ios - 传递自定义注释的数据

如何传递Custom批注的数据？我使用此功能执行segue：

func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {}

class Custom: MKPointAnnotation {
    var name: String?
    var time: String?
    var address: String?
}

最佳答案

你可以试试

func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {
    let anno = view.annotation as! Custom
    print(anno.name)
    // then access the properties of anno and use them for the segue
    self.performSegue(withIdentifier:"SegueID",sender:anno)
}

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
  if segue.identifier == "SegueID" {

    let des = segue.destination as! SecondVC
    des.ann = sender as! Custom
  }
}

class SecondVC:UIViewController {

   @IBOutlet weak var lbl:UILabel!
   var ann:Custom!
    override func viewDidLoad() {
       super.viewDidLoad()
       self.lbl.text = ann.name
     }
}
