How to disable auto rotate

[boboxiaodd]

i set Device Orientation is Portrait , but when the XLActionController show , it can auto rotate ,
i use PeriscopeActionController style , but PeriscopeActionController is not open class , i can't override it,
i must add these code to class ActionController:

 override open var supportedInterfaceOrientations: UIInterfaceOrientationMask{
        get{
            return .portrait
        }
    }
