将AVPlayerViewController嵌入到UIView中

Question

我试图在UIView中播放视频,但视频播放器总是出现在我嵌入AVPlayerViewController的UIView之外.

以下是我到目前为止所拥有的......

class ViewController: UIViewController {

    let smallVideoPlayerViewController = AVPlayerViewController()

    @IBOutlet weak var videoView: UIView!

    override func viewDidLoad() {
        super.viewDidLoad()

        let myFileManager = FileManager.default
        let mainBundle = Bundle.main
        let resourcesPath = mainBundle.resourcePath!

        guard let allItemsInTheBundle = try? myFileManager.contentsOfDirectory(atPath: resourcesPath) else {
            return
        }

       let videoName = "test"

       let videoPath = Bundle.main.path(forResource: videoName, ofType: "mp4")
       let videoUrl = URL(fileURLWithPath: videoPath!)

       smallVideoPlayerViewController.showsPlaybackControls = false
       smallVideoPlayerViewController.player = AVPlayer(url: videoUrl)

       videoView.addSubview(smallVideoPlayerViewController.view)

       smallVideoPlayerViewController.view.frame = videoView.frame

       smallVideoPlayerViewController.player?.play()
    }
 ...
}

UIView的背景颜色设置为白色.从屏幕截图中可以看出,AVPlayer不在UIView中.

我尝试手动设置AVPlayer的尺寸和位置,但也没有运气.

我正在使用Xcode 9.2.该项目没有任何布局问题的警告.

如何完美地对齐AVPlayer,这样就会出现在UIView中.

谢谢

改变这一行:

smallVideoPlayerViewController.view.frame = videoView.frame

对此:

smallVideoPlayerViewController.view.frame = videoView.bounds

原因是因为videoView.frame在其超级视图中包含了您不想要的原点.videoView.bounds只是原点为0,0的大小.

当然你可能想进一步设置自动调整大小掩码,以保持视频播放器框架像这样:

smallVideoPlayerViewController.view.autoresizingMask = [.flexibleWidth, .flexibleHeight]

甚至是全面的自动布局.
