Question

我已经和iBeacons玩了几个星期了，并且想知道是否有可能从同一个视图控制器监视两个信标。

例如，到目前为止，我已经创建了一个具有三个特定视图的应用程序，每个视图都对单独的信标作出反应，根据范围改变内容并触发音乐和视频等动态内容。所有这些视图都是相同的布局，所以我想知道我是否可以更改它，所以我有一个视图控制器根据我附近的信标改变内容，而不是必须更改视图。

这样更有意义，因为你只能监控一个意味着当segue触发并且新信标被监控时，如果你向第一个信标移动，当你进入时，它不会回到那个视图。第一个信标接近。

我确信有一种方法可以做到这一点，因为在美国的苹果商店使用信标触发促销等等，并且他们在没有问题的情况下依靠最近的信标。

#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>

@interface ExhibitsViewController : UIViewController <CLLocationManagerDelegate,UIScrollViewDelegate>
{
CLBeacon *beacon;
}

@property (strong, nonatomic) CLBeaconRegion *beaconRegion;
@property (strong, nonatomic) CLLocationManager *locationManager

@end

这是我头文件中定义beacon，beaconRegion和locationManager的代码。

                _rangeLabel.text = [NSString stringWithFormat:@"%f",beacon.accuracy];

            }
            else
            {

            }
        }

    }
}
}

这是我在实施文件中的代码，它是信标的范围。

Answer 1

是的，你可以。要做到这一点，你不必保留属性self.beaconRegion你只需创建任意多个并开始监视并开始测距，例如我就是这样做的：

// Reion 1

CLBeaconRegion *region = [[CLBeaconRegion alloc] initWithProximityUUID:uuid major:major minor:minor identifier:identifier];
region.notifyOnEntry = YES;
region.notifyOnExit = YES;
// launch app when display is turned on and inside region
region.notifyEntryStateOnDisplay = YES;

if ([CLLocationManager isMonitoringAvailableForClass:[CLBeaconRegion class]])
{
    [_locationManager startMonitoringForRegion:region];
    [_locationManager startRangingBeaconsInRegion:region];
}

// Region 2

   CLBeaconRegion *region2 = [[CLBeaconRegion alloc] initWithProximityUUID:uuid2 major:major2 minor:minor2 identifier:identifier2];
    region2.notifyOnEntry = YES;
    region2.notifyOnExit = YES;
    // launch app when display is turned on and inside region
    region2.notifyEntryStateOnDisplay = YES;

    if ([CLLocationManager isMonitoringAvailableForClass:[CLBeaconRegion class]])
    {
        [_locationManager startMonitoringForRegion:region2];
        [_locationManager startRangingBeaconsInRegion:region2];
    }

//等等

在每个self.locationManager委托方法之后，确保您拥有哪个信标，例如：

- (void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region {

    if ([region isKindOfClass:[CLBeaconRegion class]]) {
        CLBeaconRegion *beaconRegion = (CLBeaconRegion *)region;

        // Find out which beacon you have,
        // I check just UUID but maybe your beacons have the same uuid but major, minor are difference so you need to check minor/major as well
        if ([beaconRegion.proximityUUID isEqual:UUIDFIRST]) {

            //Do some stuff
        }
    }
}

如果您想查看哪个灯塔最近，请使用：

-(void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region

枚举信标数组：

if ([region isKindOfClass:[CLBeaconRegion class]]) {

        for (CLBeacon *beacon in beacons) { // 1
            // do the checking which beacon you have
            if ([beaconRegion.proximityUUID isEqual:UUIDFIRST]) { // 2

            }

                 // check beacon.accuracy property this should gives you distance in meters meters
                 //beacon.accuracy // 3
            }
        }
    }

//扩展

如果您在两个（或更多）信标范围内，信标将以信标数组传递给您。通过调用[beacons lastObject]，你只需要一个信标。您需要做的是枚举（遍及数组中的所有对象）在上面的代码中看到没有1（我编辑了一下）并看到你有什么信标（2）之后你比较距离（3）和价值较低的那个是最近的一个。

Answer 2

UUID可以在许多iBeacons上重复使用。每个信标都有一个主要数字和一个次要数字，以区分每个信标。

所以一家公司会购买一个UUID，但是（以商店为准），

所有专业= 1都在一楼：

未成年人1 =穿着女式服装
minor 2 =男装

少校2 =二楼：

minor 1 =童装
minor 2 =鞋

......等等。当应用程序在商店周围走动时，信标可以告诉它们在哪里，并根据数据提供广告/视频。

您在didRangeBeacons回调中检查这些值。我还相信一个应用程序可以同时监控多达20个区域，因此该回调中的region属性将包含不同的UUID

Answer 3

中提供的标识符

[[CLBeaconRegion alloc] initWithProximityUUID:iBeacon1uuid identifier:@"com.private.Gallery"];

对于您正在监控的每个信标，

必须不同。

在你的情况下，他们都是@“com.private.Gallery”
