React-Native-Audio-Toolkit 准备失败

Question

我正在尝试使用 React-native-audio-toolkit 构建我自己的 Recorder/Player。

按照他们的文档，但我不确定如何正确准备记录。

（在 iOS 模拟器上）

这是我的代码

const fileName = 'test.mp4';
let recorder = new Recorder(fileName, {
  bitrate: 256000,
  channels: 2,
  sampleRate: 44100,
  quality: 'high',
}).prepare((err, fspath) => {
  if (err) {
    console.log('recorder prepare failed: ', err);
  } else if (!err) {
    props.onFileURIChange(fspath);
    console.log('fspath: ', fspath);
    recorder.record();
  }
});

错误是

recorder prepare failed:  {
    "err": "preparefail", "message": "Failed to prepare recorder. Settings are probably wrong.",
    "stackTrace": [
        "0   myapp                            0x000000010a2f61cf +[Helpers errObjWithCode:withMessage:] + 159",

    ]
}

注意：我尝试使用默认的 recorderOptions 但同样的错误:(

注意：这只发生在模拟器上。在真实设备上，它运行良好。 :)

你更新你的 info.plist 了吗？

如果没有，您可能需要添加以下行：

<key>NSMicrophoneUsageDescription</key>
<string>The description why you need to use microphone.</string>

或添加隐私-麦克风使用说明
