ios - not able to tap on MKPinAnnotationView Second Time -

i have created custom annotation using code.

    - (mkannotationview *)mapview:(mkmapview *)mapview viewforannotation:(id<mkannotation>)annotation     {         static nsstring *const annotatioviewreuseid = @"annotatioviewreuseid";        // mkannotationview          mkpinannotationview *annotationview = (mkpinannotationview *)[mapview dequeuereusableannotationviewwithidentifier:annotatioviewreuseid];

and in didselect method have written code present view controller

 - (void)mapview:(mkmapview *)mapview didselectannotationview:(mkannotationview *)view     {         nslog(@"didselectannotationview");          if ([view.annotation iskindofclass:[fbannotationcluster class]]) {              nslog(@"fbannotationcluster select annotation");         }         else{               spotdetailvc *locdetailvc = [[uistoryboard storyboardwithname:@"spotdetail" bundle:nil] instantiateviewcontrollerwithidentifier:@"spotdetailvc"];              [self presentviewcontroller:navcontroller animated:yes completion:nil];         }     } 

now when click on annotation first time works after dismiss view again click on same annotation not works.

please help, know it's silly mistake not able configure out one.
