I solved it myself.You have to set its 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;
     }
 }];
