I have successfully changed MKAnnotationView to use my custom image with the following code snippet. However, my problem is that once I enable default pin animation using
annotationView.animatesDrop = YES;
The custom image is gone and default red pin is used. Is there any way to fix this? Thanks
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(MyAnnotation *)annotation
{
if ([annotation isKindOfClass:[MKUserLocation class]])
return nil;
// try to dequeue an existing pin view first
static NSString* identifier = @"AnnotationIdentifier";
MKPinAnnotationView *annotationView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (annotationView == nil) {
annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
annotationView.enabled = YES;
annotationView.canShowCallout = YES;
//!!!!!!!annotationView.animatesDrop = YES;!!!!!!!!!!
} else {
annotationView.annotation = annotation;
}
annotationView.image = [UIImage imageNamed:@"bla.png"];
return annotationView;
}
Try smth like this:
- (void)loadView {
self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
self.view.backgroundColor = [UIColor grayColor];
[self.view setClipsToBounds:YES];
MKMapView *mapView = [[MKMapView alloc] initWithFrame:CGRectMake(10, 10, self.view.frame.size.width - 20, self.view.frame.size.height - 20)];
mapView.delegate = self;
[mapView setAutoresizingMask:UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight];
mapView.mapType = MKMapTypeStandard;
[self.view addSubview:mapView];
}

- (void)mapView:(MKMapView *)mapView didAddAnnotationViews:(NSArray *)views {
for (MKAnnotationView *pin in views) {
//UIButton *detailsButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
//[detailsButton addTarget:self action:@selector(detailsButtonAct:) forControlEvents:UIControlEventTouchUpInside];
pin.canShowCallout = YES;
//pin.rightCalloutAccessoryView = detailsButton;
CGRect endFrame = pin.frame;
pin.frame = CGRectOffset(pin.frame, 0, -230);
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.45f];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
pin.frame = endFrame;
[UIView commitAnimations];
}
}
- (MKAnnotationView *)mapView:(MKMapView *)map viewForAnnotation:(id <MKAnnotation>)annotation {
static NSString *AnnotationViewID = @"annotationViewID";
MKAnnotationView *annotationView = (MKAnnotationView *)[map dequeueReusableAnnotationViewWithIdentifier:AnnotationViewID];
if (annotationView == nil)
annotationView = [[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID] autorelease];
annotationView.image = [UIImage imageNamed:@"map_pin.png"];
annotationView.annotation = annotation;
[annotationView addObserver:self forKeyPath:@"selected" options:NSKeyValueObservingOptionNew context:@"pinSelected"];
[annotationView setEnabled:YES];
return annotationView;
