当UISearchController处于活动状态时，iOS 9 searchBar从表标题视图中消失 [英] iOS 9 searchBar disappears from table header view when UISearchController is active

问题描述

结构:

View1(单击一个按钮)->模态显示(MyModalView:UITableViewController)

View1 (click a button) -> present modally (MyModalView: UITableViewController)

MyModalView嵌入了UISearchController. UISearchController的searchBar放在MyModalView.tableView.tableHeaderView中.

MyModalView has UISearchController embedded. The searchBar of UISearchController is placed in MyModalView.tableView.tableHeaderView.

自iOS 8.0起，它一直运行良好.但是在iOS 9上，当UISearchController处于活动状态时，searchBar消失.请在下面看这些图片

It's been working fine since iOS 8.0. However on iOS 9, the searchBar disappear when the UISearchController is active. Please take a look at theses pictures below

模式视图:

在iOS 8上处于活动状态的UISearchController:

UISearchController active on iOS 8:

在iOS 9上有效的UISearchController:

UISearchController active on iOS 9:

非常标准的代码:

override func viewDidLoad() {
    super.viewDidLoad()

    // Dynamically create a search controller using anonymous function
    self.resultSearchController = ({
        let controller = UISearchController(searchResultsController: nil)
        controller.searchResultsUpdater = self
        controller.dimsBackgroundDuringPresentation = false

        controller.searchBar.sizeToFit()
        controller.searchBar.delegate = self

        self.tableView.tableHeaderView = controller.searchBar

        return controller
    })()

    // Auto sizing row & cell height
    self.tableView.estimatedRowHeight = 130
    self.tableView.rowHeight = UITableViewAutomaticDimension
    self.definesPresentationContext = true

    // No footer for better presentation
    self.tableView.tableFooterView = UIView.init(frame: CGRectZero)
}

此问题也发生在iOS 9.1 beta中...

I got a solution that solved my problem. It is setting Extend Edges - Under Opaque Bars of my (MyModalView: UITableViewController) to true in the Storyboard using Interface Builder.

MyModalView:UITableViewController，在使用Interface Builder的情节提要中具有

延伸边缘: -在顶部栏下打勾 -在底部栏下打勾 -在不透明条下面打勾

Extend Edges: - Under Top Bars ticked - Under Bottom Bars ticked - Under Opaque Bars ticked
