UILabel 上显示的纬度和经度

Question

您好，我只需要一些帮助来检索用户位置的纬度和经度，并能够将其显示在 UILabel 上。 我对 swift 很陌生，而且我知道如何接收这些值，因为我使用过 void 函数，但实际显示它们是让我感到兴奋的原因

谢谢

Answer 1

您可以使用核心位置来执行此操作，如下所示

1。提供适当的描述

要收集位置变化数据，您需要在 Info.plist 文件中设置两个特殊字符串



然后执行此操作

import CoreLocation

final class ViewController: UIViewController {

    @IBOutlet weak var coordinatesLabel: UILabel!

    let locationManager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()
        locationManager.requestAlwaysAuthorization()
        locationManager.delegate = self
    }

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        locationManager.startUpdatingLocation()
    }

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        locationManager.stopUpdatingLocation()
    }
}

extension ViewController: CLLocationManagerDelegate {
    func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
        guard status == .authorizedAlways || status == .authorizedWhenInUse else {
            // Handle when no access
            return
        }
        manager.startUpdatingLocation()
    }

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        guard let location = locations.first?.coordinate else { return }
        coordinatesLabel.text = "Lat: \(location.latitude), Lng: \(location.longitude)"
    }
}
