离子应用中的内存泄漏

Question

这是我的第一个离子应用程序。 我想我有一个内存泄漏问题，这是我的代码：

app.controller('ArtistsCtrl', ['$scope', '$cordovaGeolocation', '$ionicLoading', '$http', '$ionicPlatform', '$rootScope', 'UserService', '$timeout', function($scope, $cordovaGeolocation, $ionicLoading, $http, $ionicPlatform, $rootScope, UserService, $timeout) {

var posOptions = {timeout: 20000, enableHighAccuracy: true, maximumAge: 36000};

function gps(posOptions)
{
    $scope.searching = true;

    $cordovaGeolocation.getCurrentPosition(posOptions).then(function(position) {

        $scope.searching = false;

      //  var lat  = position.coords.latitude,
      //     long = position.coords.longitude;

        var lat  = 40.821216,
            long = -73.942684;

           console.log(lat, long);

        json_url = ('https://maps.googleapis.com/maps/api/geocode/json?latlng='+ lat +','+ long + '&key=123456789');

        $http.get(json_url).then(function(response) {
            // console.log(response.data);

            $ionicLoading.hide();

            $scope.address = response.data;

            var address_components = $scope.address.results[0].address_components,
                levels_arr = [];


            // United States
            for(var i = 0; i < address_components.length; i++){
                if(address_components[i].types[0] == 'locality'){
                    levels_arr.push(address_components[i]);
                }else if(address_components[i].types[0] == 'sublocality'){
                    levels_arr.push(address_components[i]);

                    console.log(address_components[i]);

                    var nyc = ['Bronx', 'Manhattan', 'Staten Island', 'Queens', 'Brooklyn'];

                    for(var i = 0; i < 5; i++){
                      if(inArray(address_components[i].long_name, nyc)){
                        levels_arr.push({long_name: "New York City", short_name: "New York City", types: ["locality"]});
                      }
                    }
                }

朋友开发，跟我谈过内存泄漏，我做了一些研究，但没有具体的...... 我无法找到它的位置..欢迎任何帮助，谢谢你们！
