我按了什么CallOut？

Question

如果我在地图视图…中有很多注记如何理解我按下的CallOut？例如，在tableview中我们有"didSelectRowAtIndexPath"...但是在这里呢？

-(void)button:(id)sender {


[self performSegueWithIdentifier: @"dettaglio"sender: self];

}

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

if (![[segue identifier] isEqualToString:@"dettaglio"]&&![[segue identifier]     
isEqualToString:@"cerca"])
{

[(paginaOpzioni*)segue.destinationViewController setDelegate:self];

}

if ([[segue identifier] isEqualToString:@"dettaglio"])
{
    paginaDettaglio *ibcVC = [segue destinationViewController];
    Annotazione *annotazioneDaPassare=[mapAnnotations objectAtIndex:2];
    ibcVC.immagine = annotazioneDaPassare.immagine;
    ibcVC.navigationItem.title = annotazioneDaPassare.title;
}
}

我需要更改mapAnnotations objectAtIndex:2的值(2)；因为我想向DestinationViewController发送正确的图像和文本！谢谢

当调用-mapView:didSelectAnnotationView时，MKMapViewDelegate会告诉您选择了什么：

当然除非你指的是被窃听的配件。那就是-mapView:annotationView:calloutAccessoryTapped：
