点击当前位置的大头针有问题

[Dronaldo17]

原来写法

• (MAAnnotationView*)mapView:(MAMapView *)mapView viewForAnnotation:(id )annotation
  {
  if ([annotation isKindOfClass:[MAPointAnnotation class]])
  {
  MAPointAnnotation *pointAnnotation = (MAPointAnnotation *)annotation;
  if ([pointAnnotation.component isKindOfClass:[WXMapInfoWindowComponent class]]) {
  return [self _generateCustomInfoWindow:mapView viewForAnnotation:pointAnnotation];

    }else {
        return [self _generateAnnotationView:mapView viewForAnnotation:pointAnnotation];
    }
  

  }

  return nil;
  }

会有一个问题，当前大头针的类为 MAUserLocation，所以上述代码会崩溃，如果有开发者遇到此类问题 ，参考我一下代码

• (void)mapView:(MAMapView *)mapView didSelectAnnotationView:(MAAnnotationView *)view
  {
  MAPointAnnotation *annotation = view.annotation;
  for (WXComponent *component in self.subcomponents) {
  if ([component isKindOfClass:[WXMapViewMarkerComponent class]]) {

        if ([annotation isKindOfClass:[MAUserLocation class]]) {
            
        }
    
        else if (annotation.component) {
            if ([component.ref isEqualToString:annotation.component.ref]) {
                WXMapViewMarkerComponent *marker = (WXMapViewMarkerComponent *)component;
                if (marker.clickEvent) {
                    [marker fireEvent:marker.clickEvent params:[NSDictionary dictionary]];
                }
  
            }
        }
        else{
        
        }
     }
  

  }
  }
