ios - Local Notification 什么时候EnterRegion？

Question

我有以下代码，在应用程序终止时可以完美运行。

-(void)beaconManager:(id)manager didEnterRegion:(CLBeaconRegion *)region{


    UILocalNotification *notification = [UILocalNotification new];
    notification.alertBody = @"TEST NOTIFICATION";
    notification.soundName = UILocalNotificationDefaultSoundName;
    [[UIApplication sharedApplication] presentLocalNotificationNow:notification];

} 

但是当我执行以下操作时:

-(void) createTestNotification {

    UILocalNotification *notification = [UILocalNotification new];
    notification.alertBody = @"TEST";
    notification.soundName = UILocalNotificationDefaultSoundName;

    [[UIApplication sharedApplication] presentLocalNotificationNow:notification];

}
-(void)beaconManager:(id)manager didEnterRegion:(CLBeaconRegion *)region{


        [self createTestNotification];

}

它不起作用？我只是将我的代码移到外面没有别的吗？我知道当 didEnterRegion 被调用时，应用程序只有 5 秒，但调用此方法不会花费这个时间？

更新 1:

我刚发现地区 didEnterRegion返回的是我开始监控的那个，而不是属于应用刚刚看到的beacon的那个。我打算使用这个区域获取我的自定义消息取决于该地区的ma​​jor&minor。

但在我的情况下这是不可能的，所以我在 didEnterRegion 时开始测距接到电话，然后在didRangeBeacons它返回 beacons 数组我从 localDataBase "depend on Major&minor" 得到了属于这个 beacon 的文本消息

这是我的代码: 此代码在应用程序后台运行时有效并收到通知，但当应用程序关闭时永远不会收到通知？

-(void)beaconManager:(id)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region{

   [self handelBeaconsNotification:beacons];

}

-(NSString *) getBeaconFromLocalData:(NSNumber *)regionMajor andRegionMin:(NSNumber *)regionMinor{


    PFQuery *query = [PFQuery queryWithClassName:@"Beacons"];
    NSArray *allRegions_id = [[NSArray alloc] initWithObjects:[NSNumber numberWithInt:1], nil];
    [query whereKey:@"region_id" containedIn:allRegions_id];
    NSLog(@"%@",regionMajor);
    NSLog(@"%@",regionMinor);
    [query whereKey:@"major" equalTo:regionMajor];

    [query whereKey:@"minor" equalTo:regionMinor];

    [query fromLocalDatastore];

    NSArray *data = [query findObjects];

    return [[data objectAtIndex:0] valueForKey:@"enter_message"];





}

-(void) handelBeaconsNotification:(NSArray *)beaconsArray{


    for (int i = 0 ; i<beaconsArray.count; i++) {

        NSString *currentBeaconKey = [NSString stringWithFormat:@"%@-%@",[beaconsArray[i] major],[beaconsArray[i] minor]];

        if ([beaconsDictionary valueForKey:currentBeaconKey] == nil) {

            NSMutableDictionary *dateDic = [[NSMutableDictionary alloc] init];

            [dateDic setValue:[NSDate date] forKey:@"StartVisit"];

            [dateDic setValue:nil forKey:@"EndVisit"];

            [beaconsDictionary setValue:dateDic forKey:currentBeaconKey];

            UILocalNotification *notification = [UILocalNotification new];
            notification.alertBody = [self getBeaconFromLocalData:[beaconsArray[i] major] andRegionMin:[beaconsArray[i] minor]];
            notification.soundName = UILocalNotificationDefaultSoundName;
            notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:2];
            notification.timeZone = [NSTimeZone defaultTimeZone];
            [[UIApplication sharedApplication] scheduleLocalNotification:notification];

        }
    }

}

更新 2:我只是将 Log 添加到 didEnterRegion和 didRangeBeacons发现只有来自 didEnterRegion 的 NSLog然后应用程序看起来像它崩溃 和来自 didRangeBeacons 的日志没有出现
