swift - 点击 Google 地方信息中的选择后显示 View Controller 的更好方法

Question

我正在按照教程在我的应用程序中使用 Google 地方信息，我注意到点击过滤结果后，Google 地方信息 View Controller 会被关闭，并显示调用 Google 地方信息的上一个屏幕。我不知道如何调整它，以便用户点击结果后它会直接转到另一个 Controller 。现在，我在点击结果后，Google Places Controller 被关闭，我调用 present 来调出另一个 Controller 。用户点击结果后，如何转到下一个 Controller 而不返回到调用 Google 地方信息的 Controller ？

import UIKit
import GooglePlaces

class TravelerViewController: UIViewController {

    @IBAction func autocompleteClicked(_ sender: UIButton) {
        let autocompleteController = GMSAutocompleteViewController()
        autocompleteController.delegate = self
        present(autocompleteController, animated: true, completion: nil)
    }

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


    /*
    // MARK: - Navigation

    // In a storyboard-based application, you will often want to do a little preparation before navigation
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        // Get the new view controller using segue.destinationViewController.
        // Pass the selected object to the new view controller.
    }
    */
}

extension TravelerViewController: GMSAutocompleteViewControllerDelegate {

    // Handle the user's selection.
    func viewController(_ viewController: GMSAutocompleteViewController, didAutocompleteWith place: GMSPlace) {
        print("Place name: \(place.name)")
        print("Place address: \(place.formattedAddress)")
        print("Place attributions: \(place.attributions)")
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let controller = storyboard.instantiateViewController(withIdentifier: "TravelerResults")

        dismiss(animated: true, completion: nil)
        self.present(controller, animated: true, completion: nil)
    }

    func viewController(_ viewController: GMSAutocompleteViewController, didFailAutocompleteWithError error: Error) {
        // TODO: handle the error.
        print("Error: ", error.localizedDescription)
    }

    // User canceled the operation.
    func wasCancelled(_ viewController: GMSAutocompleteViewController) {
        dismiss(animated: true, completion: nil)
    }

    // Turn the network activity indicator on and off again.
    func didRequestAutocompletePredictions(_ viewController: GMSAutocompleteViewController) {
        UIApplication.shared.isNetworkActivityIndicatorVisible = true
    }

    func didUpdateAutocompletePredictions(_ viewController: GMSAutocompleteViewController) {
        UIApplication.shared.isNetworkActivityIndicatorVisible = false
    }

}

为打开的 View Controller 创建单独的函数。

@objc func openVC() {
    let controller = self.storyboard?.instantiateViewController(withIdentifier: "TravelerResults")
    self.present(controller!, animated: true, completion: nil)
}

在自动完成中调用此函数。

func viewController(_ viewController: GMSAutocompleteViewController, didAutocompleteWith place: GMSPlace) {
        print("Place name: \(place.name)")
        print("Place address: \(place.formattedAddress)")
        print("Place attributions: \(place.attributions)")
        dismiss(animated: true, completion: nil)
        openVC()

    }
