错误域= kCLErrorDomain代码= 2“操作无法完成。 （kCLErrorDomain错误2。）“ [英] Error Domain=kCLErrorDomain Code=2 "The operation couldn’t be completed. (kCLErrorDomain error 2.)"

问题描述

import UIKit
import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {

    @IBOutlet var latLabel: UILabel!
    @IBOutlet var longLabel: UILabel!

    @IBOutlet var courseLabel: UILabel!
    @IBOutlet var speedLabel: UILabel!
    @IBOutlet var altLabel: UILabel!
    @IBOutlet var addressLabel: UILabel!

    var manager:CLLocationManager!
    var userLocation:CLLocation = CLLocation()

    override func viewDidLoad() {
        super.viewDidLoad()

        manager = CLLocationManager()
        manager.delegate = self
        manager.desiredAccuracy = kCLLocationAccuracyBest
        manager.requestWhenInUseAuthorization()
        manager.distanceFilter = 50
        manager.startUpdatingLocation()


    }

    func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {

        userLocation = locations[0] as CLLocation
        println(userLocation.coordinate.latitude)

        var latitude:CLLocationDegrees = userLocation.coordinate.latitude
        latLabel.text = "\(latitude)"
        var longitude:CLLocationDegrees = userLocation.coordinate.longitude
        longLabel.text = "\(longitude)"

        var course:CLLocationDirection = userLocation.course
        courseLabel.text = "\(course)"

        var speed:CLLocationSpeed = userLocation.speed
        speedLabel.text = "\(speed)"

        var altitude:CLLocationAccuracy = userLocation.altitude
        altLabel.text = "\(altitude)"


        CLGeocoder().reverseGeocodeLocation(userLocation, completionHandler: { (placemarks, error) -> Void in

            if (error != nil) {

                println(error)

            } else {
                if let p = CLPlacemark(placemark: placemarks?[0] as CLPlacemark) {
                    println(p)
                }
            }

        })



        //println("Location = \(locations)")
        println(locations)
    }


}

我一直收到此错误错误域= kCLErrorDomain Code = 2操作无法完成。（kCLErrorDomain error 2 。）当我试图获得用户最近的地址时。我不确定问题是什么，有人能看到发生了什么吗？谢谢。

I keep getting this error Error Domain=kCLErrorDomain Code=2 "The operation couldn’t be completed. (kCLErrorDomain error 2.)" when I try to get the users closest address. I am not sure what the issue is, can anybody see what is going on? Thanks.

推荐答案

这是一个网络错误，CLGeocoder需要一个有效的网络连接才能反转地理位置，根据文档。

That's a network error, CLGeocoder needs a working network connection in order to reverse geocode a location, according to the docs.

此外，CLGeocoder会限制地理编码请求，如果超出请求率则返回相同的错误，这也在类引用中记录。

Also, CLGeocoder will throttle geocoding requests, returning that same error if you exceed the request rate, this is also documented in the class reference.
