IOS background problem

[Dionysios]

Hi,
I have a small project which requires ibeacons ranging in the foreground and monitoring with local notifications on the background. The plugin works great on Android but on IOS once I put the app on the background nothing happens. I looked the issue #53 but no luck.
Here is the code. Any help is appreciated. Thanks in advance!

app.startScanForBeacons = function() {
console.log('startScanForBeacons');

var delegate = new locationManager.Delegate();

delegate.didStartMonitoringForRegion = function(pluginResult){
console.log('Call monitoring');
app.didBeaconsInRegion(pluginResult);
};

// Called when monitoring and the state of a region changes.
// (Not used in this example, included as a reference.)
delegate.didDetermineStateForRegion = function(pluginResult){
//console.log('didDetermineStateForRegion: ' + JSON.stringify(pluginResult))
};

delegate.didStartRangingBeaconsInRegion = function(pluginResult){
console.log('didDetermineStateForRegion: ' + JSON.stringify(pluginResult))
};

delegate.didRangeBeaconsInRegion = function(pluginResult){
console.log('didDetermineStateForRegion: ' + JSON.stringify(pluginResult))
// app.didBeaconsInRegion(pluginResult);
};

// Set the delegare object to use.
locationManager.setDelegate(delegate)
// Request permission from user to access location info.
// This is needed on iOS 8.
locationManager.requestAlwaysAuthorization();

// Start monitoring and ranging our beacons.
for (var r in app.beaconRegions) {
var region = app.beaconRegions[r]

var beaconRegion = new locationManager.BeaconRegion(
region.id, region.uuid, region.major, region.minor)

// Start monitoring.
locationManager.startMonitoringForRegion(beaconRegion)
.fail(console.error)
.done()

// Start ranging.
locationManager.startRangingBeaconsInRegion(beaconRegion)
.fail(console.error)
.done()

}
}
// Display pages depending of which beacon is close.
app.didBeaconsInRegion = function(pluginResult) {

i have the same problem

[zefman]

Any solutions? I would love to use this plugin for a new project I have coming up but if this isn't working its a bit of a deal breaker for me.

i got a notification when app is colsed today but still testing
I have de.appplant.cordova.plugin.local-notification
and com.unarin.cordova.beacon installed
looks like this
var app = (function()

[
    // Estimote Beacon factory UUID.

var beacons = {};

// Timer that displays list of beacons.
var updateTimer = null;

app.initialize = function()
{
    document.addEventListener('deviceready', onDeviceReady, false);
};

function onDeviceReady()
{
    // Specify a shortcut for the location manager holding the iBeacon functions.
    window.locationManager = cordova.plugins.locationManager;

    // Start tracking beacons!
    startMonitoring();

    // Display refresh timer.
    //updateTimer = setInterval(displayBeaconList, 500);
}

function startMonitoring()
{

    window.plugin.notification.local.cancelAll();
    //window.plugin.notification.local.add({ message: 'startScanForBeacons' });

    var createLocalNotification = function (message) {
        window.plugin.notification.local.add({

I added these lines
var notifyEntryStateOnDisplay = true;
var beaconRegion = new cordova.plugins.locationManager.BeaconRegion(identifier, uuid, major, minor, notifyEntryStateOnDisplay);

and change testing device from an ipad mini to an iphone 5 and it started working for me.
If you still have problems go through #53

Hi,
i have some questions:

1. is it possible do notify only if the app is closed or runs in background?
2. I want to notify the user only one time ('please open the app') if he enters a region of a single beacon the first time. If the app is running he should not be notified.
3. How can i check the distance to the beacon if the app runs in background in didEnterRegion function, so that i can say if entered a beaconregion and the distance to the beacon is closer than 4meter, createLocalNotification

like

delegate.didEnterRegion = function(pluginResult) {
if (app runs in background mode && beacon.distance < 4meter && userisnotalreadynotified == false){
createLocalNotification('didEnterRegion: ' + JSON.stringify(pluginResult))

   var userisnotalreadynotified = true

}
};

does someone maybe have a codesnippet for that?

greez & thx 4 help Sebastian

Setting up the iBeacon regions like this didn't change a thing

new cordova.plugins.locationManager.BeaconRegion(identifier, uuid, major, minor, true);
