如何在纵向模式下以全屏大小播放视频？

Question

我想在纵向模式下在启动画面中播放一些视频 - 全屏.那可能吗？请引导我通过适当的解决方案.

我正在寻找快速的解决方案

Answer 1

UIView使用a AVPlayer和函数创建一个子类createBackground:

import AVFoundation

class BackgroundVideo: UIView {
  var player: AVPlayer?

  func createBackground(name: String, type: String) { }
}

然后你createBackground可能是这样的:

func createBackground(name: String, type: String) {
  guard let path = Bundle.main.path(forResource: name, ofType: type) else { return }

  player = AVPlayer(url: URL(fileURLWithPath: path))
  player?.actionAtItemEnd = AVPlayerActionAtItemEnd.none;
  let playerLayer = AVPlayerLayer(player: player)
  playerLayer.frame = self.frame
  playerLayer.videoGravity = AVLayerVideoGravity.resizeAspectFill
  self.layer.insertSublayer(playerLayer, at: 0)
  player?.seek(to: kCMTimeZero)
  player?.play()
}

然后你可以添加更多的东西,比如观察通知:

• AVPlayerItemDidPlayToEndTime 用于实现视频循环.
• UIApplicationWillEnterForeground 用于控制视频循环,从后台恢复后.

最后你可以BackgroundView在任何需要的地方附上这个:虚假的闪屏,主屏幕......等等......
