AVPlayerLayer帧不适合视频播放器的UIView

Question

我尝试使用以下代码显示视频：

self.videoPlayer = AVPlayer.init(url: videoUrl as URL)
let playerLayer = AVPlayerLayer.init(player: self.videoPlayer)
self.videoPlayerView.layer.addSublayer(playerLayer)
playerLayer.frame =  self.videoPlayerView.layer.bounds
self.videoPlayer.play()

但它没有出现在UIView内（即self.videoPlayerView）。它只是在屏幕中间显示一个瘦Rect，如屏幕截图所示。我该如何解决？ screen shot

Answer 1

试试这个...... 将图层的框架设置为等于视图的框架

self.videoPlayer = AVPlayer.init(url: videoUrl as URL)
let playerLayer = AVPlayerLayer.init(player: self.videoPlayer)
self.videoPlayerView.layer.addSublayer(playerLayer)
playerLayer.frame =  self.videoPlayerView.frame
self.videoPlayer.play()

Answer 2

首先代码是Swift not Obective-C，我会改变那个标签！其次，如何定义videoPlayerView框架？第三，你已经添加了playerLayer的框架。因此框架不会在视觉上改变！在将其添加为subLayer之前设置框架。希望有所帮助。
