Ich möchte den Button in einem Pin mit einem anderen View Controller verbinden, in der func mapView anstatt zu drucken ("Disclosure Pressed"). Wenn Sie auf die Schaltfläche tippen, wird ein neuer View Controller mit einem Teil der Karte und weiteren Dingen angezeigt.Wie kann ich einen View Controller programmgesteuert über eine Schaltfläche mit Swift 2 öffnen?

func dropPinZoomIn(placemark:MKPlacemark)

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
