代表必须响应locationManager：didUpdateLocations swift eroor

Hy伙计们,
我正在使用 swift 3.0创建一个应用程序,但我很快遇到了一个问题.我设置必要的功能来请求使用位置的权限,但每次运行应用程序时都会出现同样的错误…

Viewcontroller.h

import UIKit
import MapKit

class ViewController: UIViewController {

    let locationManager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.requestWhenInUseAuthorization()
        locationManager.requestLocation()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // dispose of any resources that can be recreated.
    }


}

extension ViewController : CLLocationManagerDelegate {
    private func locationManager(manager: CLLocationManager,didChangeAuthorizationStatus status: CLAuthorizationStatus) {
        if status == .authorizedWhenInUse {
            locationManager.requestLocation()
        }
    }

    private func locationManager(manager: CLLocationManager,didUpdateLocations locations: [CLLocation]) {
        if locations.first != nil {
            print("location:: (location)")
        }
    }

    private func locationManager(manager: CLLocationManager,didFailWithError error: NSError) {
        print("error:: (error)")
    }
}

错误：

我是swift 3.0的新手,但是我找不到任何关于如何解决这个问题的事情(我在stackoverflow上查了一下但是他们给出的答案并没有帮助我…)

解决方法

您使用的是xcode8和swift3,但您的委托方法是从swift复制的.2.更改您的委托方法,如下所示.

extension ViewController : CLLocationManagerDelegate {

    func locationManager(_ manager: CLLocationManager,didFailWithError error: Error) {
         print("error:: \(error.localizedDescription)")
    }

    func locationManager(_ manager: CLLocationManager,didChangeAuthorization status: CLAuthorizationStatus) {
        if status == .authorizedWhenInUse {
            locationManager.requestLocation()
        }
    }

    func locationManager(_ manager: CLLocationManager,didUpdateLocations locations: [CLLocation]) {

        if locations.first != nil {
            print("location:: (location)")
        }

    }

}
