How to tell a rightCalloutAccessoryView has been touched for MapKit

问题

I have a MKAnnotationView being allocated with a DetailDisclosure button being displayed on the right side of the annotation. How would I go about knowing when a user clicked on the annotation button? This is what my code looks like right now -

UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
pinView.rightCalloutAccessoryView = rightButton;
pinView.animatesDrop = YES;

Is there a built in method to detect when a accessory view has been touched? I'm guessing it would be like the UITableView methods, but I can't find anything. Thanks for any help.

回答1:

You need some object to be set as your map view's delegate, and implement the MKMapViewDelegate protocol method -mapView:annotationView:calloutAccessoryControlTapped:.

回答2:

Implement mapView:annotationView:calloutAccessoryControlTapped: method in your MKMapViewDelegate.
