一个简单的代码,用于检测swift中的任何信标

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

快速 3：

首先你应该添加CoreLocation.Framework

• 在 .Plist 文件中添加NSLocationAlwaysUsageDescription具有适当字符串的键/字符串

• 在您的对象中添加 CLLocationManagerDelegate

• CLLocationManagerDelegate在这个例子中添加 委托方法我将只添加 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")
  

• 将委托添加到您的对象 locationManager.delegate = self

• 向用户请求位置授权

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：如果你想监控信标的进入/退出状态，你需要添加

locationManager.startMonitoring(for: beaconRegion)

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

Answer 2

可以在前景和背景中检测信标

步骤: - 1.更改info.plist

在info.plist中,您需要更改"使用说明".为此,添加NSLocationAlwaysUsageDescription带有Message的String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和导入CoreLocations和UserNotifications

步骤: - 3用于ForeGround或活动模式

在ViewController中添加以下代码片段

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: - 您需要相应地更改您的信标UUID and Major and Minor值
