UISearchController's UISearchDisplayController not showing

Question

Couple of months ago I asked a question to show the UISearchDisplayController and it worked like a charm but

Now I am presenting another controller after user taps on the searchResultsController's tableview cell and it selects a cell and hides the searchResultsController to show MapView but once you tap the search bar searchResultsController doesn't shows up but once you press cancel button and tap search bar again it starts working again.

Scenario is exactly the Apple's Maps app opening up favourite view along with recent view controller with segments.

Here's my code for UISearchControllerDelegate:

- (void)willPresentSearchController:(UISearchController *)searchController
{
    mainViewController *__weak weakSelf=self;
    dispatch_async(dispatch_get_main_queue(), ^{
        mainViewController *__strong strongSelf = weakSelf;
        strongSelf.searchController.searchResultsController.view.hidden = NO;
    });
}

- (void)didPresentSearchController:(UISearchController *)searchController
{
    self.searchController.searchResultsController.view.hidden = NO;
}

And here is my code for UISearchBarDelegate.

- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar{

    mainViewController *__weak weakSelf=self;
    dispatch_async(dispatch_get_main_queue(), ^{
        mainViewController *__strong strongSelf = weakSelf;
        strongSelf.searchController.searchBar.showsCancelButton = YES;
    });

    self.searchController.searchResultsController.view.hidden = NO;
    return YES;
}

- (BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar{
    mainViewController *__weak weakSelf=self;
    dispatch_async(dispatch_get_main_queue(), ^{
        mainViewController *__strong strongSelf = weakSelf;
        strongSelf.searchController.searchBar.showsCancelButton = NO;
    });

    return YES;
}

- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar{
    mainViewController *__weak weakSelf=self;
    dispatch_async(dispatch_get_main_queue(), ^{
        mainViewController *__strong strongSelf = weakSelf;
        strongSelf.searchController.searchResultsController.view.hidden = YES;
    });

    [searchBar resignFirstResponder];
    }];
}
