屏幕旋转

Posted 2020-10-05 ArgenBarbie

    override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
        super.viewWillTransition(to: size, with: coordinator)
        coordinator.animate(alongsideTransition: { _ in
            
        }) { _ in
            //Put your code here
        }
    }

要在屏幕旋转之后进行的操作放在viewWillTransition的回调函数里。

 

viewDidLayoutSubviews可能多次被调用，或在其他地方被调用。
