Question

在AppDelegate中获取用户的经度和纬度它在我删除时请求了一次权限\在重新安装后再次在模拟器上卸载应用程序它没有请求权限因此应用程序一直在崩溃是我的代码

 func initLocationManager() {

    if( CLLocationManager.authorizationStatus() == CLAuthorizationStatus.AuthorizedWhenInUse ||
        CLLocationManager.authorizationStatus() == CLAuthorizationStatus.Authorized){

        seenError = false
        locationFixAchieved = false
        locationManager = CLLocationManager()
        locationManager.delegate = self
        //        locationManager.locationServicesEnabled = true
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.startUpdatingLocation()
        locationManager.requestAlwaysAuthorization()

    }
}

// Location Manager Delegate stuff

func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) {
    locationManager.stopUpdatingLocation()
    if ((error) != nil) {
        if (seenError == false) {
            seenError = true
            print(error)
        }
    }
}

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    if (locationFixAchieved == false) {
        locationFixAchieved = true
        var locationArray = locations as NSArray
        var locationObj = locationArray.lastObject as! CLLocation
        var coord = locationObj.coordinate

        LATITUDE = coord.latitude
        LONGITUDE = coord.longitude

        print(coord.latitude)
        print(coord.longitude)
    }
}



func locationManager(manager: CLLocationManager!,
                     didChangeAuthorizationStatus status: CLAuthorizationStatus) {
    var shouldIAllow = false

    switch status {
    case CLAuthorizationStatus.Restricted:
        locationStatus = "Restricted Access to location"
    case CLAuthorizationStatus.Denied:
        locationStatus = "User denied access to location"
    case CLAuthorizationStatus.NotDetermined:
        locationStatus = "Status not determined"
    default:
        locationStatus = "Allowed to location Access"
        shouldIAllow = true
    }
    NSNotificationCenter.defaultCenter().postNotificationName("LabelHasbeenUpdated", object: nil)
    if (shouldIAllow == true) {
        NSLog("Location to Allowed")
        // Start location services
        locationManager.startUpdatingLocation()
    } else {
        NSLog("Denied access: \(locationStatus)")
    }
}

尝试首次获取didFinishLaunchingWithOptions的用户位置，然后调用此方法获取更新的用户位置。

locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()


func locationManager(manager:CLLocationManager, didUpdateLocations locations:AnyObject[]) {
println("locations = \(locations)")
gpsResult.text = "success"
}

Iphone模拟器没有获得位置
