Custom icon and default current location icon on Map when needed in iPhone

I have an application where in I give user 2 options. 1. Select your current location through GPS 2. Enter your current location manually.

What I want is When user has selected thh first option then I have to display the blue animated icon for current location And when user has selected 2nd option then I have to display my own custom icon for current location.

Is it possible? Suggestions are most welcomed.

Thanks.

Solution

  • First set a boolean variable for Example isInGPSMode

    now apply following code

    if(isInGPSMode==TRUE)
{
     mapViewHome.showsUserLocation=TRUE;
}
else
{
     mapViewHome.showsUserLocation=FALSE;
}

    and handle the map view delegate as

    - (MKAnnotationView *) mapView:(MKMapView *)mapView1 viewForAnnotation:(id <MKAnnotation>) annotation
{
    if(annotation==mapViewHome.userLocation)
    {
        return nil;
    }
    addAnnonation *tempAnnonation=(addAnnonation *)annotation;

    MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentloc"];
    annView.pinColor = MKPinAnnotationColorRed;
    return annView;

}
