当导航栏半透明= false时，UISearchBar超出屏幕范围

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

TableViewController中的

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()
}

的AppDelegate：

let navBarAppearance = UINavigationBar.appearance()

    navBarAppearance.barStyle = .Black
    navBarAppearance.translucent = false

Answer 1

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

extendedLayoutIncludesOpaqueBars = true;
