How do I cover the "no results" text in UISearchDisplayController's searchResultTableView?

Question

I don't want to show the "no results" text while my server is processing a search query.

I figured out the exact coordinates of the table cell that contains the label and attempted to cover it.

self.noResultsCoverView = [[[UIView alloc] initWithFrame:CGRectMake(
    0.0, 
    44.0, 
    320.0, 
    43.0
)] autorelease];
self.noResultsCoverView.backgroundColor = [UIColor whiteColor];
[self.searchDisplayController.searchResultsTableView addSubview:self.noResultsCoverView];

To my chagrin, my cover was above the table view, but below the label. I need the cover to be above the label. searchResultsTableView::bringSubviewToFront didn't work, which makes me believe that the label isn't a child of the searchResultsTableView at all.

BTW, this Stack Overflow answer doesn't quite work for me. It works on the very first search, but flashes a weird black cover on subsequent searches.

The easiest way to work around this is to return 1 in numberOfRowsInSection while the query is in progress and leave the dummy cell empty or set its hidden property to YES so it is not visible.
