Ios 从calloutAccessoryControlTapped设置ViewController标题

我试图简单地将detailViewController的标题设置为点击呼叫附件控件后的pin标题

这里是我设置MKAnnotation的地方：

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id 
<MKAnnotation>)annotation
{
MKAnnotationView *annotationView = [[MKPinAnnotationView alloc] 
initWithAnnotation:annotation reuseIdentifier:@"loc"];

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

DetailViewController *controller = [[DetailViewController alloc] initWithNibName:nil
                                                                            bundle:nil];
[self.navigationController pushViewController:controller animated:YES]; // or use     
presentViewController if you're using modals

controller.title = pin.annotationView.subtitle;

}

最后一行是乱七八糟的。有什么想法吗？谢谢大家

找到答案-将控制器标题替换为：

controller.title = view.annotation.title;

controller.title = view.annotation.title;

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view     
calloutAccessoryControlTapped:(UIControl *)control
{
MKAnnotation * annotation = (MKAnnotation *)annotation;

DetailViewController *controller = [[DetailViewController alloc] initWithNibName:nil
                                                                            bundle:nil];
controller.title = annotation.subtitle;

[self.navigationController pushViewController:controller animated:YES]; // or use
