如何将ID从具有地图视图的视图控制器传递到另一个视图控制器？

Question

我正在使用解析来检索数据，如何将具有映射视图的viwecontroller的对象ID传递给另一个视图控制器，

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

    [self performSegueWithIdentifier:@"MapToDeal" sender:view.annotation];
    NSLog(@"%@",view.annotation.title);
}

Answer 1

在.m文件中写入此方法

- (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString: @"MapToDeal"])
  {
    DetailViewController *detailViewController = [segue destinationViewController];

    detailViewController.annotview = sender; //here annoteview is  object in DetailViewcontroller
  }
}

或者你也可以这样

In mapView Delegate method

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
    [self performSegueWithIdentifier:@"MapToDeal" sender:view];
}

In prepareForSegue:

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if([[segue identifier] isEqualToString:@"MapToDeal"])
    {
        MapPoint *annotation = (MapPoint *)view.annotation;

        DetailViewController *dvc = segue.destinationViewController;
        dvc.name = annotation.name;
        dvc.anyproperty = annotation.anyproperty;

    }
}
