Question

我正在尝试获取用户的纬度和经度。

import Foundation
import CoreLocation

class locationModule: NSObject, CLLocationManagerDelegate {
var locationManager = CLLocationManager()

func getLocation() {
    locationManager.delegate = self
    locationManager.requestAlwaysAuthorization()
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.startUpdatingLocation()
}

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    var location: CLLocationCoordinate2D = (manager.location?.coordinate)!
    print(location.latitude)
    print(location.longitude)
    }
}

这是代码在一个单独的Swift文件中，所以我需要getLocation()能够调用func locationManager，我如何从getLocation（）函数调用locationManager函数。

您的代码很好，但未被调用，可能是因为您没有将密钥添加到Info.plist中。

对于您的代码，请将NSLocationAlwaysUsageDescription添加到您的Info.plist中，其值为All your base are belong to us, so I use your location whenever I want.作为字符串值。然后就像func applicationDidBecomeActive(application: UIApplication)这样开始你的locationManager：

class AppDelegate：UIResponder，UIApplicationDelegate {

var window: UIWindow?
var locMod:locationModule?

func applicationDidBecomeActive(application: UIApplication) {
    if ( locMod == nil )
    {
       locMod = locationModule()
    }
    locMod?.getLocation()
}

第一次，您将看到提示，然后您将看到记录的位置。

仅供参考，这是我如何组织locationModule：

class locationModule: NSObject, CLLocationManagerDelegate {
    var locationManager = CLLocationManager()

    internal func getLocation() {
        locationManager.delegate = self
        locationManager.requestAlwaysAuthorization()
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.startUpdatingLocation()
    }


    // MARK : CLLocationManagerDelegate protocol
    @objc
    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        for location in locations {
            print("\(location.coordinate.latitude), \(location.coordinate.longitude)")
        }
    }
}

Swift：试图获取坐标，但不知道如何调用locationManager（）函数
