如何在iOS上使用AVAudioPlayer播放指定持续时间的声音？

import AVFoundation

var audioPlayer: AVAudioPlayer?

if let url = Bundle.main.url(forResource: "audio_file", withExtension: "mp3") {
    do {
        audioPlayer = try AVAudioPlayer(contentsOf: url)
    } catch {
        print("Error initializing audio player: \(error.localizedDescription)")
    }
} else {
    print("Audio file not found")
}

audioPlayer?.numberOfLoops = 0 // 设置循环次数，0表示不循环
audioPlayer?.volume = 1.0 // 设置音量，范围为0.0到1.0
audioPlayer?.play() // 开始播放

DispatchQueue.main.asyncAfter(deadline: .now() + 5.0) {
    self.audioPlayer?.stop()
}

audioPlayer?.stop()
audioPlayer = nil
