无法将视图推送到searchResultsController

Question

我有一个TableViewController,一个SearchResultsController和一个WebViewController.当我单击TableViewController中的一个单元格时,它会推动WebViewController打开一个与单元格相关的URL.

TableViewController有一个UISearchController,它将结果过滤到SearchResultsController中,但是当在SearchResultsController中单击一个单元格时,WebViewController不会被推送.

以下是SearchResultsController的didSelectRowAtIndexPath的代码:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    WebViewController *webViewController = [[WebViewController alloc] init];

    NSString *extensionURL = (self.searchResults[indexPath.row])[@"url"];
    NSURL *baseURL = [NSURL URLWithString:@"http://www.baseurl.com"];
    NSURL *URL = [NSURL URLWithString:extensionURL relativeToURL:baseURL];

    webViewController.title = (self.searchResults[indexPath.row])[@"title"];
    NSLog(@"%@", URL);
    webViewController.URL = URL;
    [self.navigationController pushViewController:webViewController
                                         animated:YES];

}

我包含了NSLog,看看当单击一个单元格时是否发生了什么,它确实在控制台中显示了url.这让我觉得问题出在navigationController上.

在线查看似乎应该将UISearchController包装在UISearchContainerViewController中,然后将其放入navigationController中.我还是应用程序开发的新手,无法弄清楚如何或在何处执行此操作.

我在我的TableViewController的viewDidLoad中调用我的SearchResultsController,如下所示:

- (void)viewDidLoad
{
    [super viewDidLoad];

    SearchResultsViewController *controller = [[SearchResultsViewController alloc] initWithStyle:UITableViewStylePlain];
    [self addObserver:controller forKeyPath:@"results" options:NSKeyValueObservingOptionNew context:nil];

    self.searchController = [[UISearchController alloc] initWithSearchResultsController: controller];
    self.searchController.searchResultsUpdater = self;
    self.searchController.hidesNavigationBarDuringPresentation = NO;
    self.searchController.dimsBackgroundDuringPresentation = NO;
    self.searchController.delegate = self;
    self.definesPresentationContext = YES; 

    UISearchBar *searchBar = [[UISearchBar alloc] init];
    searchBar = self.searchController.searchBar;
    searchBar.searchBarStyle = UISearchBarStyleMinimal;
    UITextField *searchField = [searchBar valueForKey:@"_searchField"];
    searchBar.barTintColor = [UIColor whiteColor];
    searchBar.tintColor = [UIColor whiteColor];

    self.navigationItem.titleView = searchBar;

}

这是我应该嵌入我的SearchResultsController的地方吗？

在进行搜索时,您将呈现NewModalViewController,因此您需要做的就是在呈现搜索控制器时推送viewcontroller的一些步骤

1)self.definesPresentationContext = YES;

在此之后你应该推动你的viewcontroller

2)[self.presentingViewController.navigationController pushViewController:sec animated:YES];

注意:目前的modalviewcontroller没有导航控制器,所以正常的推送编码不会工作,因为它没有分配给导航.
