GooglePlacesAutocomplete在活动时向上移动搜索栏

Question

目前，我遵循了这些步骤，用Google Place实现了一个自动完成搜索栏。

control

到目前为止，它还不错，但是当我点击搜索栏时，它会向下移动，这就是我不想要的。

我的当前代码与本教程中的代码完全相同(我也在它之后尝试了错误修复，不起作用)

var resultsViewController: GMSAutocompleteResultsViewController?
    var searchController: UISearchController?
    var resultView: UITextView?

    override func viewDidLoad() {
        super.viewDidLoad()
        self.title = "Event-Filter";

        resultsViewController = GMSAutocompleteResultsViewController()
        resultsViewController?.delegate = self

        searchController = UISearchController(searchResultsController: resultsViewController)
        searchController?.searchResultsUpdater = resultsViewController

        let subView = UIView(frame: CGRect(x: 0, y: 0.0, width: self.view.frame.width, height: 45.0))

        subView.addSubview((searchController?.searchBar)!)
        view.addSubview(subView)
        searchController?.searchBar.sizeToFit()
        searchController?.searchBar.placeholder = "Enter a specific place!";

        navigationController?.navigationBar.isTranslucent = false
        searchController?.hidesNavigationBarDuringPresentation = false

        // When UISearchController presents the results view, present it in
        // this view controller, not one further up the chain.
        definesPresentationContext = true
    }

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

    //Handle User Selection

    func resultsController(_ resultsController: GMSAutocompleteResultsViewController, didAutocompleteWith place: GMSPlace) {
        searchController?.isActive = false
        searchController?.searchBar.text = place.formattedAddress;
        print("Place name: \(place.name)")
        print("Place address: \(place.formattedAddress ?? "not found")")
        print("Place lat:" + String(place.coordinate.latitude))

    }

    func resultsController(_ resultsController: GMSAutocompleteResultsViewController,
                           didFailAutocompleteWithError error: Error){
        let backend = BackendService()
        backend.alert(view: self, message: error.localizedDescription, title: "Something went wrong!")
    }

    // Turn the network activity indicator on and off again.
    func didRequestAutocompletePredictions(forResultsController resultsController: GMSAutocompleteResultsViewController) {
        UIApplication.shared.isNetworkActivityIndicatorVisible = true
    }

    func didUpdateAutocompletePredictions(forResultsController resultsController: GMSAutocompleteResultsViewController) {
        UIApplication.shared.isNetworkActivityIndicatorVisible = false
    }

嗯，我也遇到了同样的问题，我通过使用下面的代码行使它正确地工作：

definesPresentationContext = false

我对它进行了大量的测试，它对我来说非常有效。
