Question

我是快速编程的新手，我正在尝试开发app检测信标，但我仍然无法检测到任何信标。

let region = CLBeaconRegion(proximityUUID: NSUUID(UUIDString: "11111111-1111-1111-1111-111111111111")!,major: 1, minor: 1,  identifier: "MyBeacon")
locationManager.startMonitoringForRegion(region)
locationManager.startRangingBeaconsInRegion(region)

Answer 1

可以在前景和背景中检测到信标

步骤： - info.plist中的1个更改

在info.plist中，您需要更改“使用说明”。为此，添加带有您的消息的NSLocationAlwaysUsageDescription字符串类型。

步骤： - 2用于背景模式

在App Delegate中添加以下代码：

var window: UIWindow?
var locationManager:CLLocationManager = CLLocationManager()

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    locationManager.delegate = self
    locationManager.requestAlwaysAuthorization()
    // Request permission to send notifications
    let center = UNUserNotificationCenter.current()
    center.requestAuthorization(options:[.alert, .sound]) { (granted, error) in }
    return true
}

func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
    rangeBeacons()

}

func rangeBeacons(){
    let uuid = UUID(uuidString: "3e1d7817-4eac-4b27-b809-deee2f246c46")
    //let uuid = UUID(uuidString: "8492E75F-4FD6-469D-B132-043FE94921D8")
    let major:CLBeaconMajorValue = 1
    let minor:CLBeaconMinorValue = 2
    let identifier = "myBeacon"
    let region = CLBeaconRegion(proximityUUID: uuid!, major: major, minor: minor, identifier: identifier)
    region.notifyOnEntry = true
    region.notifyEntryStateOnDisplay = true
    region.notifyOnExit = true
    locationManager.startRangingBeacons(in: region)
    locationManager.startMonitoring(for: region)
}

func locationManager(_ manager: CLLocationManager, didEnterRegion region: CLRegion) {
    let content = UNMutableNotificationContent()
    content.title = "Hello!!!"
    content.body = "You Are Back in the Office"
    content.sound = .default()
    let request = UNNotificationRequest(identifier: "SufalamTech", content: content, trigger: nil)
    UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
}

func locationManager(_ manager: CLLocationManager, didExitRegion region: CLRegion) {
    let content = UNMutableNotificationContent()
    content.title = "Alert!!!"
    content.body = "You are Out of the Office"
    content.sound = .default()
    let request = UNNotificationRequest(identifier: "identifier", content: content, trigger: nil)
    UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
}

也不要忘记添加CLLocationManagerDelegate并导入CoreLocations和UserNotifications

步骤： - 3用于ForeGround或活动模式

在ViewController中添加以下代码

func locationManager(_ manager: CLLocationManager, didRangeBeacons beacons: [CLBeacon], in region: CLBeaconRegion) {
    guard let discoveredbeaconProximity = beacons.first?.proximity else {print("Beacons Cannot be located"); return }

    if ((discoveredbeaconProximity == .far) || (discoveredbeaconProximity == .near) || (discoveredbeaconProximity == .immediate)) {
        let alert = UIAlertController(title: "Alert", message: "You are in the Beacon Region", preferredStyle: UIAlertControllerStyle.alert)
        alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: nil))
        self.window?.rootViewController?.present(alert, animated: true, completion: nil)

    }
    if discoveredbeaconProximity == .unknown{
        let alert = UIAlertController(title: "Alert", message: "You are out of the Beacon Region!!!", preferredStyle: UIAlertControllerStyle.alert)
        alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: nil))
        self.window?.rootViewController?.present(alert, animated: true, completion: nil)

    }
}

注意： - 您需要更改信标UUID and Major and Minor值相应

Answer 2

SWIFT 3：

首先，您应该添加 CoreLocation.Framework

在.Plist文件中添加带有适当字符串的键/字符串NSLocationAlwaysUsageDescription
在您的对象中添加CLLocationManagerDelegate
在此示例中添加CLLocationManagerDelegate委托方法我将添加didRangeBeacons方法

func locationManager(_ manager: CLLocationManager, didRangeBeacons
beacons: [CLBeacon], in region: CLBeaconRegion) {
           print(beacons)   }

创建并初始化locationManager

var locationManager : CLLocationManager = CLLocationManager()

创建CLBeaconRegion

let beaconRegion : CLBeaconRegion = CLBeaconRegion(
    proximityUUID: NSUUID.init(uuidString:"****-****-****-****-******") as! UUID,
    identifier: "my beacon")

将代理人添加到对象locationManager.delegate = self
使用

locationManager.requestAlwaysAuthorization（）

现在让我们开始范围

  locationManager.startRangingBeacons(in: beaconRegion)

这将自动调用委托方法

   func locationManager(_ manager: CLLocationManager, didRangeBeacons beacons: [CLBeacon], in region: CLBeaconRegion) {
        print(beacons)

    }

注意：如果要监视beacon的进入/退出状态，则需要添加

locationManager.startMonitoring(for: beaconRegion)

最后：确保您的信标已打开并且您正在测试iBeacon Frame Enjoy：D

Answer 3

简单示例：

将NSLocationAlwaysUsageDescription添加到您的*.plist文件中。

在ViewController中创建locationManager和beaconRegion。设置locationManager委托，请求用户授权，然后开始监视/测距。

let locationManager : CLLocationManager = CLLocationManager()
let beaconRegion : CLBeaconRegion = CLBeaconRegion(
  proximityUUID: NSUUID.init(uuidString:"11111111-1111-1111-1111-111111111111") as! UUID,
  major: 1,
  minor: 1,
  identifier: "my beacon")

locationManager.delegate = self
locationManager.requestAlwaysAuthorization()
locationManager.startMonitoring(for: beaconRegion)

添加CLLocationManagerDelegate的扩展名：

extension ViewController : CLLocationManagerDelegate {
  func locationManager(manager: CLLocationManager, didRangeBeacons beacons: [CLBeacon], inRegion region: CLBeaconRegion) {
    print(beacons)
  }

  func locationManager(manager: CLLocationManager, didEnterRegion region: CLRegion) {
    let beaconRegion = region as! CLBeaconRegion
    print("Did enter region: " + (beaconRegion.major?.stringValue)!)
  }

  func locationManager(manager: CLLocationManager, didExitRegion region: CLRegion) {
    let beaconRegion = region as! CLBeaconRegion
    print("Did exit region: " + (beaconRegion.major?.stringValue)!)
  }
}

注意：激活蓝牙，检查您的设备上是否激活了位置服务（不支持模拟器），使用此区域，您只能找到具有此UUID + major + minor的信标。

一个简单的代码，用于检测swift中的任何信标
