iBeacon是苹果公司提出的“一种可以让附近手持电子设备检测到的一种新的低功耗、低成本信号传送器”的一套可用于室内定位系统的协议。 这种技术可以使一个智能手机或其他装置在一个iBeacon基站的感应范围内执行相应的命令
1、初始化CLLocationManager和CLBeaconRegion
let locationManager = CLLocationManager()
let beaconRegion: CLBeaconRegion = {
let region = CLBeaconRegion(proximityUUID: NSUUID(UUIDString: "7B1C1C64-077E-4D23-9F49-7E644A13B5A9")!, identifier: "7B1C1C64-077E-4D23-9F49-7E644A13B5A9")
region.notifyEntryStateOnDisplay = true
return region
}()
2、开始扫描
func start() {
stop()
locationManager.delegate = self
locationManager.startRangingBeaconsInRegion(beaconRegion)
}
3、实现CLLocationManagerDelegate代理方法
打印授权状态
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
if status == .AuthorizedAlways {
print("Location Access (Always) granted!")
} else if status == .AuthorizedWhenInUse {
print("Location Access (When In Use) granted!")
} else if status == .Denied || status == .Restricted {
print("Location Access (When In Use) denied!")
}
}
扫描到设备，accuracy实际距离
func locationManager(manager: CLLocationManager, didRangeBeacons beacons: [CLBeacon], inRegion region: CLBeaconRegion) {
print(">>>发现设备: becons: \(beacons)")
print("------------------------------")
for bc in beacons {
print (bc.accuracy)
}
}
4、停止扫描
func stop() {
locationManager.stopRangingBeaconsInRegion(beaconRegion)
locationManager.delegate = nil
}
