SearchController SearchBar宽度问题iOS11

Question

I am trying to add SearchController SearchBar programmatically in one of UIVIew as subView but initially it working properly up to iOS 10 but getting issue in iOS11 width getting increased get displaced.

I tried all possible solutions, Created Custom class init SearchBar frame with CGRect.zero & even hide cancel button. Still i does not understanding where I am doing wrong.

Initial Screen:

Issue is here when i clicked on SearchBar

Irony is its not working even i am trying to reset frame width to 100.0f by calling method viewWillLayoutSubviews from searchBarShouldBeginEditing

func setUpSearchBar(){
        self.automaticallyAdjustsScrollViewInsets = false

        resultsViewController = GMSAutocompleteResultsViewController()
        resultsViewController?.delegate = self as GMSAutocompleteResultsViewControllerDelegate
        searchController = CustomSearchController(searchResultsController: resultsViewController)
        searchController?.searchResultsUpdater = resultsViewController

        //resultsViewController?.view.frame = searchAndButtonView.bounds
        //let subView = UIView(frame: CGRect(x: 0, y: 65.0, width: 350.0, height: 45.0))


         searchController?.searchBar.frame = CGRect(x: 0, y: 0, width: searchView.frame.size.width, height: searchView.frame.size.height)

        searchController?.searchBar.delegate = self
        searchView.addSubview((searchController?.searchBar)!)

        searchView.translatesAutoresizingMaskIntoConstraints = false
        searchController?.searchBar.sizeToFit()
        searchController?.hidesNavigationBarDuringPresentation = false

        searchController?.searchBar.searchBarStyle = .minimal
        definesPresentationContext = false

        self.extendedLayoutIncludesOpaqueBars = true
        self.edgesForExtendedLayout = .top

    }

CustomSearchController.swift

class CustomSearchController: UISearchController,UISearchBarDelegate{

    let noCancelButtonSearchBar = NoCancelButtonSearchBar()

    lazy var _searchBar: NoCancelButtonSearchBar = {
        [unowned self] in
        let customSearchBar = NoCancelButtonSearchBar(frame: CGRect.zero)
        return customSearchBar
        }()

    override var searchBar: UISearchBar {
        get {
            return _searchBar
        }
    }

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


    /*
    // MARK: - Navigation

    // In a storyboard-based application, you will often want to do a little preparation before navigation
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        // Get the new view controller using segue.destinationViewController.
        // Pass the selected object to the new view controller.
    }
    */

}

class NoCancelButtonSearchBar: UISearchBar {
    override func setShowsCancelButton(_ showsCancelButton: Bool, animated: Bool) { /*
    void */ }

}

After lot of attempts i resolved issue by following way,

I removed customised CustomSearchController class & used simple UISearchController .

func setUpSearchBar(){
        self.automaticallyAdjustsScrollViewInsets = false

        resultsViewController = GMSAutocompleteResultsViewController()
        resultsViewController?.delegate = self as GMSAutocompleteResultsViewControllerDelegate
        searchController = UISearchController(searchResultsController: resultsViewController)
        searchController?.searchResultsUpdater = resultsViewController


         searchController?.searchBar.frame = CGRect(x: 0, y: 0, width: searchView.frame.size.width, height: searchView.frame.size.height)

        let searchBarContainer = SearchBarContainerView(customSearchBar: searchController?.searchBar)  
        searchBarContainer.frame = CGRect(x: 0, y: 0, width: view.frame.width, height: 44)
        searchController?.searchBar.delegate = self
        searchView.addSubview(searchBarContainer)

        searchView.translatesAutoresizingMaskIntoConstraints = false
        searchController?.searchBar.sizeToFit()
        searchController?.hidesNavigationBarDuringPresentation = false

        searchController?.searchBar.searchBarStyle = .minimal
        definesPresentationContext = false

        self.extendedLayoutIncludesOpaqueBars = true
        self.edgesForExtendedLayout = .top

    }

And add SearchBarContainerView class,

class SearchBarContainerView: UIView {  

    let searchBar: UISearchBar  

    init(customSearchBar: UISearchBar) {  
        searchBar = customSearchBar  
        super.init(frame: CGRect.zero)  

        addSubview(searchBar)  
    }

    override convenience init(frame: CGRect) {  
        self.init(customSearchBar: UISearchBar())  
        self.frame = frame  
    }  

    required init?(coder aDecoder: NSCoder) {  
        fatalError("init(coder:) has not been implemented")  
    }  

    override func layoutSubviews() {  
        super.layoutSubviews()  
        searchBar.frame = bounds  
    }  
}

Following is working screenshot:

Try this code. it worked for me. I was also facing the same issue.

override func viewWillLayoutSubviews() {
        super.viewWillLayoutSubviews()
        searchbar.invalidateIntrinsicContentSize()
    }
