IOS: mapkit scaling for two annotation points

Question

I want to know if there is a way to have dynamic scaling when I set the blue dot (my position) in my map view and another output ... when I load mapview, I want to show these two points in the same frame ... maybe ? thanks

Answer 1

Yes it is possible. After adding the second annotation. This sample code should work for any number of annotations:

MKMapRect zoomRect = MKMapRectNull; NSArray *annotations = [mapView annotations]; for (MKAnnotation *annotation in annotations) { MKMapPoint annotationPoint = MKMapPointForCoordinate(annotation.coordinate); MKMapRect pointRect = MKMapRectMake(annotationPoint.x, annotationPoint.y, 0, 0); if (MKMapRectIsNull(zoomRect)) { zoomRect = pointRect; } else { zoomRect = MKMapRectUnion(zoomRect, pointRect); } } [mapView setVisibleMapRect:zoomRect animated:YES];
