如何找到哪个注释发送showDetails?
MKPinAnnotationView* customPinView = [[[MKPinAnnotationView alloc]
initWithAnnotation:annotation reuseIdentifier:BridgeAnnotationIdentifier] autorelease];
customPinView.pinColor = MKPinAnnotationColorPurple;
customPinView.animatesDrop = YES;
customPinView.canShowCallout = YES;
// add a detail disclosure button to the callout which will open a new view controller page
//
// note: you can assign a specific call out accessory view, or as MKMapViewDelegate you can implement:
// - (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control;
//
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton addTarget:self
action:@selector(showDetails:)
forControlEvents:UIControlEventTouchUpInside];
customPinView.rightCalloutAccessoryView = rightButton;
return customPinView;
- (void)showDetails:(id)sender
{

代码中的注释有答案。不使用自定义方法并调用addTarget,而是使用map视图的calloutAccessoryControlTapped委托方法。在此方法中,您将获得对注释视图的引用,该注释视图包含对注释的引用。
删除对addTarget的调用,并将“showDetails”方法替换为:
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view
calloutAccessoryControlTapped:(UIControl *)control
{
MyAnnotationClass *annot = (MyAnnotationClass *)view.annotation;
//do something...
}
