Thanks in advance.

Answer 1

Try out:

It seems that [mapView selectAnnotation:annotation animated:YES] works too.

Hope this helps.

Answer 2

You just need to find your MKAnnotationView instance you want to select and call -setSelected:animated: .

For example, you can loop your annotations of an MKMapView like this:

for (YOURCLASSHERE *a in mapView.annotations) {
    // Your current position (if shown) is an annotation as well. Thus check for the right class!
    if ([a isKindOfClass:[YOURCLASSHERE class]]) {
        // insert some smart if statement here, if you have multiple annotations!
        [[mapView viewForAnnotation:a] setSelected:YES animated:YES];
    }
}

YOURCLASSHERE is your class which implements the MKAnnotation protocol.

Of course the loop is superfluous if you already know your annotationView.

Answer 3

We can show the annotation with out clicking on it. Use the following code:

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation{
     static NSString *identifier = @"Pin";

    MKPinAnnotationView *pin = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
    pin.canShowCallout = YES;
    [pin setSelected:YES animated:NO];

    return [pin autorelease];
}
