Question

我正在使用搜索栏来使用Google地方自动填充功能。但是，当我将搜索栏放在GMSMapView之上时，它无法正常工作。当我注释掉loadView（）函数时，它完全正常。有没有办法在Google地图中使用地方自动填充功能？

import UIKit
import GoogleMaps

class ViewController: UIViewController {

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

  override func loadView() {
    let camera = GMSCameraPosition.cameraWithLatitude(1.285, longitude: 103.848, zoom: 12)
    let mapView = GMSMapView.mapWithFrame(.zero, camera: camera)
    self.view = mapView
  }

  override func viewDidLoad() {
    super.viewDidLoad()

    resultsViewController = GMSAutocompleteResultsViewController()
    resultsViewController?.delegate = self

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

    let subView = UIView(frame: CGRectMake(0, 65.0, 350.0, 45.0))

    subView.addSubview((searchController?.searchBar)!)
    self.view.addSubview(subView)
    searchController?.searchBar.sizeToFit()
    searchController?.hidesNavigationBarDuringPresentation = false

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

// Handle the user's selection.
extension ViewController: GMSAutocompleteResultsViewControllerDelegate {
  func resultsController(resultsController: GMSAutocompleteResultsViewController,
    didAutocompleteWithPlace place: GMSPlace) {
      searchController?.active = false
      // Do something with the selected place.
      print("Place name: ", place.name)
      print("Place address: ", place.formattedAddress)
      print("Place attributions: ", place.attributions)
  }

  func resultsController(resultsController: GMSAutocompleteResultsViewController,
    didFailAutocompleteWithError error: NSError){
      // TODO: handle the error.
      print("Error: ", error.description)
  }

  // Turn the network activity indicator on and off again.
  func didRequestAutocompletePredictionsForResultsController(resultsController: GMSAutocompleteResultsViewController) {
    UIApplication.sharedApplication().networkActivityIndicatorVisible = true
  }

  func didUpdateAutocompletePredictionsForResultsController(resultsController: GMSAutocompleteResultsViewController) {
    UIApplication.sharedApplication().networkActivityIndicatorVisible = false
  }
}

上面的代码来自https://developers.google.com/maps/documentation/ios-sdk/map和https://developers.google.com/places/ios-api/autocomplete。我复制了这些用于测试，但仍然无法正常工作。

抱歉，我还没有写评论的声誉，但我认为这可以帮助您找出问题。

首先调用super.loadView（），初始化GMSMapView时，必须设置帧大小。最后将mapView添加到子视图中。

    override func loadView() {

    super.loadView()

    let camera = GMSCameraPosition.cameraWithLatitude(1.285, longitude: 103.848, zoom: 12)
    let mapView = GMSMapView.mapWithFrame(self.view.frame, camera: camera)
    self.view.addSubview(mapView)
   }

Swift Google Place自动填充功能无法与Google地图配合使用
