マーカーからのURLをコントローラに渡します

Question

私はIPカメラを見るためのアプリをやっていますし、カメラを地図に追加して、目的のマーカーをクリックして目的のカメラを見ることができます。私はWebcamを再現するマップとPlayerViewControllerを持っています。

各マーカーはウェブカメラの最初のストリームのみを送信します。助けて。別のWebカメラを動作させるにはどうすればいいですか？あなたのモデルクラスで、このプロトコルを実装することができるように

のViewController

import UIKit 
import MapKit 

class ViewController: UIViewController, MKMapViewDelegate { 

    @IBOutlet weak var mapView: MKMapView!

PlayerViewController

Answer 1

すべてMKAnnotationの第一は、議定書で、 "カメラ"

言うことができます

import UIKit 
import MapKit 

class Camera: NSObject, MKAnnotation { 

    var name: String = "" 
    var urlString :String = "" 
    var coordinate: CLLocationCoordinate2D = CLLocationCoordinate2D(latitude: 0, longitude: 0) 
    var imageName : String = "" 

    init(name:String,camUrl:String,imageNamed:String,latitude:CLLocationDegrees,longitude:CLLocationDegrees) { 
     super.init() 
     self.name = name 
     self.urlString = camUrl 
     self.imageName = imageNamed 

     guard latitude != 0 && longitude != 0 else 
     { 
      return 
     } 

     guard latitude.isNaN || longitude.isNaN else 
     { 
      return 
     } 

     self.coordinate = CLLocationCoordinate2D(latitude: latitude, longitude: longitude) 
    } 

    // Title and subtitle for use by selection UI. 
    public var title: String? { 
     get{ 
      return self.name 
     } 
    } 

} 

そして、あなたはこの

import UIKit 
import MapKit 

class ViewController: UIViewController { 

    @IBOutlet weak var mapView: MKMapView! 
    var moscow: [Camera] = [] 
    override func viewDidLoad() { 
     super.viewDidLoad() 
     // Do any additional setup after loading the view, typically from a nib. 

     self.moscow = [Camera(name: "cam1", camUrl: "http://example/1.m3u8", imageNamed: "1.jpg", latitude: 55.753989, longitude: 37.620235), 
         Camera(name: "cam2", camUrl: "http://example/2.m3u8", imageNamed: "2.jpg", latitude: 55.741308, longitude: 37.653914), 
         Camera(name: "cam3", camUrl: "http://example/3.m3u8", imageNamed: "3.jpg", latitude: 55.742468, longitude: 37.629292)] 

     self.mapView.addAnnotations(self.moscow) 
     self.mapView.delegate = self 
    } 

    override func didReceiveMemoryWarning() { 
     super.didReceiveMemoryWarning() 
     // Dispose of any resources that can be recreated. 
    } 


} 

extension ViewController : MKMapViewDelegate 
{ 
    func mapView(_ mapView: MKMapView, regionWillChangeAnimated animated: Bool) { 
     print(#function) 
    } 

    // Called when the annotation was added 
    func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? { 
     if annotation is MKUserLocation { 
      return nil 
     } 

     let reuseId = "pin" 
     var pinView = mapView.dequeueReusableAnnotationView(withIdentifier: reuseId) as? MKPinAnnotationView 
     if pinView == nil { 
      pinView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseId) 
      pinView?.animatesDrop = true 
      pinView?.canShowCallout = true 
      pinView?.isDraggable = true 
      pinView?.pinColor = .purple 

      let rightButton: AnyObject! = UIButton(type: UIButtonType.detailDisclosure) 
      pinView?.rightCalloutAccessoryView = rightButton as? UIView 
     } else { 
      pinView?.annotation = annotation 
     } 

     return pinView 
    } 

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

     let camera = view.annotation as! Camera 
     if control == view.rightCalloutAccessoryView { 
      performSegue(withIdentifier: "toTheMoon", sender: camera) 
     } 
    } 

    override func prepare(for segue: UIStoryboardSegue, sender: Any?) { 
     if segue.identifier == "toTheMoon" { 
      let controller = segue.destination as! PlayerViewController 

      controller.webcamURL = (sender as! Camera).urlString 
      controller.webcamTitle = (sender as! Camera).name 
     } 
    } 

    func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView, didChange newState: MKAnnotationViewDragState, fromOldState oldState: MKAnnotationViewDragState) { 
     if newState == MKAnnotationViewDragState.ending { 
      let droppedAt = view.annotation?.coordinate 
      print(droppedAt) 
     } 
    } 

}
