import Foundation
import SwiftUI
import AVKit
struct VideoPlayerView: UIViewControllerRepresentable {var videoURL: URL?// 创建UIViewControllerfunc makeUIViewController(context: Context) - AVPlayerViewController {let controller AVPlayerViewController()controller.player AVPlayer(url: videoURL!)controller.allowsPictureInPicturePlayback truecontroller.delegate context.coordinatorreturn controller}// 更新UIViewControllerfunc updateUIViewController(_ uiViewController: AVPlayerViewController, context: Context) {uiViewController.player AVPlayer(url: videoURL!)uiViewController.allowsPictureInPicturePlayback trueuiViewController.showsPlaybackControls true // 显示控制层if #available(iOS 14.2, *) {//进入后台时是否自动打开
// uiViewController.canStartPictureInPictureAutomaticallyFromInline true} else {// Fallback on earlier versions}}func makeCoordinator() - Coordinator {Coordinator(self)}class Coordinator: NSObject, AVPlayerViewControllerDelegate {var playerView: VideoPlayerViewinit(_ playerView: VideoPlayerView) {self.playerView playerView}func playerViewController(_ playerViewController: AVPlayerViewController, restoreUserInterfaceForPictureInPictureStopWithCompletionHandler completionHandler: escaping (Bool) - Void) {// 在这里你可以决定在退出画中画模式后是否保持在当前视图。// 这个例子中我们选择保持在当前视图。completionHandler(true)}}
}struct playView: View {var body: some View {VStack {VideoPlayerView(videoURL: URL(string: http://devimages.apple.com.edgekey.net/streaming/examples/bipbop_4x3/bipbop_4x3_variant.m3u8)!).frame(height: 400)}
// .onAppear {
// player.play()
// }
// .onDisappear {
// player.pause()
// }}
}
注意画中画只能在真机上运行xcode上的模拟器没有画中画功能
