我写了下面的代码,这是我能想到的最基本的Swift 3代码,用来检查我的应用程序是否可以检测到iBeacon是否可用。 但是,didEnterRegion只在蓝色月亮中被激发一次。我可能在手机上运行了20次,而且它只发射了两次。问题似乎并不是灯塔本身,因为当我使用App Store中的应用程序时,它总是检测到我的iBeacon。任何想法为什么这个回调很少被调用? PS:我已经添加了隐私 - 位置始终使用情况说明到Info.plist中didEnterRegion有时只被解雇
import UIKit
import CoreLocation
class ViewController: UIViewController {
let locationManager = CLLocationManager()
@IBOutlet weak var textLabel: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
locationManager.requestAlwaysAuthorization()
locationManager.delegate = self
// 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.
}
@IBAction func startMonitoring(_ sender: Any) {
if let uuid = UUID(uuidString: "10F86430-1346-11E4-9191-0800200C9A66") {
let beaconRegion = CLBeaconRegion(proximityUUID: uuid, major: 1, minor: 1,identifier: "iBeacon")
locationManager.startMonitoring(for: beaconRegion)
textLabel.text = "Monitoring"
}
}
}
extension ViewController: CLLocationManagerDelegate {
func locationManager(_ manager: CLLocationManager, monitoringDidFailFor region: CLRegion?, withError error: Error) {
textLabel.text = "\(error.localizedDescription)"
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
textLabel.text = "\(error.localizedDescription)"
}
func locationManager(_ manager: CLLocationManager, didEnterRegion region: CLRegion) {
textLabel.text = "Found a new beacon"
}
}
这是最可能的解释。 – davidgyoung
