Answer 1

Try using following delegate method of Map View. You can set right call out accessory view as button

- (MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id <MKAnnotation>)annotation{

MKAnnotationView *view = nil; 
//MKPinAnnotationView *view=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"HotSpotsLoc"];

if(annotation !=mapView.userLocation){
    view = (MKAnnotationView *) 
    [mapView dequeueReusableAnnotationViewWithIdentifier:@"identifier"]; 
    if(nil == view) { 
        view = [[[MKAnnotationView alloc] 
                 initWithAnnotation:annotation reuseIdentifier:@"identifier"] 
                autorelease];           
    }


    ParkPlaceMark *currPlaceMark = annotation;
    NSLog(@"%i",currPlaceMark.position);

        view.image = [UIImage imageNamed:@"pin.png"];

    UIButton *btnViewVenue = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
    view.rightCalloutAccessoryView=btnViewVenue;
    view.enabled = YES;
    view.canShowCallout = YES;
    view.multipleTouchEnabled = NO;
    //view.animatesDrop = YES;

}       
return view;
}
