javascript - Cordova 和 HTML5 在播放声音时的差异

Question

尝试在 iOS 设备/模拟器上以 HTML5 和 Cordova 播放声音时，得到不同的结果。它工作正常，并且在移动浏览器中运行 HTML5 时我总是有声音对象。 iOS 模拟器中未定义声音对象(因此我无法播放它)。

    SC.initialize({
        client_id: 'MYIDGOESHERE'
    });

    var soundCloudUrl = '';

    //Grab the artist detail and then grab the soundcloud details
    $http.post(BASE_URL + 'artistdetail', {band_id: band_id}).
        success(function (data, status, headers, config) {

            $scope.artistDetails = data;
            soundCloudUrl = "https://soundcloud.com/en-flux/jomox-rode-drop";
        }).
        error(function (data, status, headers, config) {
            $scope.showAlert("Oops", "Try again later.");
        }).then(function () {
            $http.get('http://api.soundcloud.com/resolve.json?url=' + soundCloudUrl + '&client_id=MYCLIENTID').
                success(function (data) {
                    console.log(data);
                    $scope.soundcloudData = data;
                    SC.stream(data.uri, function (sound) {
                        console.log(sound); //THIS IS THE LOG THAT DIFFERS
                        $scope.playTrack = function () {
                            sound.play();
                            $scope.playing = true;
                        }
                        $scope.pauseTrack = function () {
                            sound.pause();
                            $scope.playing = false;
                        }
                        $scope.leaveDetail = function (state) {
                            if (state == 'stop') {
                                sound.stop();
                            } else {
                                sound.pause();
                            }
                            $scope.playing = false;
                        }

                    });
                }).
                error(function (data, status, headers, config) {
                    // called asynchronously if an error occurs
                    // or server returns response with an error status.
                });

        });

所以，在 iOS 中，我对声音的 console.log 感到错误，但直接在浏览器中的 HTML5 中，一切都很好......有什么想法吗？

你的 promise 链很长。也许只是将其分解并逐步处理所有事情。你可能已经这样做了，但我知道随着我的锁链/回调 hell 开始增长，东西坏了，我必须回去追踪。

设置和初始化:

// Source to the Soundcloud channels I'm requesting
$scope.scdata = soundCloud.soundCloudData;

// Initialize the Soundcloud API onload of the controller
soundCloud.initialize();

// Currently not being used will be (didn't work when I declared it in         the promise)
$scope.player = null; 

获取 SC 特定信息的用户交互:

// Click in the element to get it's object and grab the SC id
$scope.load = function(){

  // Create the request url (/user + '-userID'/, /channels... )
  var url = '/tracks/' + this.m.id;

  // GET request to Soundcloud
  SC.stream(url).then(function(player){
    $scope.show();
    $scope.player = player;
  });
};

然后我为我的播放器创建了函数:

$scope.player.pause();
  $scope.player.play();
};

// Click play to load the track
$scope.play = function () {
  $scope.player.play();
};

// Click play to close the track
$scope.stop = function () {
  $scope.player.pause();
};

在我开始工作后，我重构了错误、成功消息......
