UISearchController被觸摸

Question

後找錯了，我加入編程UISearchController爲UIViewController，當UIViewController加載一切都很好，但是當我在UISearchController觸摸UISearchBar，將其移到底部，它正在尋找錯誤的。我第一次在代碼中添加UI元素。

override func viewDidLoad() { 
    super.viewDidLoad() 
    self.definesPresentationContext = true 
    searchController = ({ 
     let controllerSearch = UISearchController(searchResultsController: nil) 
     controllerSearch.searchBar.frame = CGRectMake(0, 20, self.view.frame.size.width, 44) 
     controllerSearch.delegate = self 
     controllerSearch.searchBar.delegate = self 
     controllerSearch.searchBar.searchBarStyle = UISearchBarStyle.Default 
     controllerSearch.dimsBackgroundDuringPresentation = false 
     controllerSearch.hidesNavigationBarDuringPresentation = false 
     controllerSearch.searchResultsUpdater = self 
     controllerSearch.searchBar.sizeToFit() 
     self.view.addSubview(controllerSearch.searchBar) 
     return controllerSearch 
    })() 
} 

雖然我做的是控制檯顯示的UISearchController框架，它顯示了正確的結果（0.0，20.0，320.0，44.0），請幫助我的人。 我仍然嘗試過，但結果是一樣的。

let frame = CGRectMake(0, 20, self.view.frame.size.width, 44) 
    controllerSearch.searchBar.frame = frame

我解決我的問題。我增加了以下元素

@IBOutlet weak var navigationItemSearch: UINavigationItem! 

而且改變了我的UISearchController

searchController = ({ 
     let controllerSearch = UISearchController(searchResultsController: nil) 
     controllerSearch.delegate = self 
     controllerSearch.searchBar.delegate = self 
     controllerSearch.searchBar.searchBarStyle = UISearchBarStyle.Prominent 
     controllerSearch.dimsBackgroundDuringPresentation = false 
     controllerSearch.hidesNavigationBarDuringPresentation = false // false 
     controllerSearch.searchBar.searchBarStyle = UISearchBarStyle.Default 
     controllerSearch.searchResultsUpdater = self 
     // placing 
     controllerSearch.searchBar.sizeToFit() 
     navigationItemSearch.titleView = controllerSearch.searchBar 
     // 
     controllerSearch.searchBar.spellCheckingType = UITextSpellCheckingType.Yes 
     controllerSearch.searchBar.autocapitalizationType = UITextAutocapitalizationType.None 
     controllerSearch.searchBar.keyboardType = UIKeyboardType.WebSearch 
     return controllerSearch 
    })()
