Question

您好，我使用

设置了搜索控制器

private func setupSearchbar() {
        searchController = UISearchController(searchResultsController: nil)
        searchController.searchResultsUpdater = self
        searchController.obscuresBackgroundDuringPresentation = false
        searchController.searchBar.placeholder = "Search Contacts"

        self.navigationItem.searchController = searchController
        self.definesPresentationContext = true

    }

一切正常，直到我添加这段代码

    UINavigationBar.appearance().isOpaque = true
    UINavigationBar.appearance().isTranslucent = false
    UINavigationBar.appearance().barTintColor = UIColor(named: "PrimaryDark")
    UINavigationBar.appearance().tintColor = UIColor.white
    UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.font:Constants.AppTheme.Fonts.font(type: .FONT_BOLD, size: 22) ,NSAttributedString.Key.foregroundColor:UIColor.white]

    UINavigationBar.appearance().largeTitleTextAttributes   = [NSAttributedString.Key.font:Constants.AppTheme.Fonts.font(type: .FONT_BOLD, size: 34) ,NSAttributedString.Key.foregroundColor:UIColor.white]

现在，当我点击搜索栏时，会出现大的底部黑条

该如何解决？

好的，我可以解决此问题。我正在分享此信息，因此这可能对其他面临相同问题的人有所帮助。

解决此问题。在视图中将出现我将self.extendedLayoutIncludesOpaqueBars设置为true的方法

 override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        self.extendedLayoutIncludesOpaqueBars = true

    }

希望对某人有帮助：）
