Corelocation ist null und App-Abstürze beim Start

Question

Dieser Crash-Protokoll ist, dass ich bekommen von Crashlytics

Ich benutze CLLocationmanage r in AppDelegate, um Benutzer-Standort zu erhalten, wenn App für Standortaktualisierungen wacht.

import UIKit 
import FBSDKCoreKit 
import FBSDKLoginKit 
import Quickblox 
import Fabric 
import Crashlytics 
import CoreLocation 

@UIApplicationMain 
class AppDelegate: UIResponder, UIApplicationDelegate, CLLocationManagerDelegate { 

    var window: UIWindow? 
    var locationManager: CLLocationManager! 

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { 


      if var options = launchOptions { 

       if var _: NSNumber = options[UIApplicationLaunchOptionsLocationKey] as? NSNumber { 

        locationManager.startUpdatingLocation() 

       } 
      } 

     initLocationManager() 


     return true 
    } 

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

      if let lat = manager.location?.coordinate.latitude, 
       let long = manager.location?.coordinate.longitude { 

       //sends to server to update 
       updateloc(String(lat), long: String(long)) 
      } 

     } 


    func initLocationManager() { 
      if (nil == locationManager) { 
       locationManager = CLLocationManager() 
      } 
      locationManager.delegate = self 
      locationManager.desiredAccuracy = kCLLocationAccuracyBest 
      if #available(iOS 9.0, *) { 
       locationManager.allowsBackgroundLocationUpdates = true 
      } 

      let status = CLLocationManager.authorizationStatus() 
      if (status == CLAuthorizationStatus.AuthorizedAlways || status == CLAuthorizationStatus.AuthorizedWhenInUse) { 
       locationManager.startUpdatingLocation() 
      } 

     } 

Kann mir bitte jemand helfen?

Danke.

Answer 1

Sie müssen initLocationManager() anrufen, bevor Sie es in locationManager.startUpdatingLocation() verwenden können.

Versuchen

if var options = launchOptions { 
    if options[UIApplicationLaunchOptionsLocationKey] != nil { 
     initLocationManager() 
     locationManager.startUpdatingLocation() 
    } 
} 

Answer 2

für Grund CLLocationManager Integration können Sie mit folgenden code überprüfen. Von Ihrer code ich fand, dass Sie nicht permission fragen, so erhalten Sie nil Wert.

Versuchen Sie mit unten code kann es für Sie helfen.

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { 
     // Override point for customization after application launch. 


     self.initLocationManager() 

     /* 
     if var options = launchOptions { 

      if var _: NSNumber = options[UIApplicationLaunchOptionsLocationKey] as? NSNumber { 
       locationManager.startUpdatingLocation() 
      } 
     } 
     */ 

     return true 
    } 


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

     if let lat = manager.location?.coordinate.latitude, 
      let long = manager.location?.coordinate.longitude { 

       //sends to server to update 
//    updateloc(String(lat), long: String(long)) 
     } 

    } 


    func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) { 

     if status == CLAuthorizationStatus.AuthorizedAlways { 
      locationManager.startUpdatingLocation() 
     } 
    } 


    func initLocationManager() { 

     if (nil == locationManager) { 
      locationManager = CLLocationManager() 
     } 
     locationManager.delegate = self 
     locationManager.desiredAccuracy = kCLLocationAccuracyBest 

     if #available(iOS 9.0, *) { 
      locationManager.allowsBackgroundLocationUpdates = true 
     } 

     let status = CLLocationManager.authorizationStatus() 

     if status == CLAuthorizationStatus.NotDetermined { 

      locationManager.requestAlwaysAuthorization() 

     }else if (status == CLAuthorizationStatus.AuthorizedAlways || status == CLAuthorizationStatus.AuthorizedWhenInUse) { 
      locationManager.startUpdatingLocation() 
     } 

    }
