mapkit默认显示注解

问题描述

我在mapkit显示具有自定义图像注释，显示细腻，

I have an annotation showing in mapkit with a custom image, showing fine,

但注释显示录音针后，

我怎么能在默认情况下？注释显示，当我开始的看法？白衣出攻针。

how can I have the annotation showing by default?, when I start the view? whit out tapping the pin.

- (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; 

}

推荐答案

您可以使用此

[图形页面selectAnnotation：pinView动画：是]; //这里pinView是你的注释和图形页面是你的地图

[mapView selectAnnotation:pinView animated:YES]; //here pinView is your annotation and mapview is your map
