iOS开发中音频视频播放的简单实现方法

if let soundURL = Bundle.main.url(forResource: "sourceName", withExtension: "wav") {
 var mySound: SystemSoundID = 0
 AudioServicesCreateSystemSoundID(soundURL as CFURL, &mySound)
 // Play
 AudioServicesPlaySystemSound(mySound);
}

// 定义一个播放器属性
fileprivate var player: AVAudioPlayer?

func playMusic() {

 // 2.获取对应音乐资源
 guard let fileUrl = Bundle.main.url(forResource: "309769", withExtension: "mp3") else {
  return }
 // 3.创建对应的播放器
 do {
  player = try AVAudioPlayer(contentsOf: fileUrl)
 } catch {
  print(error)
 }

 // 设置代理监听播放完成
 player?.delegate = self

 // 4.准备播放
 player?.prepareToPlay()

 // 5.播放音乐
 player?.play()
}

// 停止、暂停
player?.stop()

// MARK: - AVAudioPlayerDelegate
extension ViewController: AVAudioPlayerDelegate {
 /// 完成播放
 func audioPlayerDidFinishPlaying(_ player: AVAudioPlayer, successfully flag: Bool) {
  if flag {
   print("播放完成")
  }
 }
}

func playVideo() {
 // 1.创建AVPlayer
 guard let url = URL(string: "http://baobab.wdjcdn.com/14559682994064.mp4") else { return }

 // 2.创建播放器
 // 提供数据,设置数据源
 let item = AVPlayerItem(url: url)
 // 负责控制播放,暂停、播放、指定时间播放等
 let player = AVPlayer(playerItem: item)

 // 3.创建图层,负责显示
 let layer = AVPlayerLayer(player: player)
 layer.frame = playerView.bounds
 playerView.layer.addSublayer(layer)

 // 4.播放视频
 player.play()
}

import IJKMediaFramework

func playVideoByIJKPlayer() {

 // 1.设置配置，打开硬解码
 let options = IJKFFOptions.byDefault()
 options?.setOptionIntValue(1, forKey: "videotoolbox", of: kIJKFFOptionCategoryPlayer)

 // 2.初始化播放器
 guard let ijkPlayer = IJKFFMoviePlayerController(contentURLString: "http://baobab.wdjcdn.com/14559682994064.mp4", with: options) else { return }
 ijkPlayer.view.frame = playerView.bounds
 playerView.addSubview(ijkPlayer.view)

 // 3.开始进行播放
 ijkPlayer.prepareToPlay()
}
