Updating MKannotation image without flashing

Question

I want to update the images of some of my annotations on a mapview every 5 seconds, however I dont\' want to remove and re-add them to the map as this causes them to \'flash\' o

Answer 1

In the case where the annotation is not nil, instead of adding and removing, try this:

annotation.customImage = ... //the new image
MKAnnotationView *av = [self.mapView viewForAnnotation:annotation];
av.image = annotation.customImage;
