MapKitで一連の場所の注釈のタイトルを表示するには

Question

Googleプレイスのデータをフィルタリングして、各場所をマップビューに表示しています。現在、私はすべてのポイントを地図上に表示しています。私はどのように表示するかを理解する必要がありますannotationPoint.title = place.name;これらの場所ごとに

どのように私は場所の場所の配列全体のためにこれを行うに行くだろうか？

ご協力いただきありがとうございます！

//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]; 

     } 
    }

このコードを試してみてください。
