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()
}

AppDelegate中:

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;
