How to add a custom background to UISearchDisplayController's table view? - iphone

Question

I want to add a custom UIImageView to UISearchDisplayController's table view background and set table view's background color to clearColor. Tried a few different approach but couldn't find the right solution. Any idea how to approach this?
Note: I don't want to add to searchDisplayController's searchResultsTableView's view hierarchy, but rather overlay another sibling view below it)

Answer 1

You can set the background image in a similar way you would for your main table, only set it in the searchDisplayControllerDidBeginSearch delegate method. For instance:-
- (void)searchDisplayControllerDidBeginSearch:(UISearchDisplayController *)controller {
[controller.searchResultsTableView setDelegate:self];
UIImageView *anImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"gradientBackground.png"]];
controller.searchResultsTableView.backgroundView = anImage;
[anImage release];
controller.searchResultsTableView.separatorStyle = UITableViewCellSeparatorStyleNone;
controller.searchResultsTableView.backgroundColor = [UIColor clearColor]; }

You can also do this wherever you instantiate your UISearchDisplayController. In my app I was doing this in my UITableView viewDidLoad method and was matching the styles between the two tables:
- (void)viewDidLoad
{
[super viewDidLoad];
self.tableView.separatorColor = [UIColor blackColor];
self.tableView.backgroundColor = [UIColor grayColor];
self.tableView.indicatorStyle = UIScrollViewIndicatorStyleWhite;
searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
searchController = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self];
searchController.delegate = self;
searchController.searchResultsDataSource = self;
searchController.searchResultsDelegate = self;
searchController.searchResultsTableView.separatorColor = self.tableView.separatorColor;
searchController.searchResultsTableView.backgroundColor = self.tableView.backgroundColor;
searchController.searchResultsTableView.indicatorStyle = UIScrollViewIndicatorStyleWhite;
}
