  [nsurlconnection sendasynchronousrequest:request                                        queue:[nsoperationqueue mainqueue]   completionhandler:^(nsurlresponse *response, nsdata *data, nserror *error) {   nsstring * serveroutput= [[nsstring alloc]initwithdata:data encoding:nsasciistringencoding];   nslog(@"%@",serveroutput);          if(serveroutput!=null)               {                  if([serveroutput isequaltostring:@"login"])                      {                            [self getdetails];                            [self performseguewithidentifier:@"app" sender:self];                        }   if(app)   [self performseguewithidentifier:@"app" sender:self];   [_alertview dismisswithclickedbuttonindex:0 animated:yes];         }      } ];      _alertview = [[uialertview alloc] initwithtitle:@"please wait..."                                         message:@"\n"                                        delegate:self                               cancelbuttontitle:nil                               otherbuttontitles:nil];  uiactivityindicatorview *spinner = [[uiactivityindicatorview alloc] initwithactivityindicatorstyle:uiactivityindicatorviewstylewhitelarge];  spinner.center = cgpointmake(139.5, 75.5); [alertview addsubview:loading];  [spinner startanimating]; [alertview show];

the value of "app" yes when execute [self detail] method

try giving different id segue , view controller. clearly, must have made changes in app somewhere , forgotten it. check storyboard connection also. try deleting segue , given again.
