循环iOS14 VideoPlayer

Question

我是SwiftUI的新手，我不太确定如何在iOS 14上使用VideoPlayer循环视频，而且我找到的文档也很少。我发现的大多数解决方案在很多方面都非常复杂和令人困惑。如果有人能帮上忙，我将不胜感激。

VideoPlayerHelper.swift文件

import Foundation
import AVKit
//AutoPlay Video
var videoPlayer: AVPlayer?

func playVideo(fileName: String, fileFormat: String) -> AVPlayer {
    if Bundle.main.url(forResource: fileName, withExtension: fileFormat) != nil {
        videoPlayer = AVPlayer(url: Bundle.main.url(forResource: fileName, withExtension: fileFormat)!)
//        videoPlayer?.play()
        
    }
    return videoPlayer!
}

VideoPlayerView.swift文件

import SwiftUI
import AVKit

struct VideoPlayerView: View {
    // MARK: - PROPERTIES
    var videoSelected: String
    var videoTitle: String
    
    // MARK: - BODY
    var body: some View {
        VStack {
            VideoPlayer(player: playVideo(fileName: videoSelected, fileFormat: "mp4"))
} }

非常感谢！

基本上，您添加了一个通知观察者onAppear，每次播放器结束时，您将时间设置为0，然后再次开始播放。

struct VideoPlayerView: View {
    @State var player = AVPlayer(url: Bundle.main.url(forResource: "YourURL", withExtension: "mp4")!)
   var body: some View {
       VideoPlayer(player: player)
               .frame(width: 400, height: 300, alignment: .center)
               .onAppear {
                   NotificationCenter.default.addObserver(forName: .AVPlayerItemDidPlayToEndTime, object: nil, queue: .main) { _ in
                       player.seek(to: .zero)
                       player.play()
                   }
               }
     
   }
}
