ios - 在参数 Swift 中传递当前位置

Question

我正在尝试在参数中传递当前用户位置以获得所需的结果。我在我的 viewDidLoad 方法中得到这样的当前位置:-

self.locationManager.requestAlwaysAuthorization()

self.locationManager.requestWhenInUseAuthorization()

if CLLocationManager.locationServicesEnabled() {
     locationManager.delegate = self
     locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
     locationManager.startUpdatingLocation()
 }

之后，我调用了 didUpdateLocations 方法来获取当前位置坐标，并创建了两个变量来存储当前位置。

var latitude: String = ""
var longitude: String = ""

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        guard let locValue: CLLocationCoordinate2D = manager.location?.coordinate else { return }
        print("locations = \(locValue.latitude) \(locValue.longitude)")
        self.latitude = "\(locValue.latitude)" ; self.longitude = "\(locValue.latitude)"
        print(self.latitude, self.longitude)
    }

但是当我试图在参数中传递我的当前位置时，我没有得到任何值。

let param: [String : Any] =
                                 ["lat": self.latitude,
                                  "lng": self.longitude,
                                  "truck_type": "2",
                                  "title": "home",
                                  "job_type": "Jobs"


                                 ]
    print(param)
    CommonUtils.showHudWithNoInteraction(show: true)

    Alamofire.request("api", method: .post, parameters: param, encoding: JSONEncoding.default, headers: nil).responseJSON { (response:DataResponse<Any>) in

        CommonUtils.showHudWithNoInteraction(show: false)
        switch(response.result) {
        case .success(_):
            if let json = response.result.value as? [String:Any] {
                print(json)

                DispatchQueue.main.async {
                    self.fleetOwnerTableView.reloadData()
                }
            }

            break

        case .failure(_):
            print("Error")
            break

        }
    }

我不知道我做错了什么。如何将当前位置传递给参数？

Answer 1

更新didUpdateLocations方法调用api并传递当前位置

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    if let location = locations.last {
        callAPI(location: location.coordinate)
    }
}

你的api调用方式

func callAPI(location:CLLocationCoordinate2D) {
    let param: [String : Any] =
        ["lat": "\(location.latitude)",
         "lng": "\(location.longitude)",
         "truck_type": "2",
         "title": "home",
         "job_type": "Jobs"
    ]
    //Alamofire.request
}
