Show annotation title automatically

Question

I'm trying to display the annotation title automatically instead of displaying it on tap. I used the below code to display annotation and make it center on map.

self.ann.setCoordinate(currentLocation2D)
self.ann.title = "Title"
self.ann.subtitle = "Subtitle"
self.mapView.addAnnotation(self.ann);

self.span = MKCoordinateSpanMake(0.005, 0.005)
self.region = MKCoordinateRegion(center: currentLocation2D, span: self.span)
self.mapView.setRegion(self.region, animated: true)

I get to see the title, subtitle and CalloutAccessoryView when I tap the annotation but couldn't able to display it automatically.

Answer 1

You can use it by using selectAnnotation and use the mapview.annotations array, which contains all your annotations which you have on your map.

let yourAnnotationAtIndex = 0
mapView.selectAnnotation(mapView.annotations[yourAnnotationAtIndex], animated: true)

Answer 2

mapView.selectAnnotation(mapView.annotations[0], animated: true)
