I don't need so many pins , they are crowding the area. I used the output of kml parser to draw the route between two points, how can I remove the extra pins between the route. I only need pins for beginning and ending. How do I reduce those excessive red pins\ from KML showing up.
// Locate the path to the route.kml file in the application's bundle
// and parse it with the KMLParser.
kml = [[KMLParser parseKMLAtPath:filePath] retain];
// Add all of the MKOverlay objects parsed from the KML file to the map.
NSArray *overlays = [kml overlays];
[map addOverlays:overlays];
// Add all of the MKAnnotation objects parsed from the KML file to the map.
NSArray *annotations = [kml points];
[map addAnnotations:annotations];
// Walk the list of overlays and annotations and create a MKMapRect that
// bounds all of them and store it into flyTo.
MKMapRect flyTo = MKMapRectNull;
for (id overlay in overlays) {
if (MKMapRectIsNull(flyTo)) {
flyTo = [overlay boundingMapRect];
} else {
flyTo = MKMapRectUnion(flyTo, [overlay boundingMapRect]);
}
} //overlay
for (id annotation in annotations) {
MKMapPoint annotationPoint = MKMapPointForCoordinate(annotation.coordinate);
MKMapRect pointRect = MKMapRectMake(annotationPoint.x, annotationPoint.y, 0, 0);
if (MKMapRectIsNull(flyTo)) {
flyTo = pointRect;
} else {
flyTo = MKMapRectUnion(flyTo, pointRect);
}
} ///annotation
// Position the map so that all overlays and annotations are visible on screen.
map.visibleMapRect = flyTo;
}
- (MKOverlayView *)mapView:(MKMapView *)mapView viewForOverlay:(id )overlay
{
return [kml viewForOverlay:overlay];
}
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id )annotation
{
if ([[annotation title] isEqualToString:@"Destination"])
{
MKPinAnnotationView *newAnnotation = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"greenpin"];
newAnnotation.pinColor = MKPinAnnotationColorGreen;
newAnnotation.animatesDrop = YES;
newAnnotation.canShowCallout = YES;
return newAnnotation;
}
else if ([[annotation title] isEqualToString:@"Current Location"])
{
MKPinAnnotationView *newAnnotation = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"yellowpin"];
newAnnotation.pinColor = MKPinAnnotationColorPurple;
newAnnotation.animatesDrop = YES;
newAnnotation.canShowCallout = YES;
return newAnnotation;
}
else {
return [kml viewForAnnotation:annotation];}
