【问题描述】：
我已经按照 Kontakt SDK 示例代码进行了信标搜索代码，如下所示。但是我的信标计数始终为 0，而我的 iPhone 附近有 11 个信标。任何人都可以帮助我解决这个问题吗？
我已经在 viewDidLoad 方法中初始化了 KTKBeaconManager，然后创建了区域对象并停止了任何以前的测距服务，然后开始了新的监控和测距服务。
它一直调用 didRangeBeacons 且信标计数 = 0。不确定到底是什么问题。它与他们的示例代码中的代码相同。
import UIKit
import KontaktSDK
class ViewController: UIViewController {
var beaconManager: KTKBeaconManager!
@IBOutlet var statusLabel: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
// Initiate Beacon Manager
beaconManager = KTKBeaconManager(delegate: self)
beaconManager.requestLocationAlwaysAuthorization()
// Region
let proximityUUID = NSUUID(uuidString: "f7826da6-4fa2-4e98-8024-bc5b71e0893e")
let region = KTKBeaconRegion(proximityUUID: proximityUUID! as UUID, identifier: "com.weenggs.KontaktDemo")
// Region Properties
region.notifyEntryStateOnDisplay = true
beaconManager.stopMonitoringForAllRegions()
// Start Ranging
beaconManager.startMonitoring(for: region)
beaconManager.startRangingBeacons(in: region)
beaconManager.requestState(for: region)
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
extension ViewController: KTKBeaconManagerDelegate {
func beaconManager(_ manager: KTKBeaconManager, didDetermineState state: CLRegionState, for region: KTKBeaconRegion) {
print("Did determine state \"\(state.rawValue)\" for region: \(region)")

}
func beaconManager(_ manager: KTKBeaconManager, didChangeLocationAuthorizationStatus status: CLAuthorizationStatus) {
print("Did change location authorization status to: \(status.rawValue)")

if let closestBeacon = beacons.sorted(by: { $0.0.accuracy < $0.1.accuracy }).first , closestBeacon.accuracy > 0 {
