Kontakt信标和iOS:DidStartMonitoring for Region未按预期工作

我开始在iOS上使用Kontakt.io beacons，但即使我按照上的说明和上描述的第一步操作，似乎也只能让它工作一次

以下是我的ViewController代码：

#import "ViewController.h"
#import <KontaktSDK/KontaktSDK.h>

@interface ViewController () <KTKBeaconManagerDelegate>

@property KTKBeaconManager *beaconManager;
@property KTKBeaconRegion *region1;

@end

@implementation ViewController


- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    self.beaconManager = [[KTKBeaconManager alloc] initWithDelegate:self];
    NSUUID *myProximityUUID = [[NSUUID alloc] initWithUUIDString:@"xxxxxxxxx...xxxx"];
    _region1 = [[KTKBeaconRegion alloc] initWithProximityUUID:myProximityUUID identifier:@"Beacon_1"];

    switch ([KTKBeaconManager locationAuthorizationStatus]) {
        case kCLAuthorizationStatusNotDetermined:
            [self.beaconManager requestLocationAlwaysAuthorization];
            break;

        case kCLAuthorizationStatusDenied:
        case kCLAuthorizationStatusRestricted:
            // No access to Location Services
            break;

        case kCLAuthorizationStatusAuthorizedWhenInUse:
            // For most iBeacon-based app this type of
            // permission is not adequate
            break;

        case kCLAuthorizationStatusAuthorizedAlways:
            // We will use this later
            if ([KTKBeaconManager isMonitoringAvailable]) {
                [self.beaconManager startMonitoringForRegion:_region1];
            }
            break;
    }
}


- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (void)beaconManager:(KTKBeaconManager *)manager didChangeLocationAuthorizationStatus:(CLAuthorizationStatus)status {
    if (status == kCLAuthorizationStatusAuthorizedAlways) {
        _TheLabel.text = @"YEAH";
        if ([KTKBeaconManager isMonitoringAvailable]) {
            _TheLabel.text = @"YEAH!!!";
            [self.beaconManager startMonitoringForRegion:_region1];
        }
        // When status changes to kCLAuthorizationStatusAuthorizedAlways
        // e.g. after calling [self.beaconManager requestLocationAlwaysAuthorization]
        // we can start region monitoring from here
    }
}

//
- (void)beaconManager:(KTKBeaconManager *)manager didStartMonitoringForRegion:(__kindof KTKBeaconRegion *)region {
    // Do something when monitoring for a particular
    // region is successfully initiated
    _MonitoringStatus.text = @"Success";
    [manager startRangingBeaconsInRegion:region];
}

- (void)beaconManager:(KTKBeaconManager *)manager monitoringDidFailForRegion:(__kindof KTKBeaconRegion *)region withError:(NSError *)error {
    // Handle monitoring failing to start for your region
    _MonitoringStatus.text = @"FAIL!";
}

- (void)beaconManager:(KTKBeaconManager *)manager didEnterRegion:(__kindof KTKBeaconRegion *)region {
    // Decide what to do when a user enters a range of your region; usually used
    // for triggering a local notification and/or starting a beacon ranging
    [manager startRangingBeaconsInRegion:region];
    _OnRegionStatus.text = @"We're in!";
}

- (void)beaconManager:(KTKBeaconManager *)manager didExitRegion:(__kindof KTKBeaconRegion *)region {
    // Decide what to do when a user exits a range of your region; usually used
    // for triggering a local notification and stoping a beacon ranging
    [manager stopRangingBeaconsInRegion:region];
    _OnRegionStatus.text = @"We're out";
}

- (void)beaconManager:(KTKBeaconManager *)manager didRangeBeacons:(NSArray<CLBeacon *> *)beacons inRegion:(__kindof KTKBeaconRegion *)region {
    for(CLBeacon *beacon in beacons){
        _TheLabel.text = [NSString stringWithFormat:@"WOW! %ld", (long)[beacon proximity]];
    }
}

@end

这一次的效果与预期相符。但我对这种行为有点困惑。即使在强制关闭的情况下，该应用程序仍能对该区域进行监控？提前谢谢

据我所知，Kontakt.io的SDK基于苹果的核心位置，因此以下内容也适用：

在iOS中，与您的应用程序关联的区域会一直被跟踪， 包括应用程序未运行时。-

case kCLAuthorizationStatusAuthorizedAlways:
            // We will use this later
            if ([KTKBeaconManager isMonitoringAvailable]) {
                if([[self.beaconManager monitoredRegions] count] == 0) [self.beaconManager startMonitoringForRegion:_region1];
                else for(KTKBeaconRegion *reg in [self.beaconManager monitoredRegions]){
                    [self.beaconManager startRangingBeaconsInRegion:reg];
                }
            }
            break;
