如何将.xib界面设置为自定义标注视图?

我刚刚用GUI创建了CustomCallout.xib . 我想将它用作我的注释的自定义标注,但我不知道应该在哪里设置要显示的视图以及如何将值传递给该视图 .

我要显示的 callout view 看起来像这样 .
enter image description here

这是我的 custom annotation 的代码 .

class MapPin : MKPointAnnotation {
var name: String
var street: String
var type: String
var postCode: String

init(name: String, street: String, type: String, postCode: String) {
    self.name = name
    self.street = street
    self.type = type
    self.postCode = postCode
}}

我的 view controller

import UIKit
import MapKit

class ViewController: UIViewController, MKMapViewDelegate {

@IBOutlet var mapView: MKMapView!
let span = MKCoordinateSpanMake(0.05, 0.05)


override func viewDidLoad() {
    super.viewDidLoad()

    self.mapView.delegate = self

    let location = CLLocationCoordinate2D(
        latitude: 53.430,
        longitude: 14.529)

    let region = MKCoordinateRegion(center: location, span: span)
    mapView.setRegion(region, animated: true)

    let punkt = MapPin(name: "rand", street: "rand", type: "rand", postCode: "rand")
    punkt.coordinate = location

    mapView.addAnnotation(punkt)
}

func mapView(mapView: MKMapView!, didSelectAnnotationView view: MKAnnotationView!) {
    if view.annotation.isKindOfClass(MKUserLocation){
        return
    }

    var customView = (NSBundle.mainBundle().loadNibNamed("CustomCallout", owner: self, options: nil))[0] as! CustomCallout;

    var calloutViewFrame = customView.frame;
    calloutViewFrame.origin = CGPointMake(-calloutViewFrame.size.width/2 + 15, -calloutViewFrame.size.height);
    customView.frame = calloutViewFrame;

    let cpa = view.annotation as! MapPin

    view.addSubview(customView)

    var newRegion = MKCoordinateRegion(center:cpa.coordinate, span: span)
    self.mapView.setRegion(newRegion, animated: true)
}}

不幸的是,正在运行的应用程序显示正确创建的pin具有正确的位置,但 let punkt = MapPin(name: "rand", street: "rand", type: "rand", postCode: "rand") 中的值未传递给视图,因此它看起来像这样 .

你可以在Swift中显示这样的自定义标注视图 .

func mapView(mapView: MKMapView!, didSelectAnnotationView view: MKPinAnnotationView!)
{
    if view.annotation.isKindOfClass(MKUserLocation){
        return
    }

    var customView = (NSBundle.mainBundle().loadNibNamed("SubView", owner: self, options: nil))[0] as CustomSubView;

    var calloutViewFrame = customView.frame;
    calloutViewFrame.origin = CGPointMake(-calloutViewFrame.size.width/2 + 15, -calloutViewFrame.size.height);
    customView.frame = calloutViewFrame;

    let cpa = view.annotation as CustomPointAnnotation
   //You can add set vlaues for  here
   //cpa.title
   //cpa.postCode
   //cpa.street

    view.addSubview(customView)

    //zoom map to show callout
    let spanX = 0.0000000000000001
    let spanY = 0.0000000000000001

    var newRegion = MKCoordinateRegion(center:cpa.coordinate, span: MKCoordinateSpanMake(spanX, spanY))
    self.map?.setRegion(newRegion, animated: true)
   }
