在swift中，视频不能在给定视图中全屏播放。我需要帮助来修复它

Question

我有一个视图，播放应用程序中的视频。给出的约束是正确的，但在像iPhone 11，iPhone 11 pro这样的设备中，视图在后端留下了一些空间。添加截图以供参考。

​

*需要帮助将视频显示设置为全视图。

约束:对齐尾部安全区域对齐顶部安全区域对齐前导安全区域高度等于- 150

代码：

import UIKit
import AVFoundation
    
class VideoViewController: UIViewController {
@IBOutlet weak var videoView: UIView!  
    
var player: AVQueuePlayer!
var playerItem: AVPlayerItem!
var playerLooper: AVPlayerLooper!
    
override func viewDidLoad() {
   super.viewDidLoad()
    videoView()
}

func videoViewForLogin() {
//video 
 guard let url = Bundle.main.url(forResource: "splashpanoslice", withExtension: "mp4") else {return}
let playerPath = AVPlayer(url: url)
player = AVQueuePlayer()
let playerLayer = AVPlayerLayer(player: player)
playerItem = AVPlayerItem(url: url)
let duration = Int64( ( (Float64(CMTimeGetSeconds(AVAsset(url: url).duration)) *  10.0) - 1) / 10.0 )
playerLayer.frame = videoView.bounds
playerLooper = AVPlayerLooper(player: player, templateItem: playerItem,                                          timeRange: CMTimeRange(start: CMTime.zero, end: CMTimeMake(value: duration, timescale: 1)) )
playerLayer.videoGravity = .resizeAspectFill
         videoView.layer.insertSublayer(playerLayer, at: 1)
player.play()
  }
}

既然你正在使用框架，我认为你应该尝试将布局代码移到比viewDidLoad()更晚的地方。当视图大小被确定并且当显示参数改变(例如，屏幕方向已经改变)时也无效时，可能是viewDidLayoutSubviews()。
