Question

我有一个容器视图，当设备是纵向时，它会在其中播放视频。我希望视频在旋转设备时自动播放全屏。我已经尝试过这段代码，可以检测设备何时旋转，但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")
    }

}

视频播放在avplayer播放器上。感谢的

O.k。所以我设法通过将视频添加到AVPlayerLayer并在设备风景时将其大小设置为视图来全屏播放视频。

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

    if (UIDevice.current.orientation.isLandscape) {

                    DispatchQueue.main.async {
                       self.view.didAddSubview(self.controllsContainerView)
                       self.layer = AVPlayerLayer(player: self.player!)
                        self.layer?.frame = self.view.frame
                        self.layer?.videoGravity = AVLayerVideoGravityResizeAspectFill
                        self.view.layer.addSublayer(self.layer!)

        }
        print("Device is landscape")
    }

当UIDevice.cuurent.orientation.islandscape == false时，我删除了subLayer并将视图设置回videoContainer边界。

else{
        print("Device is portrait")
        movie.view.frame = videoContainerView.bounds
        controllsContainerView.frame = videoContainerView.bounds
        self.layer?.removeFromSuperlayer()


    }

希望它可以帮助任何人。

我找到了解决这个问题的另一种更好的方法，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子视图，并将它的帧设置为全屏。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，将此子视图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
    }
}

希望它有所帮助。祝你好运！

这就像我使用AVQueuePlayer一样对我有用：

override func willTransition(to newCollection: UITraitCollection, with coordinator: UIViewControllerTransitionCoordinator) {
    super.willTransition(to: newCollection, with: coordinator)
    DispatchQueue.main.async {
        if (UIDevice.current.orientation.isLandscape) {
            self.landScapeAVController           = AVPlayerViewController()
            self.addChild(self.landScapeAVController!)
            self.landScapeAVController!.player   = self.queuePlayer
            self.landScapeAVController!.view.tag = 999
            self.view.addSubview(self.landScapeAVController!.view)
        } else {
            let topView                          = self.view.viewWithTag(999)
            topView?.removeFromSuperview()
            self.landScapeAVController?.removeFromParent()
        }
    }
}
