找出statUpdatingLocation在Swift中是否处于活动状态

我有一个基于位置的应用程序在 swift中运行.我试图检测self.locationManager.startUpdatingLocation()当前是否处于活动状态.

我正在努力寻找如何做到这一点,我也无法在互联网上找到它.我相当肯定这很容易实现.我不想设置BOOL,因为它需要是全局的.

if CLLocationManager.locationServicesEnabled() && /* START UPDATE LOCATION GOES HERE */ {

        self.locationManager.delegate = self
        self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
        self.locationManager.requestAlwaysAuthorization()
        self.locationManager.startUpdatingLocation()

        //self.locationManager.startMonitoringSignificantLocationChanges()

        sender.setTitle("END DAY", forState: UIControlState.Normal)

    } else {


    }

我知道现在这是一个迟到的答案.但是,如果您想知道locationManager是否正在更新,这可能是一种解决方案.

您的应用中应该只有一个CLLocationManager实例.因此,创建单身人士是理想的选择.然后,您应该重写方法startUpdatingLocation和stopUpdatingLocation.

(斯威夫特3)

import CoreLocation

class LocationManager: CLLocationManager {
    var isUpdatingLocation = false

    static let shared = LocationManager()

    override func startUpdatingLocation() {
        super.startUpdatingLocation()

        isUpdatingLocation = true
    }

    override func stopUpdatingLocation() {
        super.stopUpdatingLocation()

        isUpdatingLocation = false
    }
}

用法：

if LocationManager.shared.isUpdatingLocation {
    print("Is currently updating location.")
  } else {
    print("Location updates have stopped.")
  }
