Answer 1

For that you can use the rightCalloutAccessoryView and leftCalloutAccessoryView.

Here an example how to use the rightCalloutAccessoryView.

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

 if ([annotation isKindOfClass: [MKUserLocation class]]) {
    return nil;
}

static NSString* AnnotationIdentifier = @"AnnotationIdentifier";
MKPinAnnotationView *pinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationIdentifier];

[pinView setCanShowCallout:YES];
if([annotation isKindOfClass:[ASPinAnnotation class]])
{
    [pinView setPinColor:MKPinAnnotationColorRed];
}
else if([annotation isKindOfClass:[ASAddAutomatPin class]])
{
    UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
    [rightButton setTitle:[annotation title] forState:UIControlStateNormal];
    [pinView setRightCalloutAccessoryView:rightButton];
    [pinView setPinColor:MKPinAnnotationColorPurple];
}

And to get notified when a calloutAccessoryView is tapped you have to use this function in your delegate:

   -(void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
   {

if([(UIButton*)control buttonType] == UIButtonTypeDetailDisclosure)
{
    ASAddViewController *addController = [[ASAddViewController alloc] init];
    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:addController];
    [addController setDelegate:self];
    [self.controller presentViewController:navController animated:YES completion:nil];
}

}
