ios - 当导航栏半透明 = false 时 UISearchBar 超出屏幕边界

Question

我尝试将 UISearchBarController 添加到 tableView，但是当我设置 UINavigationBar.appearance().translucent = false 然后 UISearchBar 隐藏在屏幕之外

在 TableViewController 中

var resultSearchC: UISearchController = UISearchController()

override func viewDidLoad() {
    super.viewDidLoad()

    self.resultSearchC = ({
        let c = UISearchController(searchResultsController: nil)
        c.searchResultsUpdater = self

        c.searchBar.translucent = true

        c.searchBar.barTintColor =  .redColor()
        c.searchBar.sizeToFit()

        self.tableView.tableHeaderView = c.searchBar

        return c
    })()

    // self.edgesForExtendedLayout = .None

    self.tableView.reloadData()
}

应用委托(delegate):

let navBarAppearance = UINavigationBar.appearance()

    navBarAppearance.barStyle = .Black
    navBarAppearance.translucent = false

您需要在 viewDidLoad() 中将 extendedLayoutIncludesOpaqueBars 设置为 true。

extendedLayoutIncludesOpaqueBars = true;
