Answer 1

Here's the most simple solution I could find. What it does is drops a single pin on the UIMapView in viewDidLoad event.

1. The project references MapKit framework

2. The view have the following import:#import

3. The view controller implements MKMapViewDelegate protocol

4. The view controller implementation contains:

- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id ) annotation
{
    MKPinAnnotationView *newAnnotation = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"annotation1"];
    newAnnotation.pinColor = MKPinAnnotationColorGreen;
    newAnnotation.animatesDrop = YES; 
    newAnnotation.canShowCallout = NO;
    [newAnnotation setSelected:YES animated:YES]; 
    return newAnnotation;
}

1. The viewDidLoad contains:

CLLocationCoordinate2D geos = CLLocationCoordinate2DMake(0.2344, 45.324);
MKPlacemark* marker = [[MKPlacemark alloc] initWithCoordinate:geos addressDictionary:nil];
[mapView addAnnotation:marker];
[marker release];
