Question

我在旋转设备时使用viewWillTransitionToSize来调整我的滑出菜单，但它似乎在Swift 3中被打破了？有人能为我解决这个问题吗？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!
        })
    }

旋转设备时似乎没有调用它？

弄清楚问题是什么，迁移到swift 3所做的更改是不正确的，而且函数看起来应该是这样的：

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!
        })

    }

ViewWillTransitionToSize在Swift 3中爆发了吗？
