我正在使用 google Place Autocomplete API，我需要添加具有相同功能的 UITextField 而不是 UISearchBar。这是我从 https://developers.google.com/places/ios-api/autocomplete 获得的 UISearchBar 的工作代码.如果有人帮我从任何搜索关键字中获取地址数组，我会自己添加文本字段和表格 View 。就像从字符串(关键字)到数组(预测的位置)。

import UIKit
import GoogleMaps

class ViewController: UIViewController {

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

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
    self.definesPresentationContext = true
}
}

extension ViewController: GMSAutocompleteResultsViewControllerDelegate {
func resultsController(resultsController: GMSAutocompleteResultsViewController,
    didAutocompleteWithPlace place: GMSPlace) {
        searchController?.active = false
        print("Place name: ", place.name)
        print("Place address: ", place.formattedAddress!)
}

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

func didRequestAutocompletePredictionsForResultsController(resultsController: GMSAutocompleteResultsViewController) {
    UIApplication.sharedApplication().networkActivityIndicatorVisible = true
}

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

最佳答案

整合您的 GPA(Google Places API)。 POD 文件是:

pod 'GooglePlaces'
pod 'GooglePlacePicker'
pod 'GoogleMaps'

首先，将您的 KEY 提供给 AppDelegate.swift

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        GMSPlacesClient.provideAPIKey("Your KEY")
        return true
    }

首先，获取一个文本字段和一个 TableView 。然后将这些行添加到您的 ViewController.swift 文件并 Hook textField 和 tableView，最后运行它。

    import UIKit
    import GooglePlaces

    class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource{

    @IBOutlet weak var PlaceTextField: UITextField!

    @IBOutlet weak var tableView: UITableView!

    var tableData=[String]()

    var fetcher: GMSAutocompleteFetcher?

    override func viewDidLoad() {
        super.viewDidLoad()

        self.view.backgroundColor = UIColor.lightGray
        self.edgesForExtendedLayout = []

        // Set bounds to inner-west Sydney Australia.
        let neBoundsCorner = CLLocationCoordinate2D(latitude: -33.843366,
                                                    longitude: 151.134002)
        let swBoundsCorner = CLLocationCoordinate2D(latitude: -33.875725,
                                                    longitude: 151.200349)
        let bounds = GMSCoordinateBounds(coordinate: neBoundsCorner,
                                         coordinate: swBoundsCorner)

        // Set up the autocomplete filter.
        let filter = GMSAutocompleteFilter()
        filter.type = .establishment

        // Create the fetcher.
        fetcher = GMSAutocompleteFetcher(bounds: bounds, filter: filter)
        fetcher?.delegate = self as! GMSAutocompleteFetcherDelegate

        PlaceTextField.addTarget(self, action: #selector(ViewController.textFieldDidChanged(_:)), for: UIControlEvents.editingChanged)

        tableView.delegate = self
        tableView.dataSource = self

        tableView.reloadData()
    }

    // MARK: -UITextField Action

    @objc func textFieldDidChanged(_ textField:UITextField ){
        print(PlaceTextField.text!)
        fetcher?.sourceTextHasChanged(PlaceTextField.text!)
    }

    func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return 1
    }

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return tableData.count
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        var section = indexPath.section

        var row = indexPath.row

        let cell: UITableViewCell = UITableViewCell(style: UITableViewCellStyle.default, reuseIdentifier:"addCategoryCell")

        cell.selectionStyle =  UITableViewCellSelectionStyle.none
        cell.backgroundColor = UIColor.clear
        cell.contentView.backgroundColor = UIColor.clear
        cell.textLabel?.textAlignment = NSTextAlignment.left
        cell.textLabel?.textColor = UIColor.black
        cell.textLabel?.font = UIFont.systemFont(ofSize: 14.0)

        cell.textLabel?.text = tableData[indexPath.row]

        return cell
    }
}

extension ViewController: GMSAutocompleteFetcherDelegate {
    func didAutocomplete(with predictions: [GMSAutocompletePrediction]) {
        tableData.removeAll()

        for prediction in predictions {

            tableData.append(prediction.attributedPrimaryText.string)

            //print("\n",prediction.attributedFullText.string)
            //print("\n",prediction.attributedPrimaryText.string)
            //print("\n********")
        }

        tableView.reloadData()
    }

    func didFailAutocompleteWithError(_ error: Error) {
        print(error.localizedDescription)
    }
}

关于ios - 以相同的方式在 GMSAutocomplete 中使用文本字段而不是搜索栏，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35862490/
