如何在iOS中获取音频文件的持续时间？

import AVFoundation

let audioPlayer = try? AVAudioPlayer(contentsOf: audioFileURL)

let duration = audioPlayer?.duration

let minutes = Int(duration! / 60)
let seconds = Int(duration! % 60)

import AVFoundation

func getAudioDuration(audioFileURL: URL) -> (minutes: Int, seconds: Int) {
    let audioPlayer = try? AVAudioPlayer(contentsOf: audioFileURL)
    let duration = audioPlayer?.duration
    let minutes = Int(duration! / 60)
    let seconds = Int(duration! % 60)
    return (minutes: minutes, seconds: seconds)
}

let audioFileURL = Bundle.main.url(forResource: "audio_file_name", withExtension: "mp3")!
let duration = getAudioDuration(audioFileURL: audioFileURL)
print("音频文件的持续时间：\(duration.minutes)分钟\(duration.seconds)秒")
