How to rotate orientation programmatically in Swift?

Question

I tried the next:

UIDevice.currentDevice().setValue(UIInterfaceOrientation.Portrait.rawValue, forKey: \"orientation\")

on

Answer 1

You can override UIViewController.supportedInterfaceOrientations() instead of triggering rotation in viewWillAppear

For Xcode 7

override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
    return UIInterfaceOrientationMask.Landscape
}

For Xcode 6

override func supportedInterfaceOrientations() -> Int {
    return Int(UIInterfaceOrientationMask.Landscape.rawValue)
}

And make sure the desired orientations are enabled in project settings.
