ios - swift 3 - 旋转到横向时全屏播放视频

Question

我有一个容器 View ，当设备为纵向时，它会在其中播放视频。我希望视频在设备旋转时自动全屏播放。我已经尝试过这段代码来检测设备何时旋转，但它不会将容器更改为全屏

override func willTransition(to newCollection: UITraitCollection, with coordinator: UIViewControllerTransitionCoordinator) {

    if (UIDevice.current.orientation.isLandscape) {

        videoContainerView.frame = self.view.frame
       // self.videoContainerView.frame = CGRect(x: 0, y: 0, width: self.view.frame.width, height: self.view.frame.height) // this didn't work to....
        print("Device is landscape")
    }
    else{
        print("Device is portrait")
    }

}

视频在 avplayer 播放器上播放。谢谢

我找到了另一种更好的方法来解决这个问题，因为这样控件是可见的。主要思想是将 AVPlayerViewController 对象移动到一个新的 subview 并将其框架设置为全屏。这是我的代码..

override func willTransition(to newCollection: UITraitCollection, with coordinator: UIViewControllerTransitionCoordinator) {

    if (UIDevice.current.orientation.isLandscape) {


                    DispatchQueue.main.async {
                        self.playerController.player = self.player
                        self.addChildViewController(self.playerController)
                        self.view.addSubview(self.playerController.view)
                        self.playerController.view.frame = self.view.frame

        }
        print("Device is landscape")
    }

当设备旋转回纵向时，将此 subview 添加到上一帧并再次设置其大小。这是我的代码。

else{
        print("Device is portrait")
        videoContainerView.addSubview(playerController.view)
        playerController.view.frame = videoContainerView.bounds
        controllsContainerView.frame = videoContainerView.bounds
    }
}

希望对您有所帮助。祝你好运!
