Question

我是初学者，我只是为了好玩而学习Swift。现在我正在研究应用程序中地图的使用，我想将当前坐标（纬度，经度）打印到标签上。

现在，我已设法在地图上显示地图和当前位置并获取其坐标，但我需要帮助我如何将这些坐标打印到标签上。

这是我到目前为止所做的：

import UIKit
import MapKit
import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {

    @IBOutlet weak var posizione: UILabel!
    //Map
    @IBOutlet weak var map: MKMapView!



    @IBAction func rileva(_ sender: Any)
    {

    }


    let manager = CLLocationManager()

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation])
    {
        let location = locations[0]

        let span:MKCoordinateSpan = MKCoordinateSpanMake(0.01, 0.01)
        let myLocation: CLLocationCoordinate2D = CLLocationCoordinate2DMake(location.coordinate.latitude, location.coordinate.longitude)
        let region:MKCoordinateRegion = MKCoordinateRegionMake(myLocation, span)
        map.setRegion(region, animated: true)

        print(location.coordinate)
        print(location.altitude)

        self.map.showsUserLocation = true

    }

Answer 1

在didUpdateLocation功能中：

self.posizione.text = "latitude: " + String(location.coordinate.latitude) + ", longitude: " + String(location.coordinate.longitude)

Answer 2

嗨试试这段代码：

posizione.text = "latitude : \(location.coordinate.latitude) - longitude : \(location.coordinate.longitude)"

Answer 3

使用。

self.posizione.text = "Latitude is \(location.coordinate.latitute) and longitude is \(location.coordinate.longitude)".

将当前坐标打印到标签（Swift，Xcode8）
