How do I display annotations titles for an array of locations on MapKit

Question

I'm filtering some Google Places data and then displaying each location on a map view. currently I have all the points displaying on the map. I need to figure out how to show a annotationPoint.title = place.name; for each of these locations.

Any idea how I'd go about doing this for the entire array of location places?

thanks so much for any help!

 //UPDATE - to handle filtering
    - (void)googlePlacesConnection:(GooglePlacesConnection *)conn didFinishLoadingWithGooglePlacesObjects:(NSMutableArray *)objects 
    {

        if ([objects count] == 0) {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"No matches found near this location" 
                                                            message:@"Try another place name or address" 
                                                           delegate:nil 
                                                  cancelButtonTitle:@"OK" 
                                                  otherButtonTitles: nil];
            [alert show];
        } else {
            locations = objects;
            //UPDATED locationFilterResults for filtering later on
            locationsFilterResults = objects;
            [tableView reloadData];

            [mapView removeAnnotations:mapView.annotations];
            [mapView addAnnotations:objects];

        }
    }

try this code:

    [mapView setMapType:MKMapTypeStandard];

    region.center.longitude = 13.40629;
    region.span.longitudeDelta = 0.01f;
    region.span.latitudeDelta = 0.01f;
    [mapView setRegion:region animated:YES]; 

    [mapView setDelegate:self];

    DisplayMap *gann = [[DisplayMap alloc] init]; 
    gann.title = @"Berlin";
    gann.subtitle = @"Germany"; 
    gann.coordinate = region.center; 
    [mapView addAnnotation:gann];


    MKCoordinateRegion region1 = { {0.0, 0.0 }, { 0.0, 0.0 } }; 
    region1.center.latitude = 51.050991 ;

    [mapView setRegion:region1 animated:YES]; 


    DisplayMap *gann1 = [[DisplayMap alloc] init]; 
    gann1.title = @"Dresden";
    gann1.subtitle = @"Germany"; 
    gann1.coordinate = region1.center; 
    [mapView addAnnotation:gann1];


    MKCoordinateRegion region2 = { {0.0, 0.0 }, { 0.0, 0.0 } }; 
    region2.center.latitude = 50.111445 ;
    region2.center.longitude = 8.680615;
    region2.span.longitudeDelta = 0.01f;
    region2.span.latitudeDelta = 0.01f;
    [mapView setRegion:region2 animated:YES]; 


    DisplayMap *gann2 = [[DisplayMap alloc] init];
