Jak dodać przycisk do wpisu MKPointAnnotation?

Question

Po prostu utknąłem, próbując dodać przycisk szczegółów do mojej adnotacji, niestety nie wiem jak to zrobić. Czy ktoś może mi w tym pomóc?

Poniższy rysunek przedstawia to, co chciałbym osiągnąć. Dzięki!

MapKitViewController:

import UIKit 
import MapKit 
import CoreLocation 

class MapKitViewController: UIViewController, MKMapViewDelegate 
{ 

let locationManager = CLLocationManager() 

@IBOutlet weak var nmapView: MKMapView! 
override func viewDidLoad() 
{ 
    super.viewDidLoad() 
    locationManager.requestWhenInUseAuthorization() 
    locationManager.startUpdatingLocation() 
    let location = CLLocationCoordinate2D(
     latitude: 53.4265107, 
     longitude: 14.5520357) 

    let span = MKCoordinateSpanMake(0.05, 0.05) 
    let region = MKCoordinateRegion(center: location, span: span) 
    nmapView.setRegion(region, animated: true) 
    nmapView.showsPointsOfInterest = false 
    nmapView.showsUserLocation = true 
    displayMarkers() 
} 

func displayMarkers() -> Void 
{ 
    let jsonURL: NSURL = NSURL(string: "http://jsonstring.com/")! 

    var dataFromNetwork: NSData = NSData(contentsOfURL: jsonURL)! 
    let json = JSON(data: dataFromNetwork) 
    var jsonSize = json.count 

    var todaysDate:NSDate = NSDate() 
    var dateFormatter:NSDateFormatter = NSDateFormatter() 
    dateFormatter.dateFormat = "yyyy-MM-dd" 
    var formattedDate:String = dateFormatter.stringFromDate(todaysDate) 

    let annotationView = MKAnnotationView() 
    let detailButton: UIButton = UIButton.buttonWithType(UIButtonType.DetailDisclosure) as UIButton 
    annotationView.rightCalloutAccessoryView = detailButton 


    for(var i = 0; i < jsonSize; i++) 
    { 
     if(json[i]["rozpoczecie"].stringValue == formattedDate) 
     { 
      let clubID = json[i]["id_klub"].stringValue 
      let annotation = MKPointAnnotation() 
      let (resultSet, err) = SD.executeQuery("SELECT * FROM Clubs WHERE ID = ?", withArgs: [clubID]) 
      if(err != nil){println("blad")} 
      else 
      { 
       for row in resultSet 
       { 
        let name = row["Name"]?.asString() 
        let latitude = row["Latitude"]?.asDouble() 
        let longitude = row["Longitude"]?.asDouble() 
        annotation.title = name 
        var markerLatitude: Double = latitude! 
        var markerLongitude: Double = longitude! 
        let location = CLLocationCoordinate2D(latitude: markerLatitude, longitude: markerLongitude) 
        annotation.setCoordinate(location) 
        annotation.subtitle = json[i]["nazwa"].stringValue 
       } 
       nmapView.addAnnotation(annotation) 
      } 
     } 
    } 
}
