如何跟蹤單擊了哪個注釋標注

Question

我使用以下代碼創建帶有右側附件按鈕的注釋標注

- (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;

}

}

如何跟蹤單擊了哪個注釋 ？ 我想用ID加載詳細信息屏幕，並根據該ID獲取數據以顯示信息。

Answer 1

創建注釋時，在其中添加標簽

annotationView.image = [UIImage imageNamed:@"Mevents.png"];
//Add this after
annotationView.tag = 111;

現在在viewForAnnotation ，檢查該標簽

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

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

    if(annotation.tag == 111)
        //Do something
    else
        //Do some other thing
}
