uisearchbar - 带有 UISearchController 的透明 UIStatusBar

Question

我正在使用以下代码来显示 UISearchBar

    searchController = UISearchController(searchResultsController: resultsTableViewController)
    searchController?.searchResultsUpdater = self
    searchController?.searchBar.sizeToFit()
    searchController?.searchBar.backgroundColor = UIColor.whiteColor()
    searchController?.searchBar.searchBarStyle = UISearchBarStyle.Minimal
    self.tableView?.tableHeaderView = searchController?.searchBar
    searchController?.delegate = self
    searchController?.dimsBackgroundDuringPresentation = false
    searchController?.searchBar.delegate = self

    definesPresentationContext = true

我的问题是，当我进入搜索模式时， View 变为全屏，我可以看到 tableview 的内容与 UISearchBar 重叠，这是一个错误吗？是否可以解决此问题？

看截图

我的解决方案

   func willPresentSearchController(searchController: UISearchController) {
    topBarView = UIView(frame: CGRectMake(0.0, 0.0, self.view.frame.size.width, 20.0))
    topBarView?.backgroundColor = UIColor.whiteColor()
    AppDelegate.sharedAppDelegate().window?.rootViewController?.view.addSubview(topBarView!)
}

func willDismissSearchController(searchController: UISearchController) {
    topBarView?.removeFromSuperview()
}

也许您可以在搜索过程中隐藏状态栏。自定义子类应该可以工作:

class MySearchController: UISearchController {
    override func prefersStatusBarHidden() -> Bool {
        return true
    }
}
