Pass annotation title to embedded containerview when selected Swift
I have tried using the func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) to pass the annotation title to the embedded container view. However when i build and run, it doesn't work.
What am I doing incorrectly? Is this the right approach?
I've tried func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) see code
var annotationTitle = "Default"
func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView){
if let annotation = view.annotation {
annotationTitle = annotation.title!!
}
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "showMapContainer" {
let destination = segue.destination as! MapDetailContainerViewController
destination.selectedAnnotation = annotationTitle as String
}
}
}
The data is being passed to the containerviewcontroller as "Deafult" instead of annotation.title value

Thanks for the insight. The container and map are shown at the same time. I want to be able to click the various map pins and have the container show information about the pin currently selected.

You said:

If they’re both created at the same time, then prepare(for:sender:) is undoubtedly getting called before didSelect is. You can confirm that with some breakpoints or judicious print statements.
So you can have prepare(for:sender:) save a reference to segue.destination as? MapDetailContainerViewController in some local variable and then didSelect can set selectedAnnotation
var embeddedViewController: MapDetailContainerViewController?
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "showMapContainer" {
embeddedViewController = segue.destination as? MapDetailContainerViewController
}
}
func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {
if let annotation = view.annotation,
let title = annotation.title {
embeddedViewController?.selectedAnnotation = title
}
}
Or you can bypass the prepare(for:sender) and just use children (previously called childViewControllers):
func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView){
if let embeddedViewController = children.first as? MapDetailContainerViewController,
let annotation = view.annotation,
let title = annotation.title {
embeddedViewController.selectedAnnotation = title
}
}
