startMonitoringSignificantLocationChanges not calling didUpdateLocations: when app is closed - ios

Question

Im building a simple ios app with IBeacon, Im using startMonitoringForRegion for detect beacons.
Thats working ok.
I also want to check the users location when the app is background or closed, for that purpose im using startMonitoringSignificantLocationChanges. In background modes works ok, but when the app is closed the didUpdateLocations: callback is not fired.
My code (from AppDelegate.m) is below:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
if ([launchOptions objectForKey:UIApplicationLaunchOptionsLocationKey]) {
[self.locationManager startMonitoringSignificantLocationChanges];
NSString *message = #"UIApplicationLaunchOptionsLocationKey";
[self sendLocalNotificationWithMessage:message];
}
UILocalNotification *localNotif =
[launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (localNotif)
{
NSString *idN = [localNotif.userInfo objectForKey:#"id_notif"];
[self sendToDetail:idN];
}
if ([UIApplication instancesRespondToSelector:#selector(registerUserNotificationSettings:)]) {
NSLog(#"RESPONDS!!!!!");
[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeSound|UIUserNotificationTypeBadge categories:nil]];
}
[self resetBadge];
// Override point for customization after application launch.
NSUUID *beaconUUID = [[NSUUID alloc] initWithUUIDString:#"B9407F30-F5F8-466E-AFF9-25556B57FE6A"];
NSString *regionIdentifier = #"iBeacons region 1";
CLBeaconRegion *beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID: beaconUUID identifier: regionIdentifier ];
beaconRegion.notifyEntryStateOnDisplay = YES;
self.locationManager = [[CLLocationManager alloc]init];
if([self.locationManager respondsToSelector:#selector(requestAlwaysAuthorization)]){
[self.locationManager requestAlwaysAuthorization];
}
self.locationManager.delegate = self;
//self.locationManager.pausesLocationUpdatesAutomatically = NO;
[self.locationManager startMonitoringForRegion:beaconRegion];
return YES;
}
- (void) locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region{
[manager startRangingBeaconsInRegion:(CLBeaconRegion*) region];
NSLog(#"didEnterRegion");
}
- (void) locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region{
[manager stopRangingBeaconsInRegion:(CLBeaconRegion*) region];
NSLog(#"didExitRegion");
}
- (void)applicationDidEnterBackground:(UIApplication *)application {
NSLog(#"startMonitoringSignificantLocationChanges");
[self.locationManager startMonitoringSignificantLocationChanges];
}
- (void)applicationDidBecomeActive:(UIApplication *)application {
NSLog(#"stopMonitoringSignificantLocationChanges");
[self.locationManager stopMonitoringSignificantLocationChanges];
}
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations {
NSString *message = #"didUpdateLocations";
[self sendLocalNotificationWithMessage:message];
CLLocation *currentLocation = locations[0];
if (currentLocation != nil) {
NSString *longitude = [NSString stringWithFormat:#"%.8f", currentLocation.coordinate.longitude];
NSString *latitude = [NSString stringWithFormat:#"%.8f", currentLocation.coordinate.latitude];
NSString *message = [NSString stringWithFormat:#"longitud: %# latitud: %#", longitude,latitude ];
[self sendLocalNotificationWithMessage:message];
}
}
Any idea?
Thanks
