Ios 在GMSAutocomplete中使用文本字段而不是搜索栏，方法相同

我正在使用google Place Autocomplete API，我需要添加UITextField，而不是具有相同功能的UISearchBar。这是我从UISearchBar获得的工作代码。如果有人帮我从任何搜索关键字中获取地址数组，我将自己添加textfield和tableview。比如从字符串（关键字）到数组（预测位置）

如果您使用UITextField和自己的UITableView来代替UISearchController，那么直接使用该类就更容易了

GoogleMaps Cocoapod的一个代码示例展示了如何做到这一点。如果您已经安装了pod，请在项目的

Pods/GoogleMaps/googlemapssdkddemos/SDKDemos/PlacesSamples

目录中查找文件

SDKDemoAutocompleteWithTextFieldController

，或者运行

pod try GoogleMaps

下载示例。

集成您的GPA（Google Places API）。POD文件包括：

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

首先，提供AppDelegate.swift的密钥

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表视图。然后将这些行添加到ViewController.swift文件中，钩住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)
    }
}

//在视图控制器中有TextField和TableView设置

如何从prediction object获取所选地点的坐标？我刚刚实现了这一点，并尝试在加拿大搜索特定地址，但它不起作用。它只显示机场名称或餐厅名称等地名，但不显示具体地址。我如何在这里用您的代码专门填充地址？

import UIKit
import GooglePlaces
import GoogleMaps
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.

////        [GMSPlacesClient provideAPIKey:...]
//        [GMSPlacesClient .provideAPIKey("xxxxxxxxxxxxxxxxxxxxxx")]

        GMSPlacesClient.provideAPIKey("xxxxxxx")
        GMSServices.provideAPIKey("xxxxxxxxxx")

        return true
    }
}
