How to find which annotation send 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:)
开发者_C百科 forControlEvents:UIControlEventTouchUpInside];
customPinView.rightCalloutAccessoryView = rightButton;
return customPinView;
- (void)showDetails:(id)sender
{
some code
}
The comments in your code have the answer. Instead of using a custom method and calling addTarget, use the map view's calloutAccessoryControlTapped delegate method. In this method, you will get a reference to the annotation view which contains a reference to the annotation.
Remove the call to addTarget and replace your "showDetails" method with:
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view
calloutAccessoryControlTapped:(UIControl *)control
{
MyAnnotationClass *annot = (MyAnnotationClass *)view.annotation;
//do something...
}
