Answer 1

A CLPlacemark doesn't implement the MKAnnotation protocol so you still have to create your own annotation class or you can use MKPointAnnotation. The coordinates of the placemark are in its location property.

For example:

MKPointAnnotation *pa = [[MKPointAnnotation alloc] init];
pa.coordinate = placemark.location.coordinate;
pa.title = ABCreateStringWithAddressDictionary(placemark.addressDictionary, YES);
[mapView addAnnotation:pa];
[pa release];  //remove if using ARC

You can set the title to anything you want from the placemark but one possibility, as shown in the example, is to use the Address Book UI framework to generate an address string from the address dictionary provided by the placemark.
