您可以使用mapview的ViewForAnnotation方法,如下所示

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
    MKAnnotationView *annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"loc"];
    annotationView.canShowCallout = YES;
    annotationView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];

    return annotationView;
}

您还可以添加呼叫附件视图的方法

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
    [self performSegueWithIdentifier:@"DetailsIphone" sender:view];
}

这样您就可以在信息按钮上导航到方向.

更新了Swift代码

func mapView(mapView: MKMapView!, annotationView view: MKAnnotationView!, 
             calloutAccessoryControlTapped control: UIControl!) {

    if control == view.rightCalloutAccessoryView {
        println("Disclosure Pressed! \(view.annotation.subtitle)"
    }

}

你可以用它来快速语言.

请为viewforAnnotation添加此代码:

func mapView(mapView: MKMapView!, viewForAnnotation annotation: MKAnnotation!) -> MKAnnotationView! {
        if !(annotation is CustomPointAnnotation) {
            return nil
        }

        let reuseId = "test"

        var anView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseId)
        if anView == nil {
            anView = MKAnnotationView(annotation: annotation, reuseIdentifier: reuseId)
            anView.canShowCallout = true

            anView.rightCalloutAccessoryView = UIButton.buttonWithType(.InfoDark) as UIButton

        }
        else {
            anView.annotation = annotation
        }



        let cpa = annotation as CustomPointAnnotation
        anView.image = UIImage(named:cpa.imageName)

        return anView
    }

确保你已经添加了"MKMapViewDelegate"
