calloutAccessoryControlTapped未在storyboard中调用

Question

我有一个包含MKMapView的视图,我在其中显示了sereval引脚:

- (MKAnnotationView *)mapView:(MKMapView *)theMapView viewForAnnotation:(id <MKAnnotation>)annotation
{
  NSLog(@"mapView:viewForAnnotation");

  // if it's the user location, just return nil.
  if ([annotation isKindOfClass:[MKUserLocation class]]){
      return nil;
  }

  static NSString* AnnotationIdentifier = @"AnnotationIdentifier";
  MKPinAnnotationView *pinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationIdentifier];
  pinView.canShowCallout = YES;
  pinView.pinColor = MKPinAnnotationColorPurple;
  pinView.annotation = annotation;    

  return pinView;
}

这工作正常,但方法:

-(void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control

单击引脚时不会调用.似乎点击事件没有传输到引脚,但我无法弄清楚原因.任何的想法 ？

Answer 1

单击引脚本身时,地图视图将调用委托方法mapView:didSelectAnnotationView:.

calloutAccessoryControlTapped在注释视图leftCalloutAccessoryView或被rightCalloutAccessoryView点击时调用该方法.这些是引脚标注上显示的控件(通常是按钮).

听起来你正在寻找mapView:didSelectAnnotationView:委托方法.
