我想在人像模式下在闪屏中播放一些视频 - 全屏。这可能吗？请通过适当的解决方案指导我。如何在纵向模式下以全屏尺寸播放视频？

我在寻找迅速解决应用程序的委托

let splashScreenVC = viewController(withIdentifier: "identifier", inStoryboard: "storyboard:) as? SplashViewController 
window?.rootViewController = splashScreenVC

里面的视图控制器SplashViewController的

任何麻烦创建的UIView一个子类，具有AVPlayer和功能createBackground：

import AVFoundation 
class BackgroundVideo: UIView { 
    var player: AVPlayer? 
    func createBackground(name: String, type: String) { } 
}

那么你的createBackground可能是这样的：

实现视频循环

AVPlayerItemDidPlayToEndTime：10

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() 
}

那么您可以添加更多的东西，比如观察的通知。

UIApplicationWillEnterForeground用于控制视频循环，从后台恢复后。

最后你可能会附上这个BackgroundView，只要您需要：？假的闪屏，主屏幕，等等...

内didFinishLaunch方法，你可以在viewDidLoad方法播放视频。

func playVideo() { 
    guard let videoPath = Bundle.main.path(forResource: "Redtaxi-splash", ofType:"mov") else { 
     return 
    } 
    let videoURL = URL(fileURLWithPath: videoPath) 
    let player = AVPlayer(url: videoURL) 
    playerViewController = AVPlayerViewController() 
    playerViewController?.player = player 
    playerViewController?.showsPlaybackControls = false 
    playerViewController?.view.frame = view.frame 
    playerViewController?.view.backgroundColor = .white 
    playerViewController?.view.contentMode = .scaleAspectFill 
    NotificationCenter.default.addObserver(self, selector: #selector(playerDidFinishPlaying(note:)), 
              name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: player.currentItem) 
    view.addSubview((playerViewController?.view)!) 
    playerViewController?.player?.play() 
}

你不能这样做，在默认的启动画面，但你可以做一些变通方法，以达致这。

首先你应该把你的视频的第一帧，这将是图像。

你可以使用Photoshop或任何其他图形工具。

现在，您可以将它设置为UIImageView中的默认启动画面。

现在制作一个UIViewController并启动它作为初始视图控制器。

并在下面的代码，以播放视频

private func playFullScreenVideo() { 
    // drag your video file in project 
    // check if video file is available,if not return 
    guard let path = Bundle.main.path(forResource: "video", ofType:"mp4") else { 
     debugPrint("video.mp4 missing") 
     return 
    } 
    // create instance of videoPlayer with video path 
    let videoPlayer = AVPlayer(url: URL(fileURLWithPath: path)) 
    // create instance of playerlayer with videoPlayer 
    let playerLayer = AVPlayerLayer(player: videoPlayer) 
    // set its videoGravity to AVLayerVideoGravityResizeAspectFill to make it full size 
    playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill 
    // add it to your view 
    playerLayer.frame = self.view.frame 
    playerView.layer.addSublayer(playerLayer) 
    // start playing video 
    videoPlayer?.play() 
    }
