How to add colored border bubble callout in swift?

Question

I added a right button to callout, but now I'd like add a colored border to the whole bubble/callout. let's say I want the whole bubble with a colored border. I thought to implement something as view?.detailCalloutAccessoryView?.layer.borderWidth = 5.0 view?.detailCalloutAccessoryView?.layer.borderColor = UIColor(red:51/255.0, green:153/255.0, blue:255/255.0, alpha: 1.0).CGColor but it doesn't work

something similar to this (I know that here they only aded a red view) but white inside, but with a colored border

 //MARK: this is for adding info button to pins on map 1/2
    func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
        var view = mapView.dequeueReusableAnnotationViewWithIdentifier("AnnotationView Id")

        if view == nil{
            view = MKPinAnnotationView(annotation: annotation, reuseIdentifier: "AnnotationView Id")
            view!.canShowCallout = true
        } else {
            view!.annotation = annotation
        }
        //is this right?
        view?.rightCalloutAccessoryView = UIButton(type: UIButtonType.DetailDisclosure)
        view?.rightCalloutAccessoryView?.layer.borderColor = UIColor(red:222/255.0, green:225/255.0, blue:227/255.0, alpha: 1.0).CGColor

        return view
    }

    //MARK: this is for adding info button to pins on map 2/2
    func mapView(mapView: MKMapView, annotationView view: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) {

        if (control as? UIButton)?.buttonType == UIButtonType.DetailDisclosure {

            let annotation = view.annotation as! MyMKPA
            self.userToPass = annotation.pointAnnotationPFUser
            mapView.deselectAnnotation(view.annotation, animated: false)
            performSegueWithIdentifier("fromMapToDetail", sender: view) 
        }
    }

Shithead

The answer you took this from included a link to a project that does this. github.com/robertmryan/CustomMapViewAnnotationCalloutSwift Did you look at that? In answer to your question, there is no obvious way to doing this the preferred technique of using detailCalloutAccessoryView, so you have to do this yourself, methinks. It seems like there should be some appearance mechanism to set the background color of the bubble, but I haven't found it. – Odie

I'm still studying your project (I'm pretty new to iOS) but it seems clear that I can't simply subclass the callout and then call it via dot notation on view! or missing some annotation property in viewForAnntation right? – Shithead

Sadly, I think you have to completely create your own callout to get this sort of look at feel. Personally, I'd recommend forgoing the complexity of all of this and just use detailCalloutAccessoryView and live with the limitation of the white background. – Odie
