打开搜索栏时导航栏隐藏

Question

我的Navigation Bar 中嵌入了一个UISearchController，当我单击它时，整个导航栏都会离开屏幕，直到我按下屏幕上的另一个区域然后它又回来了。这是视频的a link。 （视频可能已经上传了，所以给它一些时间，链接确实有效）

    self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
    self.searchController.dimsBackgroundDuringPresentation = NO;
    // Use the current view controller to update the search results.
    self.searchController.searchResultsUpdater = self;
    //Setting Style
    self.searchController.searchBar.barStyle = UIBarStyleBlack;
    self.searchController.searchBar.barTintColor = [UIColor colorWithRed:49.0/255.0 green:49.0/255.0 blue:61.0/255.0 alpha:1.0];
    self.searchController.searchBar.backgroundImage = [UIImage imageNamed:@"BG"];
    self.searchController.searchBar.placeholder = @"Search Artists, Songs, Albums etc.";
    self.searchController.searchBar.keyboardAppearance = UIKeyboardAppearanceDark;
    [self.searchController.searchBar sizeToFit];
    self.definesPresentationContext = YES;
    self.searchController.searchBar.tintColor = self.view.window.tintColor;
    [self.searchController.searchBar setTintColor:[UIColor colorWithRed:(226.0/255.0) green:(56.0/255.0) blue:(83.0/255.0) alpha:(1.0)]];
    self.searchController.searchBar.delegate = self;
    self.navigationItem.titleView = self.searchController.searchBar;
}

- (void)updateSearchResultsForSearchController:(UISearchController *)searchController{
    NSString *searchString = searchController.searchBar.text;
    NSLog(@"You searched for %@", searchString);
    [searchResultsTableView reloadData];
 }

-(void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar{
    [self.view addSubview:searchResultsTableView];
}

您需要添加以下内容

self.searchController.hidesNavigationBarDuringPresentation = NO;

停止 UISearchController 在激活时隐藏导航栏 (ref docs link)。
