I would change the color from red to green of an annotation when the user pin tapped addition to changing its title and subtitle.
I am truly lost. I searched how to make a custom annotation pin, ok. I found the implementation of the method when the user touches the pin didSelectAnnotationView and it works when I tap the annotation NSLog(@"Tap") ; , but now I can not change the pin that was touched.
Thank you very much everyone for your contributions.
Ciao
To set the pin color, make use of MKPinAnnotationView pinColor property.
MKPinAnnotationView *pin = [[MKPinAnnotationView alloc] init]
pin.pinColor = MKPinAnnotationColorGreen;
For custom annotation image, set the image property, as such.
UIImage *annImage = [UIImage imageNamed:@"AnnotationIcon.png"];
annView.image = annImage;
Do note that the MKPinAnnotationView animateDrop property will not work on custom images. There's a way to duplicate that animation though. See How do I animate MKAnnotationView drop?
Update So bascially, you do this if you wanna change from red to green upon being selected.
- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKPinAnnotationView *)view {
view.pinColor = MKPinAnnotationColorGreen;
}
- (MKAnnotationView *)mapView:(MKMapView *)aMapView
viewForAnnotation:(id)ann {
NSString *identifier = @"myPin";
MKPinAnnotationView *annView = (MKPinAnnotationView *)
[aMapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (annView == nil) {
annView= [[[MKPinAnnotationView alloc] initWithAnnotation:ann
reuseIdentifier:identifier]
autorelease];
} else {
annView.annotation = ann;
}
// you can define the properties here.
return annView;
}
In your method set the pinColor property of your MKAnnotationView as follows:
annotationView.pinColor = MKPinAnnotationColorRed; // Green or Purple
(re) look this :
- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKPinAnnotationView *)view {
view.pinColor = MKPinAnnotationColorGreen;
}
this is a MKPinAnnotationView (and not MKAnnotationView) in param
