mkannotation自动/默认标注未发生

Question

我添加了一个注释，在viewforannotation中我设置了canshowcallout并选择了注释，但它没有被选中......

  -(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{
    currentCoordinates = newLocation.coordinate;
 ParkPlaceMark *pa = [[ParkPlaceMark alloc] init];
        pa.coordinate = currentCoordinates;
        pa.title = @"POI";
        pa.title2 = @"CUrrent Locn";
        pa.subtitle = @"Drag and drop to adjust the position if necessary";
        [mapView addAnnotation:pa];
        [pa release];
   }
   - (MKAnnotationView *)mapView:(MKMapView *)map
        viewForAnnotation:(ParkPlaceMark*)annotation {

MKAnnotationView *test=[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"parkingloc"];
if([annotation.title caseInsensitiveCompare:@"POI"] == NSOrderedSame)
{
    test.annotation = annotation;

    test.userInteractionEnabled = YES;
    test.draggable = YES;
    //        test.pinColor = MKPinAnnotationColorRed;

    [test setImage:[UIImage imageNamed:@"marker3.png"]];
    [test setEnabled:YES];
    [test setCanShowCallout:YES];
    [test setDragState:MKAnnotationViewDragStateEnding animated:YES];
    [self.mapView selectAnnotation:test.annotation animated:YES];
    return test;
   }
  }

Answer 1

我添加了自定义动画

  [self.mapView selectAnnotation:test.annotation animated:YES];

无效。正确的代码是：

  [self.mapView selectAnnotation:test.annotation animated:NO];
