Question

我正在播放的视频不占用UIView（名为videoView）的整个区域，该区域为灰色：iPhone 7 Plus Simulator Screenshot

大多数答案声称我需要将框架设置为边界（UIView）或将videoGravity设置为AVLayerVideoGravityResizeAspectFill。我已经尝试了两种方法，但由于某种原因，它仍然没有完全填满这个空间。

var avPlayer: AVPlayer!
var avPlayerLayer: AVPlayerLayer!
var paused: Bool = false

@IBOutlet weak var videoView: UIView!

override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.
    let theURL = Bundle.main.url(forResource:"HOTDOG", withExtension: "mp4")

    avPlayer = AVPlayer(url: theURL!)
    avPlayerLayer = AVPlayerLayer(player: avPlayer)

    avPlayerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
    avPlayerLayer.frame = videoView.layer.bounds

    videoView.layer.insertSublayer(avPlayerLayer, at: 0)
}

任何帮助将不胜感激。：）

Answer 1

经过很长一段时间我找到了答案。

下面的代码应该移到viewDidAppear（）中，如：

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)

    // Resizing the frame
    avPlayerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
    avPlayerLayer.frame = videoView.layer.bounds
    videoView.layer.insertSublayer(avPlayerLayer, at: 0)

    avPlayer.play()
    paused = false
}

布局是为iPhone SE（小屏幕）设计的，所以当它在更大的屏幕上测试时，应用程序从自动布局中取出原始设置的大小并根据它进行整形。通过将代码移动到viewDidAppear（）中，应用程序根据新约束调整窗口大小。

只需将框架线#==== connect to postgreSQL ======# spring.jpa.hibernate.ddl-auto=create-drop spring.datasource.url=jdbc:postgresql://localhost:5432/rs_ecommerce spring.datasource.username=postgres spring.datasource.password=password spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect # Disable feature detection by this undocumented parameter.

viewDidLayoutSubviews

其余部分应该像您一样坚持使用override func viewDidLayoutSubviews() { super.viewDidLayoutSubviews() avPlayerLayer.frame = videoView.layer.bounds }函数。

AVPlayerLayer没有完全填充UIVIew。我错过了什么？
