Current Location returning 0

Question

My Xcode app that I am developing needs to get the latitude and longitude of the users iOS device. Although currently all I get is 0 for both values. It does not ask for permission to have the location, and I am on a real device not a simulator.

NSLocationAlwaysUsageDescription is in my info.plist

I have also imported CoreLocation and in my .h file

@interface LocationViewController : UIViewController <CLLocationManagerDelegate>

in my .m file

@interface LocationViewController () <CLLocationManagerDelegate>

Here is my code:

@implementation LocationViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    [self getCurrentLocation];
}

-(CLLocationCoordinate2D) getLocation{
    locationManager = [[CLLocationManager alloc] init];
    locationManager.delegate = self;
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    locationManager.distanceFilter = kCLDistanceFilterNone;
    [locationManager startUpdatingLocation];
    CLLocation *location = [locationManager location];
    CLLocationCoordinate2D coordinate = [location coordinate];
    return coordinate;
}

- (void)getCurrentLocation{
    CLLocationCoordinate2D coordinate = [self getLocation];
    NSString *latitude = [NSString stringWithFormat:@"%f", coordinate.latitude];
    NSString *longitude = [NSString stringWithFormat:@"%f", coordinate.longitude];
    NSLog(@"Latitude  = %@", latitude);
    NSLog(@"Longitude = %@", longitude);
}

which iOS ? I believe you are testing on iOS 8 and above... right? — Fahim Parkar, Mar 26 '15 at 06:39

Put below before startUpdatingLocation

#ifdef __IPHONE_8_0
if(IS_OS_8_OR_LATER) {
     // Use one or the other, not both. Depending on what you put in info.plist
    [self.locationManager requestWhenInUseAuthorization];
}
#endif
[self.locationManager startUpdatingLocation];

Also call [self getCurrentLocation]; in viewDidLoad & viewDidAppear both.

It will work.

Also make sure you have entry for requestWhenInUseAuthorization in info.plist file too.

check this for more info

Tried it and got an error on the if statement. I commented out the if statement and kept [self.locationManager requestWhenInUseAuthorization]; but still returns 0. Also put as you said in viewdidload/viewdidappear – Dan Winter-Wijntjes Mar 26 '15 at 06:52
@DanWinter-Wijntjes : check [here](http://stackoverflow.com/questions/26356558/mapkit-giving-wrong-lat-lang-ios-8/26361534#26361534) what I am doing.. It will work... – Fahim Parkar Mar 26 '15 at 06:59

Refer this answer. Hope, this helps.

Make this changes :

-(CLLocationCoordinate2D) getLocation{
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
[locationManager requestWhenInUseAuthorization];
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = kCLDistanceFilterNone;
[locationManager startUpdatingLocation];
CLLocation *location = [locationManager location];
CLLocationCoordinate2D coordinate = [location coordinate];
return coordinate;
}

 -(void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status
{
     NSLog(@"Status : %d", status);
}

Goto Settings > Privacy > Location > Your App > Always

And see how 'Status' value gets changes.

Perfect that worked! How do I go about getting the app to request permission for location so i don't have to change it in settings? – Dan Winter-Wijntjes Mar 26 '15 at 07:18
Add 'NSLocationAlwaysUsageDescription' in your info.plist. – itsji10dra Mar 26 '15 at 07:25
