：私は...場所が、私は、私は同じエラーを取得するアプリを実行するたびに使用する許可を

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)") 
    } 
} 

エラーを依頼する必要な機能を設定します

私はswift 3.0の新人ですが、私はこれを解決する方法について何かを見つけることができませんでした（私はstackoverflowでそれを見つけましたが、回答は私には役に立たなかった...）

Answer 1

xcode8とsw ift3では、代理メソッドはswiftからコピーされます。2.以下のように代理メソッドを変更します。

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)") 
     } 

    } 

}
