ios – ViewWillTransitionToSize在Swift 3中爆发了吗？

当我旋转设备时,我正在使用viewWillTransitionToSize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!
        })
    }

看起来我在旋转设备时没有被调用？

解决方法

弄清楚问题是什么,迁移到swift 3所做的更改是不正确的,并且函数应该如下所示：

override func viewWillTransition(to size: CGSize,with coordinator: UIViewControllerTransitionCoordinator) {
        super.viewWillTransition(to: size,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!
        })

    }
