I want to have a custom MKAnnotationView. I've created a xib file in IB and set its class to MyAnnotationView.
class MyAnnotationView: MKAnnotationView {
override init(annotation: MKAnnotation?, reuseIdentifier: String?) {
super.init(annotation: annotation, reuseIdentifier: reuseIdentifier)
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
@IBOutlet weak var textLabel: UILabel!
@IBOutlet weak var busIcon: UIImageView!
}
Here's how the xib looks like - it has a textLabel and a busIcon linked:
I'm using the viewFor annotation delegate method to create views for all annotations:
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
// Don't want to show a custom image if the annotation is the user's location.
if (annotation is MKUserLocation) {
return nil
} else {
let annotationIdentifier = "AnnotationIdentifier"
var annotationView: MyAnnotationView?
if let dequeuedAnnotationView = mapView.dequeueReusableAnnotationView(withIdentifier: "AnnotationIdentifier") as? MyAnnotationView {
annotationView = dequeuedAnnotationView
annotationView?.annotation = annotation
} else {
// if no views to dequeue, create an Annotation View
let av = MyAnnotationView(annotation: annotation, reuseIdentifier: annotationIdentifier)
av.rightCalloutAccessoryView = UIButton(type: .detailDisclosure)
annotationView = av
}
if let annotationView = annotationView {
annotationView.canShowCallout = true // callout bubble
annotationView.image = UIImage(named: "Delivery")
annotationView.frame = CGRect(x: 0, y: 0, width: 40, height: 40)
}
return annotationView
}
}
The annotationView.image = UIImage(named: "Delivery")
&
AnnotationView.frame = CGRect(x: 0, y: 0, width: 40, height: 40)
are there just to check if the code is working and display a sample view on the map, as they use the standard properties inherited from MKAnnotationView.
I don't know how to make the viewFor annotation method use the XIB I have created. Could anyone please help me with that? I searched for the solution, but only found something relevant in Obj C.
Thank you!
