我正在开发一个应用程序，并将GoogleMaps和GooglePlaces SDK集成到其中。当我在基于iOS 10的设备上打开它时，单击搜索栏会使应用程序崩溃。我还添加了GMSAutocompleteResultsViewController。我在附上密码
var mapView: GMSMapView?
var resultsViewController: GMSAutocompleteResultsViewController?
var searchController: UISearchController?
override func viewDidLoad() {
super.viewDidLoad()
mapView = GMSMapView()
mapView.frame = CGRectMake(0, 0, width, height)
mapView.mapType = kGMSTypeNormal
self.view.addSubview(mapView)
mapView.delegate = self
resultsViewController = GMSAutocompleteResultsViewController()
resultsViewController?.delegate = self
searchController = UISearchController(searchResultsController: resultsViewController)
searchController?.searchResultsUpdater = resultsViewController
searchController!.view.frame = CGRectMake(0, 0, width, height)
let subView = UIView(frame: CGRectMake(0, 0, width, 45.0))
subView.addSubview((searchController?.searchBar)!)
self.view.addSubview(subView)
searchController?.hidesNavigationBarDuringPresentation = false
searchController?.modalPresentationStyle = UIModalPresentationStyle.Popover
self.definesPresentationContext = true
searchController?.searchBar.delegate = self
}
extension ViewController: GMSAutocompleteResultsViewControllerDelegate {
func resultsController(resultsController: GMSAutocompleteResultsViewController, didAutocompleteWithPlace place: GMSPlace) {
searchController?.active = false
mapView.animateToLocation(place.coordinate)
}
func resultsController(resultsController: GMSAutocompleteResultsViewController, didFailAutocompleteWithError error: NSError){
print("Error: ", error.description)
}
func didRequestAutocompletePredictions(viewController: GMSAutocompleteViewController) {
UIApplication.sharedApplication().networkActivityIndicatorVisible = true
}
func didUpdateAutocompletePredictions(viewController: GMSAutocompleteViewController) {
UIApplication.sharedApplication().networkActivityIndicatorVisible = false
}
}
extension ViewController: UISearchBarDelegate {
func searchBarSearchButtonClicked(searchBar: UISearchBar) {
searchBar.resignFirstResponder()
}
func searchBarCancelButtonClicked(searchBar: UISearchBar) {
searchBar.resignFirstResponder()
searchController?.active = false
}
func searchBarTextDidBeginEditing(searchBar: UISearchBar) {
let doneBtn = self.navigationItem.rightBarButtonItem
doneBtn?.enabled = false
}
func searchBarTextDidEndEditing(searchBar: UISearchBar) {
let doneBtn = self.navigationItem.rightBarButtonItem
doneBtn?.enabled = true
}
}
每当我点击搜索栏时，应用程序在键入任何字符时都会崩溃。我没有看到任何结果，甚至连一个字都不会打。我得到的错误是

这个项目是在Xcode8和Swift 2.3上进行的。
我不知道为什么我会犯这个错误而无法解决。请调查一下。任何帮助都将不胜感激。
最佳答案
替换以下内容：
旧的：
#import <GoogleMaps/GooglePlaces.h>
[GMSServices provideAPIKey:GoogleAPIKey]
更新的工作代码：
@import GooglePlaces;
[GMSPlacesClient provideAPIKey:GoogleAPIKey];
最新的SDK指向GooglePlaces/GooglePlaces.h，而不是GoogleMaps/GooglePlaces.h
