Location Services not working in iOS 8

Before `[locationManager startUpdatingLocation];`, add an iOS8 location services request:

if([locationManager respondsToSelector:@selector(requestAlwaysAuthorization)])
[locationManager requestAlwaysAuthorization];

Edit your app's `Info.plist` and add key `NSLocationAlwaysUsageDescription` with the string value that will be displayed to the user (for example, `We do our best to preserve your battery life.`)

If your app needs location services only while the app is open, replace:

`requestAlwaysAuthorization` with `requestWhenInUseAuthorization` and

`NSLocationAlwaysUsageDescription` with `NSLocationWhenInUseUsageDescription`.

I was working on an app that was upgraded to iOS 8 and location services stopped working. You'll probably get and error in the Debug area like so:

`Trying to start MapKit location updates without prompting for location authorization. Must call -[CLLocationManager requestWhenInUseAuthorization] or -[CLLocationManager requestAlwaysAuthorization] first.`

I did the least intrusive procedure. First add `NSLocationAlwaysUsageDescription` entry to your info.plist:

![Enter image description here][1]

Notice I didn't fill out the value for this key. This still works, and I'm not concerned because this is a in house app. Also, there is already a title asking to use location services, so I didn't want to do anything redundant.

Next I created a conditional for iOS 8:

if ([self.locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) {
[_locationManager requestAlwaysAuthorization];
}

After this the `locationManager:didChangeAuthorizationStatus:` method is call:

- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus: (CLAuthorizationStatus)status
{
[self gotoCurrenLocation];
}

And now everything works fine. As always, check out the [documentation][2].

**One common error for Swift developers:**

First make sure you add a value to the plist for either `NSLocationWhenInUseUsageDescription ` or `NSLocationAlwaysUsageDescription`.

If you are *still* not seeing a window pop up asking for authorization, look to see if you are putting the line `var locationManager = CLLocationManager()` in your View Controller's `viewDidLoad` method. If you do, then even if you call `locationManager.requestWhenInUseAuthorization()`, nothing will show up. This is because after viewDidLoad executes, the locationManager variable is deallocated (cleared out).

The solution is to locate the line `var locationManager = CLLocationManager()` at the top of the class method.

- (void)viewDidLoad
{

[super viewDidLoad];
self.locationManager = [[CLLocationManager alloc] init];

self.locationManager.delegate = self;
if([self.locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]){
NSUInteger code = [CLLocationManager authorizationStatus];
if (code == kCLAuthorizationStatusNotDetermined && ([self.locationManager respondsToSelector:@selector(requestAlwaysAuthorization)] || [self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)])) {
// choose one request according to your business.
if([[NSBundle mainBundle] objectForInfoDictionaryKey:@"NSLocationAlwaysUsageDescription"]){
[self.locationManager requestAlwaysAuthorization];
} else if([[NSBundle mainBundle] objectForInfoDictionaryKey:@"NSLocationWhenInUseUsageDescription"]) {
[self.locationManager requestWhenInUseAuthorization];
} else {
NSLog(@"Info.plist does not contain NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription");
}
}
}
[self.locationManager startUpdatingLocation];
}

> #pragma mark - CLLocationManagerDelegate

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
NSLog(@"didFailWithError: %@", error);
UIAlertView *errorAlert = [[UIAlertView alloc]
initWithTitle:@"Error" message:@"Failed to Get Your Location" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[errorAlert show];
}

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
NSLog(@"didUpdateToLocation: %@", newLocation);
CLLocation *currentLocation = newLocation;

if (currentLocation != nil) {
longitudeLabel.text = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.longitude];
latitudeLabel.text = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.latitude];
}
}

The problem for me was that the class that was the `CLLocationManagerDelegate` was private, which prevented all the delegate methods from being called. Guess it's not a very common situation but thought I'd mention it in case t helps anyone.

I add those key in `InfoPlist.strings` in **iOS 8.4, iPad mini 2.** It works too. I don't set any key, like `NSLocationWhenInUseUsageDescription`, in my `Info.plist`.

---
*InfoPlist.strings*:

"NSLocationWhenInUseUsageDescription" = "I need GPS information....";

---

[Base on this thread][1], it said, `as in iOS 7`, can be localized in the InfoPlist.strings. In my test, those keys can be configured directly in the file `InfoPlist.strings`.

**UPDATE:**

I think [`@IOS`'s method is better.][2] Add key to `Info.plist` with empty value and add localized strings to `InfoPlist.strings`.

Enjoy.

This is issue with ios 8
Add this to your code

if (IS_OS_8_OR_LATER)
{
[locationmanager requestWhenInUseAuthorization];

[locationmanager requestAlwaysAuthorization];
}
and to info.plist:

<key>NSLocationUsageDescription</key>
<string>I need location</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>I need location</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>I need location</string>

- (void)startLocationManager
{
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.distanceFilter = kCLDistanceFilterNone; //whenever we move
locationManager.desiredAccuracy = kCLLocationAccuracyBest;

[locationManager startUpdatingLocation];
[locationManager requestWhenInUseAuthorization]; // Add This Line


}


And to your info.plist File

I get a similar error in iOS9 (working with Xcode 7 and Swift 2):
**Trying to start MapKit location updates without prompting for location authorization. Must call -[CLLocationManager requestWhenInUseAuthorization] or -[CLLocationManager requestAlwaysAuthorization] first.**
I was following a tutorial but the tutor was using iOS8 and Swift 1.2. There are some changes in Xcode 7 and Swift 2, I found this code and it works fine for me (if somebody needs help):

import UIKit
import MapKit
import CoreLocation

class MapViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate {

// MARK: Properties
@IBOutlet weak var mapView: MKMapView!

let locationManager = CLLocationManager()

override func viewDidLoad() {
super.viewDidLoad()

self.locationManager.delegate = self
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
self.locationManager.requestWhenInUseAuthorization()
self.locationManager.startUpdatingLocation()
self.mapView.showsUserLocation = true

}

// MARK: - Location Delegate Methods

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let location = locations.last
let center = CLLocationCoordinate2D(latitude: location!.coordinate.latitude, longitude: location!.coordinate.longitude)
let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 1, longitudeDelta: 1))
self.mapView.setRegion(region, animated: true)
}

func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
print("Errors: " + error.localizedDescription)
}
}

Finally, I put that in info.plist:
Information Property List: **NSLocationWhenInUseUsageDescription**
Value: **App needs location servers for staff**
