MKMapView: Instead of Annotation Pin, a custom view 3 answers

Hello I would like to add a dynamic display with a number in my point.

As in the picture, I already have the icons on the map.

Adding the numbers in point?

有一种方法可以定义注释视图的外观：

-(MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id<MKAnnotation>)annotation { MKPinAnnotationView *pinView = nil; if(annotation != mapView.userLocation) { pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:@"pinID"]; if ( pinView == nil ) { pinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID]; } pinView.canShowCallout = YES; pinView.animatesDrop = YES; . . . // ----------------------------------- // Add extra subviews here // ----------------------------------- UILabel *lblNumbers = [[UILabel alloc] init...]; lblNumbers.text = ....; lblNumbers.backgroundColor = [UIColor colorWithRed:0.1 Green:0.1 Blue:0.1]; // add the subview to the pinView [pinView addSubview:lblNumbers]; } return pinView; }

There's a method to define what the annotation view looks like:

-(MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id<MKAnnotation>)annotation { MKPinAnnotationView *pinView = nil; if(annotation != mapView.userLocation) { pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:@"pinID"]; if ( pinView == nil ) { pinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID]; } pinView.canShowCallout = YES; pinView.animatesDrop = YES; . . . // ----------------------------------- // Add extra subviews here // ----------------------------------- UILabel *lblNumbers = [[UILabel alloc] init...]; lblNumbers.text = ....; lblNumbers.backgroundColor = [UIColor colorWithRed:0.1 Green:0.1 Blue:0.1]; // add the subview to the pinView [pinView addSubview:lblNumbers]; } return pinView; }
