方法1

- (BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id <BMKAnnotation>)annotation

{

if ([annotation isKindOfClass:[BMKPointAnnotationclass]]) {

BMKPinAnnotationView*newAnnotationView =[[BMKPinAnnotationViewalloc]initWithAnnotation:annotation reuseIdentifier:@"myAnnotation"

        newAnnotationView.pinColor=BMKPinAnnotationColorPurple;

        newAnnotationView.animatesDrop=YES;// 設定該標註點動畫顯示

        newAnnotationView.annotation=annotation;

        newAnnotationView.image = [UIImageimageNamed:@"IcoAddress.png"];   //把大頭針換成別的圖片

return newAnnotationView;

    }

returnnil;

}

利用繼承
