我想使用Swift获取当前的纬度和纬度,并通过标签显示.我试图这样做,但标签上没有显示.

import UIKit
    import CoreLocation
    class ViewController: UIViewController,CLLocationManagerDelegate{

    @IBOutlet weak var longitude: UILabel!
    @IBOutlet weak var latitude: UILabel!
    let locationManager = CLLocationManager()
    override func viewDidLoad() {
            super.viewDidLoad()
            if (CLLocationManager.locationServicesEnabled()) {
                        locationManager.delegate = self
                        locationManager.desiredAccuracy = kCLLocationAccuracyBest
                        locationManager.requestWhenInUseAuthorization()
                        locationManager.startUpdatingLocation()
                    } else {
                        println("Location services are not enabled");
                    }
                }
        // MARK: - CoreLocation Delegate Methods
            func locationManager(manager: CLLocationManager!,didFailWithError error: NSError!) {
                locationManager.stopUpdatingLocation()
                removeLoadingView()
                if ((error) != nil) {
                    print(error)
                }
            }

            func locationManager(manager: CLLocationManager!,didUpdateLocations locations: [AnyObject]!) {
                var locationArray = locations as NSArray
                var locationObj = locationArray.lastObject as CLLocation
                var coord = locationObj.coordinate
                longitude.text = coord.longitude
                latitude.text = coord.latitude
                longitude.text = "(coord.longitude)"
               latitude.text = "(coord.latitude)"
            }
    }

IMHO,当您正在查找的解决方案非常简单时,您的代码过于复杂.

我已经通过使用以下代码：

首先创建一个CLLocationManager和请求授权的实例

var locManager = CLLocationManager()
    locManager.requestWhenInUseAuthorization()

然后检查用户是否允许授权.

var currentLocation = CLLocation!

if( CLLocationManager.authorizationStatus() == CLAuthorizationStatus.AuthorizedWhenInUse ||
        CLLocationManager.authorizationStatus() == CLAuthorizationStatus.Authorized){

      currentLocation = locManager.location

}

使用它只是这样做

label1.text = "(currentLocation.coordinate.longitude)"
label2.text = "(currentLocation.coordinate.latitude)"

您将它们设置为label.text是正确的,但我可以想到的唯一原因是用户没有给您权限,这就是为什么您的当前位置数据将为零.

但是,您需要调试并告诉我们.
另外CLLocationManagerDelegate也是没有必要的.

希望这有帮助.如果有疑问,请问
