我试图在名为经度和纬度的2个标签上显示经度和纬度，但我没有任何结果。如何在标签上显示经度和纬度-swift
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
}
}
我在上longitude.text = coord.logitude错误，同样为它说，它不能转换为字符串第二个表。我是Swift新手。
