将数据从一个视图控制器传递到同一视图上的另一个视图控制器

Question

I'm building my first app and I have two view controllers being displayed at the same time . The first is my google maps and top on of that view is a panel(pod) I found . The Googlemaps viewcontroller calls up the panel which is in a separate story board.

I'd like to be able to pass data to the panel view without having to use a segue. I have tried the segue approach but it totally replaces the whole view. Is there a way for me to pass Data to the panel without having to switch to that view alone?

extension MapViewController: GMSMapViewDelegate {
     func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool {

        guard let placeMarker = marker as? PlaceMarker else {return false}


        guard let panview = self.storyboard?.instantiateViewController(withIdentifier: "atminfo") as? PanelMaterial
        else {
            return false
        }


        panview.Titlee = placeMarker.place.name
        atmaddress = panview.Titlee ?? "Me"
        print(atmaddress)

        return false



  }

}

Above is my code, this is one the GoogleMaps ViewController, this is where I receive the info from the pin and try pass it to the Panel that is active in the same view. I'm able to receive the data when I put breakpoints, but passing the data whilst the panel is still active in my GoogleMaps View doesn't display.

Any help is appreciated.

Answer 1

you can also use singleton classes to passing the data to different controller or you can create object in appdelegate it can also used from any class.

like this:

Declare variable in appdelegate

var channelID = ""

you can use like

let kAppDelegate = UIApplication.shared.delegate as! AppDelegate
print(kAppDelegate.channelID)
