当app在离子状态下处于非活动状态时，搜索信标背景

Question

我做了什么： - 嗨，当应用程序处于非活动状态时，我尝试在后台搜索信标，我也提到了一个链接＆＃34; nraboy / ng-cordova -beacon＃4 ＆＃34;

以下代码 startMonitoringForRegion 不会调用＆＃34; didEnterRegion ＆＃34;和＆＃34; didExitRegion ＆＃34;。

请帮助我如何进行背景搜索或监控

我的代码段： -

.controller("ExampleController", function($scope, $rootScope, $ionicPlatform, $cordovaBeacon) {
            console.log("start")
            console.log($cordovaBeacon)

    $scope.beacons = {};

    $ionicPlatform.ready(function() {

        $cordovaBeacon.requestAlwaysAuthorization();

        $rootScope.$on("$cordovaBeacon:didEnterRegion", function(event, pluginResult) {

            var uniqueBeaconKey;
            for(var i = 0; i < pluginResult.beacons.length; i++) {
                uniqueBeaconKey = pluginResult.beacons[i].uuid + ":" + pluginResult.beacons[i].major + ":" + pluginResult.beacons[i].minor;
                $scope.beacons[uniqueBeaconKey] = pluginResult.beacons[i];
                       console.log("ibeacon elements")
                       console.log(pluginResult.beacons)
            }
            $scope.$apply();
        });

         $rootScope.$on("$cordovaBeacon:didExitRegion", function(event, pluginResult) {
        console.log("ibeacondidExitRegion")
     // $cordovaVibration.vibrate(500);
            });
        $cordovaBeacon.startMonitoringForRegion($cordovaBeacon.createBeaconRegion("estimote", "uuid"));

       // 
    });
});

前景工作： -

我的代码段： -

.controller("ExampleController", function($scope, $rootScope, $ionicPlatform, $cordovaBeacon) {

    $scope.beacons = {};

    $ionicPlatform.ready(function() {

        $cordovaBeacon.requestWhenInUseAuthorization();

        $rootScope.$on("$cordovaBeacon:didRangeBeaconsInRegion", function(event, pluginResult) {
            var uniqueBeaconKey;
            for(var i = 0; i < pluginResult.beacons.length; i++) {
                uniqueBeaconKey = pluginResult.beacons[i].uuid + ":" + pluginResult.beacons[i].major + ":" + pluginResult.beacons[i].minor;
                $scope.beacons[uniqueBeaconKey] = pluginResult.beacons[i];
            }
            $scope.$apply();
        });

        $cordovaBeacon.startRangingBeaconsInRegion($cordovaBeacon.createBeaconRegion("estimote", "8A458198-34AE-11E6-AC61-9E71128CAE77"));

    });
});

我刚刚改变了＃34; startRangingBeaconsInRegion＆＃34; to＆＃34; startMonitoringForRegion＆＃34;
