Using MKMapViewDelegate - objective-c

Question

I can't understand why it's not working.
I have a map with a marker, I would like to change the icon
map.h:
#define METERS_PER_MILE 1609.344
#interface Map : UIViewController<CLLocationManagerDelegate,MKMapViewDelegate>{
IBOutlet MKMapView *map;
CLLocationManager *locationManager;
}
#property(nonatomic,retain) IBOutlet MKMapView *map;
#property(nonatomic,retain)IBOutlet UIWindow *window;
#property (nonatomic, readwrite) CLLocationCoordinate2D location;
- (void)setMarkers:(MKMapView *)mv;
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation;
#end
And in map.m this:
#implementation Map
#synthesize map, window, location;
- (void)setMarkers:(MKMapView *)mv
{
//no necesary here
}
- (void)viewWillAppear:(BOOL)animated {
// 1
location.latitude = 38.989567;
location.longitude= -1.856283;
// 2
MKCoordinateRegion viewRegion = MKCoordinateRegionMakeWithDistance(location, 0.8*METERS_PER_MILE, 0.8*METERS_PER_MILE);
// 3
MKCoordinateRegion adjustedRegion = [map regionThatFits:viewRegion];
// 4
[map setRegion:adjustedRegion animated:YES];
//[self setMarkers: map];
CLLocationCoordinate2D pointCoord = location;
NSString *theTitle = #"title";
NSString *theSubtitle = #"subtitle";
MapPoint *mp = [[MapPoint alloc] initWithCoordinate:pointCoord title:theTitle subTitle:theSubtitle];
[map addAnnotation:mp];
}
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
NSLog(#"here!!");
static NSString *identifier = #"MyLocation";
if ([annotation isKindOfClass:[MapPoint class]]) {
MKPinAnnotationView *annotationView = (MKPinAnnotationView *) [map dequeueReusableAnnotationViewWithIdentifier:identifier];
if (annotationView == nil) {
annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
} else {
annotationView.annotation = annotation;
}
annotationView.enabled = YES;
annotationView.canShowCallout = YES;
annotationView.image=[UIImage imageNamed:#"Icon.png"];//here we use a nice image instead of the default pins
return annotationView;
}
return nil;
}
#end
The viewForAnnotation is never executed (I ckeck this with NSLog)
What should I do?
Thank you in advance

Looks like there's nothing wrong with your code. As phix23 said, you may missed to link the MKMapView with the delegate:
