                         for (CLPlacemark* aPlacemark in placemarks1)
                         {
                             annotationCoord=  aPlacemark.location.coordinate;
                             [locationManager stopUpdatingLocation];
                             MKCoordinateRegion region;
                             region.center.latitude=annotationCoord.latitude;
                             region.center.longitude=annotationCoord.longitude;

                             region.span.longitudeDelta=0.;
                             region.span.latitudeDelta=0.;


                             self.mapView.showsUserLocation = YES;
                             [self.mapView setRegion:region];
                             _annotation=[[LDAnnotation alloc]initWithCoordinate:annotationCoord andTitle:@""subTitle:@""];
                             [self.mapView addAnnotation:(id<MKAnnotation>)_annotation];
                             [_searchAddressTF resignFirstResponder];
                         }
                     }];

your placemarks1 array is probably empty, as you're not checking if it is or not, the block just isn't executing. This is the common format

[self.geocoder geocodeAddressString:address completionHandler:^(NSArray *placemarks, NSError *error) {
    if ([placemarks count] > 0) {
        CLPlacemark *placemark = [placemarks objectAtIndex:0];
        CLLocation *location = placemark.location;
        CLLocationCoordinate2D coordinate = location.coordinate;

you can try printing the size of the place marks. Check out this page if you haven't seen it already. http://code.tutsplus.com/tutorials/forward-geocoding-with-clgeocoder--mobile-11011
