Objective-c iOS - Can't receive delegate methods in my custom class - objective-c

Question

My custom class needs to receive the "didUpdateToLocation" CLLocationManagerDelegate method, however i can't seem to make the following code work.
Header file.
#import <Foundation/Foundation.h>
#import <CoreLocation/CoreLocation.h>
#import <MapKit/MapKit.h>
#interface MyCurrentLocation : NSObject<MKAnnotation,CLLocationManagerDelegate,MKMapViewDelegate>
{
CLLocationCoordinate2D coordinate;
}
#property (nonatomic, assign) CLLocationCoordinate2D coordinate;
#property (nonatomic, copy) CLLocationManager *locationManager;
-(MyCurrentLocation *)init;
#end
Implementation file.
#import "MyCurrentLocation.h"
#implementation MyCurrentLocation
-(BLCurrentLocation *)init
{
self = [super init];
if (self) {
_locationManager = [[CLLocationManager alloc] init];
_locationManager.delegate = self;
_locationManager.distanceFilter = kCLDistanceFilterNone;
_locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters;
[_locationManager startUpdatingLocation];
}
return self;
}
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
NSLog(#"Did we receive a location?");
}

Answer 1

You have to respond to other delegate methods, such as the error callback. Also, check for the CLLocationManager's + (CLAuthorizationStatus)authorizationStatus class method to determine if you are able to use location services.

Answer 2

I don't know why but maybe you can try to implement this delegate method to see if location service cannot be registered.
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Error" message:#"Please make sure Location Service is ON" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alertView show];
}
