I'm a noob to iphone development and i'm trying to add a custom button to an annotation callout. I have no problems adding a regular button to rightCalloutAccessoryView, but it's just not working for custom style. My image size is 32 x 32. I also want to add a custom map pin following this stackoverflow question here Any help is greatly appreciated.

MY CODE

-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
// Define your reuse identifier.
static NSString *identifier = @"MapPoint";   

if ([annotation isKindOfClass:[MapPoint class]]) {
    MKPinAnnotationView *annotationView = (MKPinAnnotationView *) [self.mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
    if (annotationView == nil) {
        annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
    } else {
        annotationView.annotation = annotation;
    }
    annotationView.enabled = YES;
    annotationView.canShowCallout = YES;
    annotationView.animatesDrop = YES;
    annotationView.image = [UIImage imageNamed:@"myimage.png"];

    UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeCustom];
    //UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
    [rightButton setImage:[UIImage imageNamed:@"phony2.png"] forState:UIControlStateNormal];
    [rightButton addTarget:self
                    action:@selector(showDetails:)
          forControlEvents:UIControlEventTouchUpInside];
    annotationView.rightCalloutAccessoryView = rightButton;

    return annotationView;
}
return nil;

}

 [rightButton addTarget:self
                action:@selector(showDetails:)

Remove this line and set frame of the button

[rightButton setFrame:CGRectMake(0,0,32,32)];

and get the tap action from the degate method

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control;

where you get the annotation view.

Hope this will help you.
