我最近將我的應用程序升級到了swift 3，並且每當它試圖在谷歌地圖中調用自動完成視圖控制器時，它都會崩潰。我知道一個API密鑰不是問題，因爲它在我升級到swift 3和xcode 8之前使用它時正常工作。我也知道這是因爲該應用程序仍然能夠顯示谷歌地圖。 這裏是我的代碼：GMSAutoCompleteViewController崩潰 - Swift 3
extension AdditionalSetupViewController: GMSAutocompleteViewControllerDelegate {
func viewController(_ viewController: GMSAutocompleteViewController, didAutocompleteWith place: GMSPlace) {
let locationCoordinate = place.coordinate
if homeClicked {
homeAddress = [locationCoordinate.latitude, locationCoordinate.longitude]
}
else if homeAddress == [] {
}
else {
let coordString = "\(locationCoordinate.latitude) \(locationCoordinate.longitude)".replacingOccurrences(of: ".", with: ",")
// let coordString = "\(locationCoordinate.latitude) \(locationCoordinate.longitude)".stringByReplacingOccurrencesOfString(".", withString: ",")
ref = FIRDatabase.database().reference()
let currentUser: String = (FIRAuth.auth()?.currentUser?.uid)!
let address = ref.child("schoolOrWorkAddress").child(coordString)
let childUpdates = [currentUser: homeAddress]
address.updateChildValues(childUpdates)
finishButton.alpha = 1
finishButton.isEnabled = true
}
let schoolorWorkCoords = "\(locationCoordinate.latitude) \(locationCoordinate.longitude)".replacingOccurrences(of: ".", with: ",")
// let schoolorWorkCoords = "\(locationCoordinate.latitude) \(locationCoordinate.longitude)".stringByReplacingOccurrencesOfString(".", withString: ",")
let userID = (FIRAuth.auth()?.currentUser?.uid)!
_ = ref.child("posts").child(userID).key
let additionalBasicInfo = ["schoolOrWorkAddress": schoolorWorkCoords, "homeAddress": homeAddress] as [String : Any]
let usersRef = ref.child("users/\(userID)")
usersRef.updateChildValues(additionalBasicInfo as [NSObject : AnyObject])
self.dismiss(animated: true, completion: nil)
}
func viewController(_ viewController: GMSAutocompleteViewController, didFailAutocompleteWithError error: Error) {
print(error)
}
func wasCancelled(_ viewController: GMSAutocompleteViewController) {
self.dismiss(animated: true, completion: nil)
}
func didRequestAutocompletePredictions(_ viewController: GMSAutocompleteViewController) {
UIApplication.shared.isNetworkActivityIndicatorVisible = true
}
func didUpdateAutocompletePredictions(_ viewController: GMSAutocompleteViewController) {
UIApplication.shared.isNetworkActivityIndicatorVisible = false
}
}
以下是錯誤輸出：

我不就好像這能幫助，但這裏是我的視圖控制器的其餘部分的代碼，以及：
class AdditionalSetupViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
override func viewDidLoad() {
finishButton.alpha = 0.4
finishButton.isEnabled = false
navigationController?.navigationBar.barTintColor = UIColor(red: 46, green: 204, blue: 113, alpha: 0)
}
@IBOutlet weak var mapView : GMSMapView!
var homeClicked = false
var homeAddress: [Double] = []
@IBAction func addYourHomeAddress(sender: AnyObject) {
homeClicked = true
createGMSViewController()
}
@IBAction func addYourSchoolOrWorkAddress(sender: AnyObject) {
homeClicked = false
createGMSViewController()
}
func createGMSViewController() {
let searchAutoCompleteController = GMSAutocompleteViewController()
searchAutoCompleteController.delegate = self
self.present(searchAutoCompleteController, animated: true, completion: nil)
}
@IBOutlet weak var finishButton: UIButton!
@IBAction func finishButton(sender: AnyObject) {
let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
let nextViewController = storyBoard.instantiateViewController(withIdentifier: "TableView") as! UITabBarController
self.present(nextViewController, animated:true, completion:nil)
}
}
我不知道爲什麼它崩潰時，它會打電話給我，但任何幫助將不勝感激！
