Ios startMonitoringSignificantLocationChanges不调用didUpdateLocations:当应用程序关闭时

Im使用IBeacon构建一个简单的ios应用程序，Im使用startMonitoringForRegion检测信标

好的

我还想在应用程序处于后台或关闭状态时检查用户位置，为此，我使用startMonitoringSignificantLocationChanges。在后台模式下工作正常，但当应用程序关闭时，不会触发didUpdateLocations:回调

我的代码（来自AppDelegate.m）如下：

    - (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];

        }
    }

有什么想法吗

谢谢

您等待此回调多长时间？我了解到startMonitoringSignificantLocationChanges仅在检测到设备相关基站的变化时才会发送新事件，从而减少更新频率并显著降低功耗。所以我在上班的时候检查它，大约5公里。“它不应该期望通知的频率超过每五分钟一次”-从docsThanks，但不是时间问题，我等了几个小时，没有发送通知。我添加了一些代码，我在didUpdateLocations:callback中触发了一个通知。当应用程序关闭时，didFinishLaunchingWithOptions:中的通知正在启动，但didUpdateLocations中的通知：否。
