测试 iBeacons

首先，你必须请求授权位置服务

let locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.requestWhenInUseAuthorization()
// OR locationManager.requestAlwaysAuthorization()

然后你可以在 didRangeBeacons 里面获取所有 iBeacons 的信息

func locationManager(manager: CLLocationManager, didRangeBeacons beacons: [CLBeacon], inRegion region: CLBeaconRegion) {
    for beacon in beacons {
        print(beacon.major)
        print(beacon.minor)
    }
}
