How to trigger MKAnnotationView's callout view without touching the pin?

Question

I\'m working on a MKMapView with the usual colored pin as the location points. I would like to be able to have the callout displayed without touching the pin.

Answer 1

This does not work for me. I suspect a bug in the MapKit API.

See this link for details of someone else for who this is not working: http://www.iphonedevsdk.com/forum/iphone-sdk-development/19740-trigger-mkannotationview-callout-bubble.html#post110447

--edit--

Okay after screwing with this for a while, here is what I've been able to make work:

for (id currentAnnotation in mapView.annotations) {       
    if ([currentAnnotation isEqual:annotationToSelect]) {
        [mapView selectAnnotation:currentAnnotation animated:FALSE];
    }
}

Note, this requires implementing - (BOOL)isEqual:(id)anObject for your class that implements the MKAnnotation protocol.
