据我所知，您的 View Controller 没有设置 definesPresentationContext 属性。如果你不设置这个，奇怪的事情一定会发生。尝试像这样更新您的代码:

let resultController = mainStoryboard.instantiateViewControllerWithIdentifier("SearchTableViewController") as! UITableViewController

self.searchController = UISearchController(searchResultsController: resultController)
//self.searchController.searchResultsUpdater = self
//self.searchController.delegate = self
//self.searchController.searchBar.delegate = self
self.searchController.searchBar.tintColor = UIColor.whiteColor()
self.searchController.searchBar.placeholder = "Search Outlets"
self.searchController.dimsBackgroundDuringPresentation = false
self.searchController.hidesNavigationBarDuringPresentation = false

self.definesPresentationContext = true

最后一行是我添加的行。当我在我自己的应用程序中对此进行测试时，未指定此行会导致您看到的行为。
