ViewWillTransitionToSize 在 Swift 3 中出现故障？

Question

当我旋转设备时，我正在使用 viewWillTransitionToSize 来调整我的滑出菜单，但是它似乎在 Swift 3 中被破坏了？谁能帮我解决这个问题？我的代码如下所示：

func viewWillTransitionToSize(size: CGSize, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) {
        super.viewWillTransition(to: size, with: coordinator)
        coordinator.animate(alongsideTransition: nil, completion: {
            _ in

            let controller = self.revealViewController().rightViewController

            var frame = controller?.view.frame
            frame?.size.height = UIScreen.main.bounds.size.height - self.navigationController!.navigationBar.frame.size.height - self.toolBar.frame.size.height - (UIApplication.shared.isStatusBarHidden ? 0 : 20)
            controller?.view.frame = frame!
        })
    }

旋转设备时好像没有调用它？

找出问题所在，迁移到 swift 3 所做的更改不正确，函数应如下所示：

override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
        super.viewWillTransition(to: size, with: coordinator)
        coordinator.animate(alongsideTransition: nil, completion: {
            _ in

            let controller = self.revealViewController().rightViewController

            var frame = controller?.view.frame
            frame?.size.height = UIScreen.main.bounds.size.height - self.navigationController!.navigationBar.frame.size.height - self.toolBar.frame.size.height - (UIApplication.shared.isStatusBarHidden ? 0 : 20)
            controller?.view.frame = frame!
        })

    }
