快速新手问题:

我有两个视图控制器:我的家用VC,它使用MapKit和第二个“MapDetailViewController”来显示附加信息

在home VC上,我添加了一个带有注释的兴趣点,当用户单击pin时,可以显示该点的名称和字幕。当用户单击地图批注时,如何切换到我的MapDetailViewController

// Map view delegate which handles the annotation view
    extension ViewController: MKMapViewDelegate {
    func mapView(_ mapView: MKMapView, viewFor annotation: 
        MKAnnotation) -> 

MKAnnotationView? {

    guard let annotation = annotation as? Artwork else { return nil }

    let identifier = "marker"

    var view: MKMarkerAnnotationView

    if let dequeuedView = 
mapView.dequeueReusableAnnotationView(withIdentifier: identifier) as? 
MKMarkerAnnotationView {

        dequeuedView.annotation = annotation

        view = dequeuedView

    } else {

        view = MKMarkerAnnotationView(annotation: annotation, 
reuseIdentifier: identifier)

        view.canShowCallout = true

        view.calloutOffset = CGPoint(x: -5, y: 5)

        // Broke up the button initialisation so that it has unique id 'button'
        let button = UIButton(type: .detailDisclosure)

        view.rightCalloutAccessoryView = button

        // Make the segue happen - tried to make it happen when object 'button' is pressed

        performSegue(withIdentifier: "MapDetail", sender: button)

    }

    return view
}

这是我在做的一个老项目的摘录。当点击注释上的信息附件时,它会打开一个新的tableview控制器。我创建了一个名为Annotation的自定义类,它保存了有关注释的所有信息。我不确定这是否有帮助:)

func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView,
            calloutAccessoryControlTapped control: UIControl) {

        let annotation = view.annotation as! Annotation
        let event = annotation.event

        if control == view.rightCalloutAccessoryView {
            let destination = self.storyboard!.instantiateViewController(withIdentifier: "EventViewController") as! EventViewController
            self.navigationController!.pushViewController(destination, animated: true)
            destination.event = event
    }
}
