Setting background of searchResultsTableView

I've a开发者_StackOverflow中文版 problem. I trying to set the background of an searchResultsTableView. Into my SearchViewController implementation, during the viewDidLoad, I want to set the background either of my self.tableView and of self.searchDisplayController.searchResultsTableView. I do this:

- (void)viewDidLoad {
    [super viewDidLoad];

    self.navigationItem.title = @"Search";

    UIColor *customColor = [UIColor colorWithRed:255.0 green:252.0 blue:227.0 alpha:1.0];
    self.tableView.backgroundColor = customColor;
    self.searchDisplayController.searchResultsTableView.backgroundColor = customColor;
}

After this, I've the tableView with my custom light-yellow color but, when I tap the search bar, and the tableView was replaced by searchDisplayController.searchResultsTableView, this results white.

Thanks for any help.

Use this method .. it will call when you start searching..

- (void)searchDisplayController:(UISearchDisplayController *)controller didLoadSearchResultsTableView:(UITableView *)tableView
{
    tableView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"default.png"]];
}

That i-Blue's solution with didLoadSearchResultsTableView works just fine. However I define search result background color this way:

- (void)viewWillAppear:(BOOL)animated
{
    self.searchDisplayController.
    searchResultsTableView.backgroundColor =
        [UIColor blueColor];
    [super viewWillAppear:animated];
}

So far no problems.

I had the same problem with UITableViewStyleGrouped-type background was white. This works for me (inspired by D-Griffin answer but added one line):

- (void)searchDisplayController:(UISearchDisplayController *)controller didLoadSearchResultsTableView:(UITableView *)tableView
{
    tableView.backgroundView = nil;
    tableView.backgroundColor = color;

}

I can't reply to Matteo in comments, so I'm doing it here. Besides, it might be useful for further reference.

If you want to add a color specifying the RGB code, there's one simple trick.

The documentation says the UIColor method initWithRed:green:blue:alpha accepts CGFLoat values, which are values between 0.0 and 1.0

so Instead of doing UIColor(Red:255.0, green:252.0, blue:227.0, alpha:1.0), which won't work, do the following :

let red:CGFLoat = 255/255
let green:CGFloat = 252/255
let blue:CGFloat = 227/255
UIColor(red:red, green:green, blue:blue,alpha:1.0)

this works perfectly well inside the searchDisplayController(UISearchDisplayController:controller, didLoadSearchResultsTableView UITableView:tableView)

this is swift, but you could translate this in obj C easily enough
