i solved myself.you have set completion using following code.

just add following code after presenting controller

[controllerslc setcompletionhandler:^  (slcomposeviewcontrollerresult result) {       [[nsnotificationcenter defaultcenter]postnotificationname:@"hidenotification" object:nil];       nsstring *output = [[nsstring alloc] init];        switch (result) {          case slcomposeviewcontrollerresultcancelled:              output = @"post cancelled";              break;          case slcomposeviewcontrollerresultdone:              output = @"posted successfully";              break;           default:              break;      }  }];
