点击后如何在注释上居中或重新定位Mapbox地图？

Question

Is there a way to center a Mapbox map onto an annotation after it's been tapped? Or is there a way to reposition the map after an annotation has been opened when the callout view (custom, in this case) is not entirely in view?

Answer 1

You can center a map view on an annotation by setting the map view's center coordinate to the coordinate of the annotation in -mapView:didSelectAnnotation: . If you are using annotation views, another option is to set the map view's center coordinate in -mapView:didSelectAnnotationView: .

For example: - (void)mapView:(MGLMapView *)mapView didSelectAnnotation:(id<MGLAnnotation>)annotation { mapView.centerCoordinate = annotation.coordinate; } - (void)mapView:(MGLMapView *)mapView didSelectAnnotation:(id<MGLAnnotation>)annotation { mapView.centerCoordinate = annotation.coordinate; }
