Having problems with iOS8 Core Location - ios

Question

Core Location usage change recently, but even after updating to the new specification I can't seem to get it working.
I tried starting a new project with just a view controller that changes its background color upon GPS coordinate finding or failure.
#import "ViewController.h"
#interface ViewController (){
CLLocationManager *locationManager;
}
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
if (locationManager == nil)
{
locationManager = [[CLLocationManager alloc] init];
}
locationManager.delegate = self;
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
if (![CLLocationManager locationServicesEnabled]) {
[self.view setBackgroundColor:[UIColor redColor]];
}
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
[locationManager requestAlwaysAuthorization];
[locationManager startUpdatingLocation];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#pragma mark CLLocationManagerDelegate
//
//
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation
{
[self.view setBackgroundColor:[UIColor greenColor]];
NSLog(#"lat:%f lon:%f", newLocation.coordinate.latitude, newLocation.coordinate.longitude);
}
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
//Debug(#"did fail with error. stop updating and return error.");
[self.view setBackgroundColor:[UIColor orangeColor]];
}
#end
I added
<key>NSLocationAlwaysUsageDescription</key>
<string>This app needs your location to provide the best service.</string>
to the Info.plist file, and still... no changes, the location icon appears on the status bar near the battery but no location ever comes, real or simulated.
Am I missing something?

Try adding the change authorisation method:
- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status
{
// This method has to be here to trigger the UIAlertView
switch (status) {
case kCLAuthorizationStatusDenied:
break;
case kCLAuthorizationStatusRestricted:
break;
case kCLAuthorizationStatusNotDetermined: {
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
[self.locationManager requestAlwaysAuthorization];
}
default:
break;
}
}
EDIT
You're using the wrong delegate method. didUpdateToLocation has been deprecated. Use this instead:
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations {}
