Custom Pin on User's current location on iOS map using MKMapView

Question

I am trying put a pin on User's current location. Picking location from LocationManger and assigning it to MKAnnotation . But when I run the application, Map show users location and Pin location at different places on Map. Not very far but I am wondering why it's not same. Where as both custom pin and user's location are same on simulator.

Below is some of sample code.

self.locationManager = [[CLLocationManager alloc] init];
[self.locationManager requestWhenInUseAuthorization];
[self.locationManager startUpdatingLocation];

MyLocation *mylocation = [[MyLocation alloc] initWithName:@"name" address:@"address" coordinate:self.locationManager.location.coordinate] ;

Do I need to set some accuracy level? wondering how MKMapView is showing location.

Try this code:

#pragma mark -
#pragma mark MKMapView delegate
- (MKAnnotationView *)mapView:(MKMapView *)mapview viewForAnnotation:(id <MKAnnotation>)annotation
{
    if ([annotation isKindOfClass:[MKUserLocation class]])
        return nil;
    static NSString* AnnotationIdentifier = @"AnnotationIdentifier";
    MKAnnotationView *annotationView = [mapView dequeueReusableAnnotationViewWithIdentifier:AnnotationIdentifier];
    if(annotationView)
        return annotationView;
    else
    {
        MKAnnotationView *annotationView = [[[MKAnnotationView alloc] initWithAnnotation:annotation
                                                                         reuseIdentifier:AnnotationIdentifier] autorelease];
        annotationView.canShowCallout = YES;
        annotationView.image = [UIImage imageNamed:@"someImage.png"];
        UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
        [rightButton addTarget:self action:@selector(writeSomething:) forControlEvents:UIControlEventTouchUpInside];
        [rightButton setTitle:annotation.title forState:UIControlStateNormal];
        annotationView.rightCalloutAccessoryView = rightButton;
        annotationView.canShowCallout = YES;
        annotationView.draggable = YES;
        return annotationView;
    }
    return nil;
 }
