Swift version:

//AppDelegate:
    func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> Int {

        var presentedVC = application.keyWindow?.rootViewController
        while let pVC = presentedVC?.presentedViewController
        {
            presentedVC = pVC
        }
        if let pVC = presentedVC
        {
            if contains(["MPInlineVideoFullscreenViewController", "MPMoviePlayerViewController", "AVFullScreenViewController"], pVC.nameOfClass)
            {
                return Int(UIInterfaceOrientationMask.AllButUpsideDown.rawValue)
            }
        }

        return Int(UIInterfaceOrientationMask.Portrait.rawValue)
    }

//Extension:
public extension NSObject{
    public class var nameOfClass: String{
        return NSStringFromClass(self).componentsSeparatedByString(".").last!
    }

    public var nameOfClass: String{
        return NSStringFromClass(self.dynamicType).componentsSeparatedByString(".").last!
    }
}

//View controller:
    override func supportedInterfaceOrientations() -> Int {
        return Int(UIInterfaceOrientationMask.Portrait.rawValue)
    }

    override func preferredInterfaceOrientationForPresentation() -> UIInterfaceOrientation {
        return UIInterfaceOrientation.Portrait
    }

    override func shouldAutorotate() -> Bool {
        return false
    }

    override func viewWillLayoutSubviews() {
        UIApplication.sharedApplication().setStatusBarHidden(false, withAnimation: UIStatusBarAnimation.None)
    }
