从文档目录播放m4a文件 [英] Play m4a file from document Directory

问题描述

我想播放一个m4a文件，但在控制台中出现错误，该文件将无法播放.

I would to play an m4a file but I'm getting an error in the console and the file won't play.

控制台打印:

操作无法完成. (OSStatus错误2003334207.)

The operation couldn’t be completed. (OSStatus error 2003334207.)

let url = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
print("File Location: ",url.path)

if(FileManager.default.fileExists(atPath: url.path)) {
   do {
       audioPlayer = try AVAudioPlayer(contentsOf: url)
       guard let player = audioPlayer else { return }

       player.prepareToPlay()
   } catch let error {
       print(error.localizedDescription)
   }

} else {
    print("file not found")
}

我尝试过这样的网址:

let NoteUrl = Bundle.main.url(forResource: "Voice Note", withExtension: "m4a")

但是我无法播放.有人可以帮我按文件名播放m4a文件吗?任何帮助将不胜感激.

But I couldn't get it to play. Can someone help me to play m4a file by file's name? Any help will be appreciated.

推荐答案

您正在将Documents文件夹传递到音频播放器.您的代码需要将特定的文件名附加到Documents文件夹中.

You are passing the Documents folder to the audio player. Your code needs to append the specific filename to the Documents folder.

let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
let url = documentsURL.appendingPathComponent("Voice Note.m4a")
