推荐答案

这是代码段:

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;

}

代理方法，当您点击按钮时会被调用

- (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];

}
