$cordovaDialogs使用时遇到的问题

１：按照http://ngcordova.com/docs/plugins/dialogs/文档介绍进行安装使用：

 //标题栏
.controller('TitleCtrl', function($scope,$cordovaDialogs,$ionicHistory){
     $scope.wzhGoBack = function(){
           $ionicHistory.goBack();
     };

     $scope.wzhCloseApp = function(){
         $cordovaDialogs.confirm('您确定要退出系统?', '友情提示', ['确定','取消'])
             .then(function(buttonIndex) {
                 // no button = 0, 'OK' = 1, 'Cancel' = 2
                 if (buttonIndex == 1) {
                     ionic.Platform.exitApp();
                 }
             });
         $cordovaDialogs.beep(3);
     };
})

运行在手机上只显示了标题栏，下面的界面没有了，通过运行ionic serve在网页上报错信息如下：

ionic.bundle.js:21157 Error: [$injector:unpr] Unknown provider: $cordovaDialogsProvider <- $cordovaDialogs <- TitleCtrl

２：需要安装ngCordova

参照：http://ngcordova.com/docs/install/

（１）index.html

    <script src="lib/ngCordova/dist/ng-cordova.min.js"></script>
    <script src="cordova.js"></script>

（２）app.js

angular.module('starter',
    [
      'ionic',
      'starter.controllers',
      'starter.services',
      'ngCordova'
    ]
)
