如何将自定义背景添加到uisearchdisplaycontroller的表视图?

您可以用与主表类似的方式设置背景图像,只在searchDisplayControllerDidbegInSearch委托方法中设置。例如:

- (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]; }

您也可以在实例化 UISearchDisplayController . 在我的应用程序中,我在 UITableView viewDidLoad 方法和正在匹配两个表之间的样式:

- (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;
}
