Selected map pins show the same coordinate - ios

Question

I am trying get the coordinate of each pin I select on my map. Pins are the local search results that users search on the map. I have an issue that every pin I select it give me the same value. Can anyone help me with this please? Thanks in advance.
- (IBAction)searchAction:(id)sender {
[sender resignFirstResponder];
[self.mapView removeAnnotations:[self.mapView annotations]];
[self performSearch]; }
-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation{
// If it's the user location, just return nil.
if ([annotation isKindOfClass:[MKUserLocation class]])
return nil;
MKPinAnnotationView *mypin = [[MKPinAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:#"current"];
//mypin.pinColor = MKPinAnnotationColorPurple;
mypin.backgroundColor = [UIColor clearColor];
UIButton *goToDetail = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
mypin.rightCalloutAccessoryView = goToDetail;
mypin.draggable = NO;
mypin.highlighted = YES;
mypin.animatesDrop = TRUE;
mypin.canShowCallout = YES;
return mypin;
}
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
MKPointAnnotation *annotation = view.annotation;
self.tappedCoord = annotation.coordinate;
// Longs are the same for every pin I select
NSLog(#"%f", [[view annotation] coordinate].longitude);
}
- (void)performSearch {
MKLocalSearchRequest *request = [[MKLocalSearchRequest alloc] init];
request.naturalLanguageQuery = _searchText.text;
request.region = _mapView.region;
self.matchingItems = [[NSMutableArray alloc] init];
MKLocalSearch *search = [[MKLocalSearch alloc]initWithRequest:request];
[search startWithCompletionHandler:^(MKLocalSearchResponse *response, NSError *error) {
if (response.mapItems.count == 0)
NSLog(#"No Matches");
else
for (MKMapItem *item in response.mapItems)
{
[self.matchingItems addObject:item];
MKPointAnnotation *annotation = [[MKPointAnnotation alloc]init];
annotation.coordinate = item.placemark.coordinate;
annotation.title = item.name;
annotation.subtitle = [NSString stringWithFormat:#"%#, %# %#",
item.placemark.addressDictionary[#"Street"],
item.placemark.addressDictionary[#"State"],
item.placemark.addressDictionary[#"ZIP"]];
//NSLog(#"%#", item.placemark.addressDictionary);
[_mapView addAnnotation:annotation];
}
}];
