MKAnnotationView doesn't show callout

I'm trying to get an MKMapView to show a pin with a callout bubble. I get the pin to display, but I just cant figure out how to display the callout.

There is my code:

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id)annotation {
    if (annotation == mapView.userLocation) {
        return nil;
    }
    MKPinAnnotationView *pinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"Pin"];
    pinView.pinColor = MKPinAnnotationColorGreen;
    [pinView setCanShowCallout:YES];
    pinView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
    pinView.animatesDrop = YES;
    [self performSelector:@selector(displayPinCallOutView) withObject:nil afterDelay:0.3];
    return pinView;
}

If you're trying to get the callout to display as soon as the annotation is added to the map, you have to do it in the didAddAnnotationViews delegate method:

-(void)mapView:(MKMapView *)mapView didAddAnnotationViews:(NSArray *)views
{
    //Get reference to annotation you want to select...
    //You could search through mapView.annotations array
    //or keep ivar reference to it.
    id<MKAnnotation> annToSelect = ...

    [mapView selectAnnotation:annToSelect animated:YES];
}

Remove the performSelector from the viewForAnnotation method.
