Swift - 执行地图注释中的Segue

Question

我在地图上有1个针脚。我需要将注释的标题传递给另一个UIView（在这种情况下是ikinciEkran.swift）。但我无法这样做。

这里是我的代码的segue部分，我不知道如何缩减选定注释的标题。

我只粘贴了代码的相关部分。

class MapViewController: UIViewController, CLLocationManagerDelegate, MKMapViewDelegate { 

@IBOutlet weak var mapView: MKMapView! 
@IBOutlet weak var lbl_Name: UILabel! 
@IBOutlet weak var lbl_Address: UILabel! 
@IBOutlet weak var lbl_Phone: UILabel! 

var LocationManager = CLLocationManager() 

var i = 0 

var annotation:MKAnnotation! 

override func viewDidLoad() { 
    super.viewDidLoad() 

    LocationManager.delegate = self 
    mapView.delegate = self 

    LocationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters 
    LocationManager.requestWhenInUseAuthorization() 
    LocationManager.startUpdatingLocation() 

    let tekel1 = TekelClass(
     title: "tekel1", 
     locationName: "Tekelİsim1", 
     coordinate: CLLocationCoordinate2D(latitude: 40.9400, longitude: 29.300520)) 

    mapView.addAnnotation(tekel1) 

} 

func mapView(mapView: MKMapView!, annotationView view: MKAnnotationView!, 
    calloutAccessoryControlTapped control: UIControl!) { 
     if control == view.rightCalloutAccessoryView { 
      performSegueWithIdentifier("toTheMoon", sender: self) 

     } 
} 

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
    if (segue.identifier == "toTheMoon") 
    { 
     var ikinciEkran = segue.destinationViewController as! DetailViewController 

     ikinciEkran.tekelName = "how to segue title of the selected pin" 

    } 

}

您需要实施viewForAnnotation方法。

示例。

func mapView(mapView: MKMapView!, viewForAnnotation annotation: MKAnnotation!) -> MKAnnotationView! { 

    if annotation is MKUserLocation { 
     return nil 
    } 

    let reuseId = "pin" 

    var pinView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseId) 
    if pinView == nil { 
     pinView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseId) 
     pinView?.canShowCallout = true 

     var rightButton: AnyObject! = UIButton.buttonWithType(UIButtonType.DetailDisclosure) 
     rightButton.titleForState(UIControlState.Normal) 

     pinView!.rightCalloutAccessoryView = rightButton as! UIView 
    } 
    else { 
     pinView?.annotation = annotation 
    } 

    return pinView 
} 

如果用户点击（i）按钮的注释，calloutAccessoryControlTapped将被调用。

参考。我的MKMapView示例代码 https://github.com/koogawa/MKMapViewSample

func mapView(mapView: MKMapView, annotationView view: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) { 
    if control == view.rightCalloutAccessoryView { 
     performSegueWithIdentifier("toTheMoon", sender: view) 
    } 
} 

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
    if (segue.identifier == "toTheMoon") 
    { 
     var ikinciEkran = segue.destinationViewController as! DetailViewController 

     ikinciEkran.tekelName = (sender as! MKAnnotationView).annotation!.title 

    } 

}
