Question

I have a map view and there are 10 store locations which data comes via webservice. I just want to push to my detail view to show address, telephone and other informations of the clicked store.

I need to pass data to my detailview when user tapped or touch up inside to a annotation on mapkit. There are 10 annotations in my mapview and first I want to know, how can I understand or how can I get the annotationID of which annotation is clicked?

this is the method I return pins

 - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{

    if ([annotation isKindOfClass:[MKUserLocation class]]) return nil;

    static NSString* AnnotationIdentifier = @"AnnotationIdentifier";

    MKPinAnnotationView* pinView = [[MKPinAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:AnnotationIdentifier];

     pinView.animatesDrop=YES;
     pinView.canShowCallout=YES;
     pinView.pinColor=MKPinAnnotationColorPurple;

     UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
     [rightButton setTitle:annotation.title forState:UIControlStateNormal];

     [rightButton addTarget:self
     action:@selector(showDetails:)
     forControlEvents:UIControlEventTouchUpInside];

     pinView.rightCalloutAccessoryView = rightButton;

    return pinView;
}
   /* and my action method for clicked or tapped annotation: */

 - (IBAction)showDetails:(id)sender{

      NSLog(@"Annotation Click");

      [[mtMap selectedAnnotations]objectAtIndex:0];
      magazaDetayViewController *detail = [[magazaDetayViewController 
      alloc]initWithNibName:@"magazaDetayViewController" bundle:nil];

      detail.sehir=@"";
      detail.magazaAdi=@"";
      detail.adres=@"";
      detail.telefon=@"";
      detail.fax=@"";
      [self.navigationController pushViewController:detail animated:YES];

 }

if i can just get the clicked annotation index no i can fill detail properties with my array.
if this is impossible is there any other way to do it?

Answer 1

First in your annotaion view delegat make a button to go in detail view like bellow:

-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation{

MKPinAnnotationView *mypin = [[MKPinAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:@"current"];
mypin.pinColor = MKPinAnnotationColorPurple;
mypin.backgroundColor = [UIColor clearColor];
UIButton *goToDetail = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
mypin.rightCalloutAccessoryView = myBtn;
mypin.draggable = NO;
mypin.highlighted = YES;
mypin.animatesDrop = TRUE;
mypin.canShowCallout = YES;
return mypin;
}

Now use the following delegate whenever the button in annotationView will get tapped the following delegate will be called from where you can easly get which particular annotaion’s button is tapped

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view 
 calloutAccessoryControlTapped:(UIControl *)control
{
annotation *annView = view.annotation;
detailedViewOfList *detailView = [[detailedViewOfList alloc]init];
detailView.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
detailView.address = annView.address;
detailView.phoneNumber = annView.phonenumber;
[self presentModalViewController:detailView animated:YES];
}

here annotaion is a class importing MKAnnotaion.h and address and phonenumber are properties of annotaion class you can make many more while the address and phoneNumber properties of detailView class are strong. So that you can pass values. Hope this will help you!
