POHow to know which annoation has been tapped?
text
Body
copied!<p>I am doing mapview. In my app there is code which gets current location of the user in latitude and longitude. Using this coordinates i am creating a soap request. In response i will get information(zip,city,state,country,coordinates) of locations. I have saved this information in NSDictionary.</p> <p>This is the code for creating annotation.</p> <pre><code>MapLocation *annotation = [[MapLocation alloc] initWithCoordinate:location ownerInst:ownerInstitution]; [mapView addAnnotation:annotation]; [annotation release]; - (MKAnnotationView *) mapView:(MKMapView *)theMapView viewForAnnotation:(id <MKAnnotation>) annotation { MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentloc"]; annView.pinColor = MKPinAnnotationColorGreen; annView.animatesDrop=TRUE; annView.canShowCallout = YES; UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; [infoButton addTarget:self action:@selector(infoButtonPressed) forControlEvents:UIControlEventTouchUpInside]; annView.rightCalloutAccessoryView = infoButton; annView.calloutOffset = CGPointMake(-5, 5); return annView; } </code></pre> <p>This is the delegate method when user tap the detaildisclosurebutton in the callout.</p> <pre><code>- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control </code></pre> <p>On the tap of detail disclosure button new view will be loaded. And in this new view, information which i retrieved from the server will be displayed.</p> <p>Upto this everything is fine. I have more than one annotations in the map. But when particular annotation is tapped how will i implement the code to show the information (which i get from the server)related to that annotation.</p> <p>I hope I am clear in expressing my problem. Feel free to ask further details.</p>
