Question

我正在开发一款应用，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。我附上了代码

    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searchBar时，应用程序会在输入任何字符时崩溃。我没有看到任何结果，甚至不能输入单个单词。我得到的错误是

该项目使用Swift 2.3在Xcode 8上。

我不知道为什么我收到此错误而无法解决此错误。请仔细研究一下。任何帮助将不胜感激。

Answer 1

替换以下内容：

旧：

#import <GoogleMaps/GooglePlaces.h>
[GMSServices provideAPIKey:GoogleAPIKey]

更新了工作代码：

@import GooglePlaces;
[GMSPlacesClient provideAPIKey:GoogleAPIKey];

最新的SDK指向GooglePlaces / GooglePlaces.h，而不是GoogleMaps / GooglePlaces.h 检查此链接： https://developers.google.com/places/migrate-to-v2

Answer 2

objc_exception_throw, queue = 'com.apple.main-thread', stop reason = breakpoint 1.2

有些异常断点似乎是由GoogleMaps或GooglePlaces SDK的部分内容触发的，当您点击搜索栏时就会显而易见。

禁用所有异常的异常断点。
