Working With Annotation
suggest changeGet All Annotation
//following method returns all annotations object added on map
NSArray *allAnnotations = mapView.annotations;
Get Annotation View
for (id<MKAnnotation> annotation in mapView.annotations)
{
MKAnnotationView* annotationView = [mapView viewForAnnotation:annotation];
if (annotationView)
{
// Do something with annotation view
// for e.g change image of annotation view
annotationView.image = [UIImage imageNamed:@"SelectedPin.png"];
}
}
Remove All Annotations
[mapView removeAnnotations:mapView.annotations]
Remove Single Annotation
//getting all Annotation
NSArray *allAnnotations = self.myMapView.annotations;
if (allAnnotations.count > 0)
{
//getting first annoation
id <MKAnnotation> annotation=[allAnnotations firstObject];
//removing annotation
[mapView removeAnnotation:annotation];
}
