解决方案

It's not directly accessible, so you'll have to do it the old fashioned way and manually sift through the subviews of your searchDisplayController.searchResultsTableView. Here's one example:

UITableView *tableView = self.searchDisplayController.searchResultsTableView;
for( UIView *subview in tableView.subviews ) {
     if( [subview class] == [UILabel class] ) {
         UILabel *lbl = (UILabel*)subview; // sv changed to subview.
         lbl.text = @"My custom string";
     }
}

I wouldn't recommend this since you're relying on internal behavior of the searchResultsTableView which is more than likely going to change at some point, breaking your app. Opening a bug/feature request with Apple would be a good way to go here.
