        set :function(key,value){
          $window.localStorage[key]=value;
        },        //读取单个属性
        get:function(key,defaultValue){
          return  $window.localStorage[key] || defaultValue;
        },        //存储对象，以JSON格式存储
        setObject:function(key,value){
          $window.localStorage[key]=JSON.stringify(value);
        },        //读取对象
        getObject: function (key) {

.controller('loginController',function($scope, $ionicPopup, $state,locals){

使用存储或读取方法
