【问题描述】：
我已经在 iBeacons 上玩了几个星期了，如果可以从同一个视图控制器监视两个信标，我很想知道。
例如，到目前为止，我已经制作了一个具有三个单独视图的应用程序，每个视图都会对单独的信标做出反应，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，所以如果我可以更改它，我会很痛苦，所以我有一个视图控制器可以根据我附近的信标更改内容，而不必更改视图。
这会更有意义，因为您只能监视一个，这意味着当 segue 触发并且正在监视新信标时，如果您移回第一个信标，它不会在您进入第一个信标时返回该视图接近。
我确信有一种方法可以做到这一点，因为美国的苹果商店正在使用信标来触发促销等，并且他们没有问题地依赖最近的信标。
#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
这是我的头文件中定义信标、beaconRegion 和 locationManager 的代码。

这是我在测量信标的实现文件中的代码。
