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。

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。
答案 1 :(得分：3)
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：
少校2 =二楼：
......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
答案 2 :(得分：0)
中提供的标识符
[[CLBeaconRegion alloc] initWithProximityUUID:iBeacon1uuid identifier:@"com.private.Gallery"];
必须不同。
在你的情况下，他们都是@“com.private.Gallery”
