iBeacon是iOS7的新增的功能,通过BLE实现室内定位,精确到厘米级别。
测试使用两台iPhone(支持BLE),一台作为iBeacon基站广播信号,代码使用官方源码AirLocate,另外一台作为接收端,直接使用的是App Store下载的AirLocate)。
1、广播端主要代码
NSDictionary *peripheralData = nil; region = [[CLBeaconRegion alloc] initWithProximityUUID:self.uuid major:[self.major shortValue]
minor:[self.minor shortValue] identifier:BeaconIdentifier]; peripheralData = [region peripheralDataWithMeasuredPower:power]; // The region's peripheral data contains the CoreBluetooth-specific data we need to advertise. if(peripheralData) {
//开始广播
[peripheralManager startAdvertising:peripheralData];
}
2、接收端主要代码
self.locationManager = [[CLLocationManager alloc] init]; self.locationManager.delegate = self; //接收端的uuid数组需要包含广播端的uuid for (NSUUID *uuid in [APLDefaults sharedDefaults].supportedProximityUUIDs) { CLBeaconRegion *region = [[CLBeaconRegion alloc] initWithProximityUUID:uuid identifier:[uuid UUIDString]]; self.rangedRegions[region] = [NSArray array]; } for (CLBeaconRegion *region in self.rangedRegions) { [self.locationManager startRangingBeaconsInRegion:region]; }
