通过序列将数据从地图标注中的detailDisclosure按钮传递到新的DetailView

我使用JSON文件在MapView上填充了几个pin。每个插脚都正确显示一个带有标题、副标题、图像和详细信息披露按钮的标注。

我试图在地图视图和细节视图(安排为表视图)之间创建一个分段,这样当用户单击detailDisclosure按钮时,他们就会进入细节视图屏幕。

我创建的segue工作得很好,但是,我不知道如何传递数据。我如何才能成功地将数据传递到此序列,使其显示在细节视图中?请参阅下面的相关代码。

func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) {
    self.performSegue(withIdentifier: "toShowLocationDetail", sender: self)
}

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "toShowLocationDetail" {
        // I DON'T KNOW WHAT TO PUT IN HERE - I THINK THIS IS WHERE THE INFORMATION ABOUT THE DATA GOES
    }
}

我不确定您是否需要它,但这是我的ViewDidLoad方法(我用于解析JSON文件并填充注释:

var locations = [Location]()

override func viewDidLoad() {
    super.viewDidLoad()

    // parse json
    if let locationJson = readLocation(){
        if let locationArray = locationJson["locations"] as? [[String:Any]]{
            for location in locationArray{
                locations.append(Location.init(locationInfo: location))
            }
            print(locations.count)
        }
    }
    // end parse json

    nearMeMap.delegate = self

    self.locationManager.delegate = self
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
    self.locationManager.requestWhenInUseAuthorization()
    self.locationManager.startUpdatingLocation()
    self.nearMeMap.showsUserLocation = true


    // Show annotation
    for location in locations {
        let annotation = MKPointAnnotation()
        annotation.title = location.name
        annotation.subtitle = location.type
        annotation.coordinate = CLLocationCoordinate2D(latitude: location.latitude, longitude: location.longitude)
        self.nearMeMap.addAnnotation(annotation)

    }

}

DetailView中的变量集(当前使其能够显示TableView中的数据)为:

var location:Location!

编辑:

class Location: NSObject {
    var id: String = ""
    var name: String = ""
    var type: String = ""
    var location: String = ""
    var image: String = ""
    var activity: String = ""
    var isVisited: Bool = false
    var rating: String = ""
    var latitude: Double = 0.0
    var longitude: Double = 0.0

    init(locationInfo:[String:Any]) {
        self.id = locationInfo["id"] as! String
        self.name = locationInfo["name"] as! String
        self.type = locationInfo["type"] as! String
        self.location = locationInfo["location"] as! String
        self.image = locationInfo["image"] as! String
        self.activity = locationInfo["activity"] as! String
        self.isVisited = locationInfo["isVisited"] as! Bool
        self.latitude = locationInfo["latitude"] as! Double
        self.longitude = locationInfo["longitude"] as! Double
    }

    public var coordinate: CLLocationCoordinate2D { get {
        let coordinate = CLLocationCoordinate2D(latitude: latitude, longitude: longitude)
        return coordinate
        }
    }

}
