印刷の代わりにfunc mapView内の別のView Controllerにピンのボタンを接続したいとします（ "Disclosure Pressed"）。ボタンをタップすると、マップの一部とそれ以上のもので新しいView Controllerが表示されます。Swift 2のボタンからプログラムでView Controllerを開くにはどうすればよいですか？
import UIKit
import MapKit
protocol HandleMapSearch {
func dropPinZoomIn(placemark:MKPlacemark)
}
class ViewController: UIViewController {
let locationManager = CLLocationManager()
var resultSearchController:UISearchController? = nil
var selectedPin:MKPlacemark? = nil
@IBOutlet weak var mapView: MKMapView!
override func viewDidLoad() {
super.viewDidLoad()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestWhenInUseAuthorization()
locationManager.requestLocation()
//
let locationSearchTable = storyboard!.instantiateViewControllerWithIdentifier("LocationSearchTable") as! LocationSearchTable
resultSearchController = UISearchController(searchResultsController: locationSearchTable)
resultSearchController?.searchResultsUpdater = locationSearchTable
//
let searchBar = resultSearchController!.searchBar
searchBar.sizeToFit()
searchBar.placeholder = "Search for places"
navigationItem.titleView = resultSearchController?.searchBar
//
resultSearchController?.hidesNavigationBarDuringPresentation = false
resultSearchController?.dimsBackgroundDuringPresentation = true
definesPresentationContext = true
//
locationSearchTable.mapView = mapView
//
locationSearchTable.handleMapSearchDelegate = self
//
