如何跟踪单击了哪个注释标注 [英] How to track which annotation callout clicked

问题描述

我正在使用以下代码创建带有右侧附件按钮的注释标注

I am creating an annotation callout with right accessory button, using the following code

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

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

else {

    static NSString *AnnotationViewID = @"annotationViewID";

    MKAnnotationView *annotationView = (MKAnnotationView *)[self.mapView dequeueReusableAnnotationViewWithIdentifier:AnnotationViewID];

    if (annotationView == nil)
    {
        annotationView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID];
    }

    annotationView.image = [UIImage imageNamed:@"Mevents.png"];
    annotationView.annotation = annotation;
    annotationView.canShowCallout=YES;

    UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
    [rightButton setTitle:annotation.title forState:UIControlStateNormal];
    [rightButton addTarget:self action:@selector(showDetails:) forControlEvents:UIControlEventTouchUpInside];

    annotationView.rightCalloutAccessoryView = rightButton;

    //  UIImageView *profileIconView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"profile.png"]];
    //  pinView.leftCalloutAccessoryView = profileIconView;
    //  [profileIconView release];

    return annotationView;

}

}

如何跟踪点击了哪个注释?我想用 id 加载详细信息屏幕，然后根据该ID提取数据以显示信息.

How can I track, which annotation is clicked? I want to load the details screen with the id and fetch the data based on that id to show info.
