Location Manager is not updating location

Question

I have the following code:

- (void) viewWillAppear {
    [self startSignificantChangeUpdates];
}



- (void)startSignificantChangeUpdates
{


    if ([CLLocationManager locationServicesEnabled])
    {
        NSLog(@"start significant changes");

        if (nil == locationManager)
            locationManager = [[CLLocationManager alloc] init];

        locationManager.delegate = self;
        [locationManager startMonitoringSignificantLocationChanges];
    }
}


problem is that the location manage is not  calling its delegate function 
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {

What can I do?

It may not solve your problem, but I would recommend using `didUpdateLocations:` instead of `didUpdateToLocation:fromLocation` (see http://stackoverflow.com/questions/12602463/didupdatelocations-instead-of-didupdatetolocation) if only because Apple has deprecated it. — Jake Spencer, Jul 30 '13 at 20:38

In your .h file:

#import <CoreLocation/CoreLocation.h>

@interface ViewController : UIViewController <CLLocationManagerDelegate>

In your .m file:

@implementation ViewController {
    // This is a private variable, used within this file only
    CLLocationManager *locationManager;
}

-(void)viewDidLoad {
    locationManager = [[CLLocationManager alloc] init];
}

-(void)viewWillAppear {
    // If the delegate is still not being set, try putting this code into viewDidAppear
    locationManager.delegate = self;
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    [locationManager startUpdatingLocation];
}

-(void)locationManger:(CLLocationManager *)manager didFailWithError:(NSError *)error {
    NSLog(@"didFailWithError: %@", error);
}

-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations {
    NSLog(@"didUpdateToLocation: %@", [locations lastObject]);
    CLLocation *currentLocation = [locations lastObject];
    [locationManager stopUpdatingLocation];
}

For more information about getting the user's location, look at this guide, which I used to implement location into an app of mine: http://www.appcoda.com/how-to-get-current-location-iphone-user/

How are you testing this? If you are running this in the simulator, you can go to Debug->Location->Freeway Drive. You can put a break point in locationManager:didUpdateToLocation method or even put a log statement to log the current location coordinates. You should see it work.

It doesn't get your current location right away? Why does it wait until you change your location? Can I change that? – Chris Hansen Jul 30 '13 at 15:54
It does get your current location. It may take a few seconds to get it though. After the current location, it would need significant change in the location to happen to report back (e.g. cell tower change). Hence, with a Freeway ride, the simulator helps you detect significant updates. – Hetal Vora Jul 30 '13 at 16:43
problem is for some reason its still not getting the user's current location even after a few seconds... – Chris Hansen Jul 30 '13 at 17:16

Please replace this line

[locationManager startMonitoringSignificantLocationChanges];

with this code

[locationController.locationManager startUpdatingLocation];

and then check

- (void)locationManager:(CLLocationManager *)manager
    didUpdateToLocation:(CLLocation *)newLocation
           fromLocation:(CLLocation *)oldLocation
{
}
