在 Swift 3 中单击文本字段时在表格上搜索 Google 地点视图?

Question

当我单击textField并希望在textField下方显示结果时，如何搜索Google Places。我使用的是 Swift 3.0 版本。有人可以帮助我吗

Answer 1

首先，您需要在项目中安装 GooglePlaces SDK。然后你参考下面的代码。

在斯威夫特 3 中

在应用程序委托中

import UIKit
import CoreData
import GoogleMaps
import GooglePlacePicker
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions 
launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
func setUpGoogleMaps()
return true
}
func setUpGoogleMaps() {
let googleMapsApiKey = "AIzaSyA-kiOBvrR9CNztqutwmKaSLyXIid93K0E"
GMSServices.provideAPIKey(googleMapsApiKey)
GMSPlacesClient.provideAPIKey("AIzaSyA-kiOBvrR9CNztqutwmKaSLyXIid93K0E")
}

在您的视图控制器中，具有文本字段

import UIKit
import GooglePlaces
import GoogleMaps
import GooglePlacePicker
class HotelVC: UIViewController, GMSMapViewDelegate, UITextFieldDelegate {
@IBOutlet weak var YourTextField: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
self.YourTextField.delegate = self
}
func textFieldDidBeginEditing(_ textField: UITextField) {
let acController = GMSAutocompleteViewController()
acController.delegate = self
self.present(acController, animated: true, completion: nil)
}
}

extension viewController: GMSAutocompleteViewControllerDelegate {
func viewController(_ viewController: GMSAutocompleteViewController, didAutocompleteWith place: GMSPlace) {
print("Place name: (place.name)")
print("Place address: (place.formattedAddress ?? "null")")
self.YourTextField.text = place.formattedAddress
print("Place attributions: (String(describing: place.attributions))")
self.dismiss(animated: true, completion: nil)
}
func viewController(_ viewController: GMSAutocompleteViewController, didFailAutocompleteWithError error: Error) {
// TODO: handle the error.
//        print("Error: (error.description)")
self.dismiss(animated: true, completion: nil)
}
// User canceled the operation.
func wasCancelled(_ viewController: GMSAutocompleteViewController) {
print("Autocomplete was cancelled.")
self.dismiss(animated: true, completion: nil)
}
}

您将从所选位置获得位置。试试这段代码。

public func viewController(viewController: GMSAutocompleteViewController, didAutocompleteWithPlace place: GMSPlace) {
var lat = place.coordinate.latitude
var lon = place.coordinate.longitude
print("lat lon",lat,lon)
}
