Do like this
这样做
if let presentedViewController = self.storyboard?.instantiateViewController(withIdentifier: "menuC") {
presentedViewController.providesPresentationContextTransitionStyle = true
presentedViewController.definesPresentationContext = true
presentedViewController.modalPresentationStyle = UIModalPresentationStyle.overCurrentContext;
presentedViewController.view.backgroundColor = UIColor.init(white: 0.4, alpha: 0.8)
self.present(presentedViewController, animated: true, completion: nil)
}
