mapkit默认显示注释

Question

我在mapkit中显示了一个带有自定义图像的注释，显示正常，

但是在录制针脚后显示注释

当我启动视图时，如何在默认情况下显示注释？发出针脚。

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


    if([annotation isKindOfClass:[MKUserLocation class]])
        return nil; 

    NSString *annotationIdentifier = @"PinViewAnnotation"; 

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


    if (!pinView) 
    {
        pinView = [[[MKPinAnnotationView alloc] 
                    initWithAnnotation:annotation 
                    reuseIdentifier:annotationIdentifier] autorelease];

        [pinView setPinColor:MKPinAnnotationColorGreen];
        pinView.animatesDrop = YES; 
        pinView.canShowCallout = YES; 

        UIImageView *houseIconView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"tijereta.png"]];
        pinView.leftCalloutAccessoryView = houseIconView; 
        [houseIconView release];        
    }
    else 
    {
        pinView.annotation = annotation;
    }

    return pinView; 

}

你可以用这个

[mapView selectAnnotation:pinView animated:YES]; //这里pinView是你的注释，mapview是你的地图

希望有所帮助
