

Question

Before iOS 8, we used below code in conjunction with supportedInterfaceOrientations and shouldAutoRotate delegate methods to force app orie

Answer 1

The combination of Sids and Koreys answers worked for me.

Extending the Navigation Controller:

extension UINavigationController {
    public override func shouldAutorotate() -> Bool {
        return visibleViewController.shouldAutorotate()
    }
}

Then disabling rotation on the single View

class ViewController: UIViewController {
    override func shouldAutorotate() -> Bool {
        return false
    }
}

And rotating to the appropriate orientation before the segue

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if (segue.identifier == "SomeSegue")
    {
        let value = UIInterfaceOrientation.Portrait.rawValue;
        UIDevice.currentDevice().setValue(value, forKey: "orientation")
    }
}
