EXC_BAD_ACCESS con MKPinAnnotationView
Tengo un problema para mostrar mi MKPinAnnotationView en mapView en iOS. Recibo este error pero no entiendo de dónde proviene el error: "EXC_BAD_ACCESS". Mi código parece bueno:
-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
MKPinAnnotationView *pv = [[MKPinAnnotationView alloc] init];
[pv setPinColor:MKPinAnnotationColorGreen];
[pv setCanShowCallout:YES];
[pv setRightCalloutAccessoryView:[UIButton buttonWithType:UIButtonTypeDetailDisclosure]];
return pv;
}
Cuando configuro puntos de interrupción para la aplicación, aquí está la pantalla de mi consola usando gdb:
continue
Current language: auto; currently objective-c
Program received signal: “EXC_BAD_ACCESS”.

El error está en la segunda línea del código. ¿Cualquier sugerencia
Gracias por tu ayud
