MKPinAnnotationView标注按钮，将自定义类信息传递给Details ViewController

Question

我为餐厅创建了一个自定义类，其中包括以下信息：名称，类型，地址，坐标，照片，收藏夹菜等。我制作了MKPinAnnotations，当名称和类型通过菜单上的按钮传递时，该名称和类型会传递单击了标注，但我想传递该类实例中的所有信息。我试图创建某种填充函数，但是每次找到一个nil值并且程序中断。我是Xcode的新手，欢迎任何帮助！

func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> 
  MKAnnotationView? {
    if annotation is MKUserLocation {
        return nil
    }
    let pin = MKPinAnnotationView(annotation: annotation, 
         reuseIdentifier:  "pin")
    pin.canShowCallout = true
    pin.rightCalloutAccessoryView = UIButton(type: .detailDisclosure)
    return pin
}

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

    let annView = view.annotation

    let storyboard = UIStoryboard(name: "Main", bundle: nil)

    let detailVC = storyboard.instantiateViewController(withIdentifier: 
       "details") as! DetailViewController


    detailVC.name = ((annView?.title)!)!
    detailVC.type = ((annView?.subtitle)!)!
    detailVC.fill2()

// fill2（）是我在detailViewController中创建的函数

    self.navigationController?.pushViewController(detailVC, animated: 
       true)

}

DetailViewController函数：

 func fill2(){
        if detailName.text == places[0].name {
            detailFavorite.text = places[0].favorite
            detailAddress.text = places[0].address
            detailType.text = places[0].type
            detailImage.image = places[0].photo
        }
    }

欢迎任何帮助！谢谢！
