Swift Parse MapView 不显示 CalloutAccessory 和 Segueing

Question

我目前有一个 UIMapView，其中为 map 上用户的不同位置固定了不同的注释。单击注释时，我试图转到相应的用户配置文件。这是我设置注释的代码:

let query = PFQuery(className: "location")

query.findObjectsInBackground { (objects, error) in

    if let brandsLocation = objects {

        for object in brandsLocation {

            if let brandLocation = object as? PFObject {

                let annotation = MKPointAnnotation()

                let annotationPoint = object["geoPoint"] as! PFGeoPoint

                annotation.coordinate = CLLocationCoordinate2DMake(annotationPoint.latitude, annotationPoint.longitude)

                annotation.title = brandLocation["annotationTitle"] as? String

                annotation.subtitle = brandLocation["annotationSubtitle"] as? String

                self.map.addAnnotation(annotation)
            }
        }
    }
}

这是我认为应该发生转场的地方，但由于某种原因它没有做任何事情。

// 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{

        performSegue(withIdentifier: "goToUserProfile", sender: view)

        print(view.annotation?.title) // annotation's title

        print(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! {

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

    let reuseId = "pin"
    var pinView = mapView.dequeueReusableAnnotationView(withIdentifier: reuseId) as? MKPinAnnotationView

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

    let button = UIButton(type: UIButtonType.detailDisclosure) as UIButton // button with info sign in it

    pinView?.rightCalloutAccessoryView = button

    return pinView
}

我希望在单击或双击注释时发生转场，然后在发送特定用户名信息的同时对新 View Controller 执行转场。我很确定我能够发送用户信息，但我只需要弄清楚如何进行转场。我认为这可能与新的 XCode 更新中我的 calloutaccessory 尚未显示有关。这是我的应用程序的屏幕截图。 MapView Annotation

使用didSelect方法代替calloutAccessoryControlTapped怎么样？

func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {
    performSegue(withIdentifier: "goToUserProfile", sender: view)
    print(view.annotation?.title) // annotation's title
    print(view.annotation?.subtitle) // annotation's subttitle
}
