ngCordova 媒体插件异常

Question

我正在使用 ngCordova 尝试在 ionic 框架应用程序中录制音频。当我在装有 iOS 9.1 的 iPhone 6 上运行它时，代码正在运行但抛出以下消息：

异常 nativeEvalAndFetch : TypeError: undefined is not an object (evalating 'q.notify')

（是的，异常在错误中是这样拼写的）。

我的代码：

$scope.startRecording = function () {
     console.log("In Start Recording Method!")
     if (ionic.Platform.isIOS()) {
        console.log("It's iOS!");
        var d = new Date();
        var epochSeconds = d.getTime();
        var audioFileName = $scope.input.sectionName+epochSeconds;
        $scope.input.audioFileName = audioFileName;
        $scope.input.mediaSrc = "documents://"+ $scope.input.audioFileName + ".wav";
     } else if (ionic.Platform.isAndroid()) {
        console.log("It's Android!");
        var d = new Date();
        var epochSeconds = d.getTime();
        var audioFileName = $scope.input.sectionName+epochSeconds;
        $scope.input.audioFileName = audioFileName;
        $scope.input.mediaSrc = $scope.input.audioFileName + ".amr";
     }

    console.log("Setting media src to: " + $scope.input.mediaSrc)
    console.log("Creating media object.");
    $scope.input.disableStartRecord = true;
    $scope.input.disableStopRecord = false;
    var mediaObj = $cordovaMedia.newMedia($scope.input.mediaSrc,
          // success callback
        function() {
            console.log("recordAudio():Audio Success");
        },

        // error callback
        function(err) {
            console.log("recordAudio():Audio Error: "+ err.code);
        });

    $scope.mediaObj = mediaObj;

    console.log("Starting recording...");
    $scope.mediaObj.startRecord();
  }

  $scope.stopRecording = function () {
     console.log("Recording stopped to: " + $scope.input.audioFileName);
     $scope.input.disableStartRecord = true;
     $scope.input.disableStopRecord = true;
     $scope.mediaObj.stopRecord();
     $scope.mediaObj.release();
  }

Xcode 控制台中的输出：

有什么想法吗？

我切换到了 cordova-plugin-media-capture 插件，它完全按照我的需要工作，甚至提供了一个简单但足够好的用户界面来进行录制。基本sn-p：

      var options = { limit: 1, duration: 30 };
      $cordovaCapture.captureAudio(options).then(function(audioData) {
        console.log("Audio captured successfully!");
        // Success! Audio data is here
         var i, path, len;
          for (i = 0, len = audioData.length; i < len; i += 1) {
              path = audioData[i].fullPath;
              console.log("The recorded file is at: " + path);
              console.log("Moving file to data directory.")
              onAudioSuccess("file://"+path);

          }
       },fail}

所以...如果您想录制音频，请使用cordova capture。
