iBeacon基站可以創建一個信號區域，當進入和離開該區域時，應用就會檢測到并發出通知。iBeacon類似一個熱點，只要進入它的信號區域，就可以獲取它發出的信息，而無需先連接上。

iBeacon是基于藍牙和定位的，如同藍牙廣播一樣發送信息，只有進入信號區域才能收到，所以iBeacon并沒放在CoreBluetooth中，而是在位置相關的CoreLocation里。但是使用時要開啟藍牙

iBeacon的使用

1.首先要在工程里的info.plist增加字段NSLocationAlwaysUsageDescription（這個是允許一直在后臺運行的）

2 .h文件

#import<UIKit/UIKit.h>#import<CoreLocation/CoreLocation.h>@interface ViewController : UIViewController<CLLocationManagerDelegate,>@PRoperty (strong, nonatomic) CLBeaconRegion *beacon1;//被掃描的iBeacon@property (strong, nonatomic) CLLocationManager * locationmanager;@end,,,

3 .m文件

#define BEACONUUID @"12334566-7173-4889-9579-954995439125"http://iBeacon的uuid可以換成自己設備的uuid- (void)viewDidLoad {[super viewDidLoad];self.locationmanager = [[CLLocationManager alloc] init];//初始化self.locationmanager.delegate = self;self.beacon1 = [[CLBeaconRegion alloc] initWithProximityUUID:[[NSUUID alloc] initWithUUIDString:BEACONUUID] identifier:@"media"];//初始化監測的iBeacon信息[self.locationmanager requestAlwaysAuthorization];//設置location是一直允許}- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status{if (status == kCLAuthorizationStatusAuthorizedAlways) {[self.locationmanager startMonitoringForRegion:self.beacon1];//開始MonitoringiBeacon}}//發現有iBeacon進入監測范圍-(void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region{[self.locationmanager startRangingBeaconsInRegion:self.beacon1];//開始RegionBeacons}//找的iBeacon后掃描它的信息- (void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region{//如果存在不是我們要監測的iBeacon那就停止掃描他if (![[region.proximityUUID UUIDString] isEqualToString:BEACONUUID]){[self.locationmanager stopMonitoringForRegion:region];[self.locationmanager stopRangingBeaconsInRegion:region];}//打印所有iBeacon的信息for (CLBeacon* beacon in beacons) {NSLog(@"rssi is :%ld",beacon.rssi);NSLog(@"beacon.proximity %ld",beacon.proximity);......}}
