How to find your current location with CoreLocation

I need to find my current location with CoreLocation, I tried multiple methods but so far my CLLocationManager has only returned 0's.. (0.000.00.000).

Here's my code (updated to work):

Imports:

#import <CoreLocation/CoreLocation.h>

Declared:

IBOutlet CLLocationManager *locationManager;
IBOutlet UILabel *latLabel;
IBOutlet UILabel *longLabel;

Functions:

- (void)getLocation { //Called when needed
    latLabel.text  = [NSString stringWithFormat:@"%f", locationManager.location.coordinate.latitude]; 
    longLabel.text = [NSString stringWithFormat:@"%f", locationManager.location.coordinate.longitude];
}

- (void)viewDidLoad {
    locationManager = [[CLLocationManager alloc] init];
    locationManager.distanceFilter = kCLDistanceFilterNone; // whenever we move
    locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters; // 100 m
    [locationManager startUpdatingLocation];
}
