我目前正在使用ngCordova和Ionic构建iOS应用。部分规范包括能够访问/播放存储在应用程序'www'文件夹中的mp3文件。 经过实验,我可以从外部URL播放音乐文件,但是当我尝试使用本地存储的mp3时,我遇到了问题。
这是HTML:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">
<title></title>
<link href="lib/ionic/css/ionic.css" rel="stylesheet">
<link href="css/style.css" rel="stylesheet">
<script src="lib/ionic/js/ionic.bundle.js"></script>
<script src="js/ng-cordova.min.js"></script>
<script src="cordova.js"></script>
<script src="js/app.js"></script>
</head>
<body ng-app="editor">
<ion-pane>
<ion-header-bar class="bar-stable">
<h1 class="title">Editor</h1>
</ion-header-bar>
<ion-content ng-controller="MusicController">
<button class="button" ng-click="play('www/elvis.mp3')">Play</button>
</ion-content>
</ion-pane>
</body>
</html>
这是控制器/应用程序:
var editorApp = angular.module('editor', ['ionic', 'ngCordova'])
.run(function($ionicPlatform) {
$ionicPlatform.ready(function() {
// Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
// for form inputs)
if(window.cordova && window.cordova.plugins.Keyboard) {
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
}
if(window.StatusBar) {
StatusBar.styleDefault();
}
});
})
editorApp.controller("MusicController", function($scope, $cordovaMedia) {
$scope.play = function(src) {
var filePath = cordova.file.applicationDirectory + src;
var iOSPlayOptions = {
numberOfLoops: 2,
playAudioWhenScreenIsLocked : false
};
var media = $cordovaMedia.newMedia(filePath);
media.play(iOSPlayOptions);
};
});
当我“cordova build ios”并在xCode的手机上运行时,我收到以下错误:
2015-04-23 11:59:43.619 IonicProject [1487:375698]资源未知 '文件:///private/var/mobile/Containers/Bundle/Application/FB22B00F-9020-46C9-BBA2-674009BD84F7/IonicProject.app/www/elvis.mp3'
答案 0 :(得分:1)
您可以在离子中使用iOS应用的直接音频标签,而无需执行这些操作(这些是Android应用程序所必需的)。只需编写以下代码:
HTML代码
<div ng-bind-html="audioCall()"></div>
控制器代码
$scope.audioCall = function () {
if ($scope.audioUrl) {
return $sce.trustAsHtml("<audio controls> <source src='" + $scope.audioUrl + "' type='audio/mpeg'/></audio>");
} else {
return "";
}
};
