如何向MKPointAnnotation添加按钮？

我只是试图在我的注释点添加一个细节按钮,不幸的是我不知道该怎么做.有人可以帮我吗？

下图显示了我想要实现的目标.谢谢!

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

你做得对.你只需要实现这些方法来添加按钮以及标题和副标题


  
iOS 8和Xcode 6

        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()
    }

    // When user taps on the disclosure button you can perform a segue to navigate to another view controller
    func mapView(mapView: MKMapView!, annotationView view: MKAnnotationView!, calloutAccessoryControlTapped control: UIControl!) {
        if cOntrol== view.rightCalloutAccessoryView{
            println(view.annotation.title) // annotation's title
            println(view.annotation.subtitle) // annotation's subttitle

            //Perform a segue here to navigate to another viewcontroller
            // On tapping the disclosure button you will get here
        }
    }

    // Here we add disclosure button inside annotation window
    func mapView(mapView: MKMapView!, viewForAnnotation annotation: MKAnnotation!) -> MKAnnotationView! {

        println("viewForannotation")
        if annotation is MKUserLocation {
            //return nil 
            return nil
        }

        let reuseId = "pin"
        var pinView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseId) as? MKPinAnnotationView

        if pinView == nil {
            //println("Pinview was nil")
            pinView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseId)
            pinView!.canShowCallout = true
            pinView!.animatesDrop = true
            }

        var button = UIButton.buttonWithType(UIButtonType.DetailDisclosure) as UIButton // button with info sign in it

        pinView?.rightCalloutAccessoryView = button


        return pinView
    }


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

        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()

        // Adding button here wont do anything  so remove these two lines


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

        // For adding button we have to use a method named as viewForAnnotation 

        for(var i = 0; i 

看看我的输出.

两个建议:1.如果您成功出列了之前的`MKPinAnnotationView`,请不要忘记重置`annotation`属性.实际上,如果重用"MKPinAnnotationView",它可能不会在正确的位置.2.按钮语法现在是`UIButton(type:.DetailDisclosure)`.
