如何在我的 Pin 注释上显示标题并使其可单击以执行某些操作？

在我的 MapView 中，我在某些位置放置了图钉，现在我想在这些图钉注释上显示一些标题并使其可单击，以便单击时我可以推送另一个视图。 请帮忙 ！！！！

这是代码片段：

使用此方法的自定义注释视图

- (MKAnnotationView *)mapView:(MKMapView *)map viewForAnnotation:(id <MKAnnotation>)annotation
{
    if (annotation == mapView.userLocation) return nil;

    MKPinAnnotationView *pin = (MKPinAnnotationView *) [mapView dequeueReusableAnnotationViewWithIdentifier: @"asdf"];
    if (pin == nil)
    {
        pin = [[[MKPinAnnotationView alloc] initWithAnnotation: annotation reuseIdentifier: @"asdf"] autorelease];
    }
    else
    {
        pin.annotation = annotation;
    }
    pin.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
    pin.pinColor = MKPinAnnotationColorRed;
    pin.animatesDrop = YES;
    [pin setEnabled:YES];
    [pin setCanShowCallout:YES];
    return pin;

}

点击按钮时调用的委托方法

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{

    //DetailPg=[[BookMarksDetail alloc]initWithNibName:@"BookMarksDetail" bundle:nil];
    //DetailPg.selectRest =[view.annotation title]; //In addition, to get the Title of the AnnotationView.
    //DetailPg.m=1;
    //[self.navigationController pushViewController:DetailPg animated:YES];
    //[DetailPg release];

}
