推荐答案

实现MKMapViewDelegate协议回调，并将实现类设置为地图视图委托

Implement MKMapViewDelegate protocol callback and set the implementing class as the map view delegate

- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation {

    MKPinAnnotationView *newAnnotationPin = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"simpleAnnotation"] autorelease];
    newAnnotationPin.pinColor = MKPinAnnotationColorRed; // Or Red/Green
    return newAnnotation;

}
