Question

在我的应用程序中，我想使用多个（两个）搜索控制器进行GooglePlace自动完成我已经实现了一个搜索控制器它工作正常但现在我不知道如何在同一视图控制器中实现另一个搜索控制器请提供一些知识实现它。

这里我给出了我实现单一搜索控制器的代码。

var resultsViewController: GMSAutocompleteResultsViewController?
var pickUpSearchController: UISearchController?
var dropSearchController: UISearchController?

let pickUpSearchBarBackView = UIView()
let dropSearchBarBackView = UIView()


override func viewDidLoad() {
    super.viewDidLoad()

    pickUpSearchBarFunction()

}
override func viewDidLayoutSubviews() {
    var pickUpSearchBarFrame = pickUpSearchController?.searchBar.frame
    pickUpSearchBarFrame?.size.width = (pickUpSearchController?.searchBar.frame.size.width)!
    pickUpSearchController?.searchBar.frame = pickUpSearchBarFrame!
}
func pickUpSearchBarFunction() {
    resultsViewController = GMSAutocompleteResultsViewController()
    resultsViewController?.delegate = self
    pickUpSearchController = UISearchController(searchResultsController: resultsViewController)
    pickUpSearchController?.searchResultsUpdater = resultsViewController

    if UIScreen.main.bounds.size.width == 320 {
        pickUpSearchBarBackView.frame = CGRect(x: 10, y: 75.0, width: 300.0, height: 50.0)
    }
    else if(UIScreen.main.bounds.size.width == 375)
    {
        pickUpSearchBarBackView.frame = CGRect(x: 10, y: 75.0, width: 355.0, height: 60.0)
    }
    else if(UIScreen.main.bounds.size.width == 414)
    {
        pickUpSearchBarBackView.frame = CGRect(x: 10, y: 75.0, width: 394.0, height: 60.0)
    }

    pickUpSearchBarBackView.addSubview((pickUpSearchController?.searchBar)!)
    //(pickUpSearchController?.searchBar)!.center = self.pickUpSearchBarBackView.center
    view.addSubview(pickUpSearchBarBackView)
    pickUpSearchController?.searchBar.sizeToFit()
    pickUpSearchController?.searchBar.barTintColor = UIColor.white
    pickUpSearchController?.hidesNavigationBarDuringPresentation = false
    definesPresentationContext = true

    navigationController?.navigationBar.isTranslucent = false
    pickUpSearchController?.hidesNavigationBarDuringPresentation = false
    self.extendedLayoutIncludesOpaqueBars = true
    self.edgesForExtendedLayout = .top
}


extension HomeViewController: GMSAutocompleteResultsViewControllerDelegate {
func resultsController(_ resultsController: GMSAutocompleteResultsViewController,
                       didAutocompleteWith place: GMSPlace) {

    pickUpSearchController?.isActive = false
    //strForLat = "\(place.coordinate.latitude)"
    //strForLong = "\(place.coordinate.longitude)"

    let coordinateSearch: CLLocationCoordinate2D? = place.coordinate
    print(coordinateSearch!.latitude)
    print(coordinateSearch!.longitude)
    strForLat = "\(coordinateSearch!.latitude)"
    strForLong = "\(coordinateSearch!.longitude)"

    globalCamera = GMSCameraPosition.camera(withLatitude: Double(strForLat)!, longitude: Double(strForLong)!, zoom: zoomLevel)
    self.googleMapsView.camera = globalCamera
    //let marker = GMSMarker()
    customerMarker.position = CLLocationCoordinate2DMake(Double(strForLat)!, Double(strForLong)!)
    customerMarker.title = place.name
    customerMarker.snippet = place.formattedAddress
    customerMarker.map = self.googleMapsView
    //globalMarker.icon = GMSMarker.markerImage(with: UIColor.blue)
    customerMarker.tracksViewChanges = true
    self.dismiss(animated: true, completion: nil) // dismiss after select place
    pickUpSearchController?.searchBar.text = place.formattedAddress

    print("Place name: \(place.name)")
    print("Place address: \(place.formattedAddress!)")
    print("Place attributions: \(place.attributions)")

    //getLatLngForaddress(addressStr: (searchController?.searchBar.text)!)
    getLatandLngForPickUpaddress()
}

func resultsController(_ resultsController: GMSAutocompleteResultsViewController,
                       didFailAutocompleteWithError error: Error){
    print("Error: ", error.localizedDescription)
}

// 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
}
func wasCancelled(_ viewController: GMSAutocompleteViewController) {
    self.dismiss(animated: true, completion: nil) // when cancel search
}

}

您可以通过将resultsController与特定于UISearchController的searchResultsController进行比较来处理它。

extension ViewController: GMSAutocompleteResultsViewControllerDelegate {
func resultsController(_ resultsController: GMSAutocompleteResultsViewController,
                       didAutocompleteWith place: GMSPlace) {

    if resultsController == sourceResultsViewController {

        // Do something with the selected place.

    } else if resultsController == destinationResultsViewController {

        // Do something with the selected place.

    }

如何在同一视图控制器中使用多个搜索控制器？
