带2个iPhone的双向iBeacon

Question

我一直在尝试在两台iOS设备之间设置“双向iBeacon通信”。我尝试使用This Technique on PubNub，我想我已设法启动发射器进行传输。但是，这两部手机都不匹配，如video所示。

由于我缺乏经验，本指南对我来说不太清楚，请查看我的代码。我收到的没有错误，两个iPhone上的项目工作正常，我可以看到Emitter正确传输，但是它们不匹配。

对于发射器和接收器，我已经导入了CoreLocation和CoreBluetooth框架，我通过单击“+”（未在源代码中编码）在info.plist中添加了“NSLocationAlwaysUsageDescription”和“NSLocationWhenInUseUsageDescription”。 / em>的

发射器代码：

class ViewController: UIViewController, CBPeripheralManagerDelegate {
var major = 9
var minor = 6
let uuid = NSUUID(UUIDString: "0CF052C2-97CA-407C-84F8-B62AAC4E9020")
var peripheralManager = CBPeripheralManager()
var advertisedData = NSDictionary()   
}

 override func viewDidLoad() {
    super.viewDidLoad()
let region = CLBeaconRegion(proximityUUID: uuid, major: 9, minor: 6, identifier: "com.yourcampany.example")
    self.advertisedData = region.peripheralDataWithMeasuredPower(nil)
    self.peripheralManager = CBPeripheralManager(delegate: self, queue: nil, options: nil)

func peripheralManagerDidUpdateState(peripheral: CBPeripheralManager!) {
    switch peripheral.state {
    case CBPeripheralManagerState.PoweredOn:
        self.peripheralManager.startAdvertising(advertisedData)
        self.powerON.text = "Power ON"
    default:
        break
    }
}

收件人代码：

class ViewController: UIViewController, CLLocationManagerDelegate {
   @IBOutlet var label: UILabel!

 var region = CLBeaconRegion()
var locationManager = CLLocationManager()
let uuid = NSUUID(UUIDString: "0CF052C2-97CA-407C-84F8-B62AAC4E9020")

override func viewDidLoad() {
    super.viewDidLoad()
 region = CLBeaconRegion(proximityUUID: uuid, identifier: "com.yourcampany.example")
    self.locationManager.delegate = self
    self.locationManager.requestAlwaysAuthorization()
    self.locationManager.startMonitoringForRegion(self.region)
 }

func locationManager(manager: CLLocationManager!, didRangeBeacons beacons: NSArray!, inRegion region: CLBeaconRegion!) {
    var beacon = beacons.lastObject as CLBeacon
    switch beacon.proximity {
    case CLProximity.Immediate:
       self.label.text = "Immediate"
    case CLProximity.Near:
        self.label.text = "Near"
    default:
       self.label.text = "AAA"
    }
}

我的Main.storyboard上的标签未设置为“立即”，“近”或“AAA”中的任何值。

另外，如果我想传输一个字符串（由5-6个字符组成），最合乎逻辑的方法是什么。我已经读过它不可能发送大块数据但是一串几个字符怎么样？ [可能使用 CentralManager 和 PeripheralManager ]

Answer 1

您尚未致电self.locationManager.startRangingBeaconsInRegion(self.region)。如果没有此调用，您将无法获得didRangeBeacons委托方法的回调。您拨打了self.locationManager.startMonitoringForRegion(self.region)，但这会调用didEnterRegion＆amp; didExitRegion委托方法。

所以你应该 -

override func viewDidLoad() {
    super.viewDidLoad()
 region = CLBeaconRegion(proximityUUID: uuid, identifier: "com.yourcampany.example")
    self.locationManager.delegate = self
    self.locationManager.requestAlwaysAuthorization()
    self.locationManager.startRangingBeaconsInRegion(self.region)
 }

您需要做的一件事是更改回调代码以操纵主线程上的UI。您必须像这样包装UI更改：

dispatch_async(dispatch_get_main_queue(),{
    switch beacon.proximity {
    case CLProximity.Immediate:
       self.label.text = "Immediate"
    case CLProximity.Near:
        self.label.text = "Near"
    default:
       self.label.text = "AAA"
    }
});
