ios - 在UIButton的选择器上传递参数

Question

我在detailDisclousure的标注上有一个MKAnnotation按钮。当按下此按钮时，我需要调用一个传递参数的方法，该参数标识调用它的annotation。怎么做？

这是我的viewForAnnotation:

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{

if ([annotation isKindOfClass:[Annotation class]])
{
    static NSString* identifier = @"identifier";

    MKPinAnnotationView* pinView = (MKPinAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:identifier];

    if (pinView == nil) 
    {
        pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier]autorelease];
    }

    Annotation *antt = annotation;

    pinView.canShowCallout = YES;
    pinView.draggable =    YES;

    UIButton* detailButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];

    [detailButton performSelector:@selector(goToViewWithAnnotation:) withObject:antt];

    pinView.rightCalloutAccessoryView = detailButton;

    return pinView;
}

else 
{
    return nil; 
}
}

这是应该使用参数调用的方法:

-(void)goToViewWithAnnotation:(Annotation *)annotation
{
    NextViewController *nextView = [[NextViewController alloc]initWithNibName:@"NextViewController" bundle:nil];

nextView.id = annotation.id;

[self.navigationController nextView animated:YES];
}

您只能通过NSInteger的tag属性传递任何UIButton。
