swift mapkit当前位置

Question

我正在使用<?php if (isset($_POST['mail-submit'])) { $hour = trim($_POST['mail-hour']); $phone = trim($_POST['mail-phone']); $email = trim($_POST['mail-email']); $message = trim($_POST['mail-msg']); if($hour != null && $phone != null && $email != null){ if(!filter_var($email, FILTER_VALIDATE_EMAIL)) { $signal = 'bad'; $msg = 'Invalid email. Please check'; } else { $signal = 'ok'; $msg = 'Form submitted'; } } else{ $signal = 'bad'; $msg = 'Please fill in all the fields.'; } $data = array( 'signal' => $signal, 'res-msg' => $msg ); echo json_encode($data); } ?> 来获取当前位置，但是却一直没有获取位置

尝试import CoreLocation，在mLocation中呼叫viewDidLoad。 完成mLocation功能后，LocationManager会更新您的位置。

if distance方法现在每100米更新一次。

import UIKit
import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {

    let myLocation = CLLocation()
    let locationManager = CLLocationManager()

    @IBOutlet weak var latitudeTextField: UITextField!
    @IBOutlet weak var longtitudeTextField: UITextField!

    override func viewDidLoad(){
        super.viewDidLoad()
        mLocation()
    }

    @IBAction func saveCurrentLocation(){
        self.latitudeTextField.text = "\\(myLocation.coordinate.latitude)"
        self.longtitudeTextField.text = "\(myLocation.coordinate.longitude)"

    }

    func mLocation(){
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.requestWhenInUseAuthorization()

        if CLLocationManager.locationServicesEnabled(){
            locationManager.startUpdatingLocation()
        }
    }

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations:[CLLocation]){
        let newLocation = locations[0]
        let distance = myLocation.distance(from: newLocation)
        if distance > 100 {
            myLocation = newLocation
        }
    }
}
