mkmapview中注释引脚的自定义图像

Question

长按时自定义注释引脚更改为默认红色引脚.

  - (MKAnnotationView *) mapView:(MKMapView *)mapingView viewForAnnotation:(id <MKAnnotation>) annotation {
 MKPinAnnotationView *annView = nil;
        if(annotation != mapingView.userLocation) 
        {

            static NSString *defaultPinID = kDEFAULTPINID;
            annView = (MKPinAnnotationView *)[mapingView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
            if ( annView == nil ) 
            annView = [[MKPinAnnotationView alloc]
                                             initWithAnnotation:annotation reuseIdentifier:defaultPinID] ;


            annView.canShowCallout = YES;
            annView.image = [UIImage imageNamed:@"icon.png"];//sets image for default pin

}
return annView;
}


- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKPinAnnotationView *)view 
    { 
        if ([[view.annotation title] isEqualToString:@"AnnotationTitle"] ) {

             view.image = [UIImage imageNamed:@"selected_IconImage.png"];
       }
    }

只需触摸注释引脚即可显示所选图像.但是,长时间点击引脚自定义图像将恢复为默认红色引脚.

如何解决这个问题？

Answer 1

使用an MKAnnotationView而不是a MKPinAnnotationView,我猜测地图视图会执行某种重置,然后返回默认图像(这是您看到的图像)
