3.5.2 屏幕旋转的处理
//1.在控制器的viewDidLoad() 适当的地方注册通知监听者
//设置UIDevice方向变化监听的通知
NotificationCenter.default.addObserver(self,selector:#selector(receivedRotation(notification)),
name:NSNotification.Name.UIDevceOrientationDidChange,object:nil)
//2.处理旋转过程中需要的操作
//UIDevice旋转方向通知监听触发的方法
func receivedRotation(notification:NSNotification){
    backgroundView.frame=CGRect(x:0,y:0,width:self.view.frame.size.width,height:self.view.frame.size.height)
}
