Question

如果我在地图视图中有很多注释...如何理解我按下了什么CallOut？例如在tableview中我们有“didSelectRowAtIndexPath”......但是在这里？

-(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字！感谢

你的MKMapViewDelegate会告诉你在调用-mapView时选择了什么：didSelectAnnotationView：

http://developer.apple.com/library/ios/documentation/MapKit/Reference/MKMapViewDelegate_Protocol/MKMapViewDelegate/MKMapViewDelegate.html#//apple_ref/occ/intfm/MKMapViewDelegate/mapView:didSelectAnnotationView：

除非您指的是被轻拍的配件。那将是-mapView：annotationView：calloutAccessoryTapped：

http://developer.apple.com/library/ios/documentation/MapKit/Reference/MKMapViewDelegate_Protocol/MKMapViewDelegate/MKMapViewDelegate.html#//apple_ref/occ/intfm/MKMapViewDelegate/mapView:annotationView:calloutAccessoryControlTapped：

我压了什么CallOut？
