一，代码:
import SwiftUI
import AVFoundationstruct Mp3View: View {// 1. 创建一个持久化的播放器实例@State private var player: AVPlayer?let mp3Url = "https://hanyu-poem-voice.cdn.bcebos.com/man/38a52978fb6f4cfd8bcc25fc2db2c0fa.mp3" // 替换为真实的在线MP3地址var body: some View {VStack(spacing: 20) {Button(action: {playAudio(url: mp3Url)}) {Label("播放音乐", systemImage: "play.circle.fill").font(.title).padding().background(Color.blue).foregroundColor(.white).cornerRadius(10)}Button(action: {player?.pause()}) {Label("暂停", systemImage: "pause.circle.fill").font(.title).padding().background(Color.blue).foregroundColor(.red).cornerRadius(10)}}}// 2. 播放逻辑func playAudio(url: String) {guard let url = URL(string: url) else { return }// 如果播放器不存在，则初始化；如果已存在，直接播放if player == nil {player = AVPlayer(url: url)}player?.play()}
}
二，运行效果:
