[英]In Alamofire only the UINavigationController is called! no other response
I am using this tutorial to auto-complete the google places. 我正在使用本教程自动完成Google地方信息。
I have installed the alamofire and swiftyJSON through cocoapads. 我已经通过cocoapads安装了alamofire和swiftyJSON。
My issue is When I enter text in searchbar, nothing happens. 我的问题是,当我在搜索栏中输入文字时,什么也没发生。
On my ViewControlller: 在我的ViewControlller上:
let gpaViewController = GooglePlacesAutocomplete(
apiKey: "MY-API-KEY",
placeType: .Address
)
gpaViewController.placeDelegate = self
presentViewController(gpaViewController, animated: true, completion: nil)
On my GooglePlacesAutoComplete View Controller: 在我的GooglePlacesAutoComplete视图控制器上:
import UIKit
import Alamofire
import SwiftyJSON
enum PlaceType: CustomStringConvertible {
case All
case Geocode
case Address
case Establishment
case Regions
case Cities
var description : String {
switch self {
case .All: return ""
case .Geocode: return "geocode"
case .Address: return "address"
case .Establishment: return "establishment"
case .Regions: return "regions"
case .Cities: return "cities"
}
}
}
struct Place {
let id: String
let description: String
}
protocol GooglePlacesAutocompleteDelegate {
func placeSelected(place: Place)
func placeViewClosed()
}
Only this set of codes is called: 仅将此代码集称为:
class GooglePlacesAutocomplete: UINavigationController {
var gpaViewController: GooglePlacesAutocompleteContainer?
var placeDelegate: GooglePlacesAutocompleteDelegate? {
get { return gpaViewController?.delegate }
set { gpaViewController?.delegate = newValue }
}
convenience init(apiKey: String, placeType: PlaceType = .All) {
let gpaViewController = GooglePlacesAutocompleteContainer(
apiKey: apiKey,
placeType: placeType
)
self.init(rootViewController: gpaViewController)
self.gpaViewController = gpaViewController
let closeButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Stop, target: self, action: "close")
gpaViewController.navigationItem.leftBarButtonItem = closeButton
gpaViewController.navigationItem.title = "Enter Address"
}
func close() {
placeDelegate?.placeViewClosed()
}
}
No indication of this: 没有迹象表明:
class GooglePlaceSearchDisplayController: UISearchDisplayController {
override func setActive(visible: Bool, animated: Bool) {
if active == visible { return }
searchContentsController.navigationController?.navigationBarHidden = true
super.setActive(visible, animated: animated)
searchContentsController.navigationController?.navigationBarHidden = false
if visible {
searchBar.becomeFirstResponder()
} else {
searchBar.resignFirstResponder()
}
}
}
// MARK: - GooglePlacesAutocompleteContainer
class GooglePlacesAutocompleteContainer: UIViewController {
var delegate: GooglePlacesAutocompleteDelegate?
var apiKey: String?
var places = [Place]()
var placeType: PlaceType = .All
convenience init(apiKey: String, placeType: PlaceType = .All) {
self.init(nibName: "GooglePlacesAutocomplete", bundle: nil)
self.apiKey = apiKey
self.placeType = placeType
}
override func viewDidLoad() {
super.viewDidLoad()
let tv: UITableView? = searchDisplayController?.searchResultsTableView
tv?.registerClass(UITableViewCell.self, forCellReuseIdentifier: "Cell")
}
}
Or this: 或这个:
// MARK: - GooglePlacesAutocompleteContainer (UITableViewDataSource / UITableViewDelegate)
extension GooglePlacesAutocompleteContainer: UITableViewDataSource, UITableViewDelegate {
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return places.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = self.searchDisplayController?.searchResultsTableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell?
// Get the corresponding candy from our candies array
let place = self.places[indexPath.row]
// Configure the cell
cell!.textLabel!.text = place.description
cell!.accessoryType = UITableViewCellAccessoryType.DisclosureIndicator
return cell!
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
delegate?.placeSelected(self.places[indexPath.row])
}
}
// MARK: - GooglePlacesAutocompleteContainer (UISearchDisplayDelegate)
extension GooglePlacesAutocompleteContainer: UISearchDisplayDelegate {
func searchDisplayController(controller: UISearchDisplayController, shouldReloadTableForSearchString searchString: String!) -> Bool {
getPlaces(searchString)
return false
}
private func getPlaces(searchString: String) {
let url = "https://maps.googleapis.com/maps/api/place/autocomplete/json"
Alamofire.request(.GET, url).responseJSON { response in
switch response.result {
case .Success(let data):
let json = JSON(data)
let name = json["name"].stringValue
print(name)
case .Failure(let error):
print("Request failed with error: \(error)")
}
}
}
}
Apologies for long code. 对长代码表示歉意。 Am not sure, where I made a mistake. 不确定,我在哪里弄错了。 I also set the delegate for searchBar
in xib I double checked the installation of Cocoapads, Alamofire and SwiftyJson. 我还在searchBar
中为searchBar
设置了searchBar
,我仔细检查了Cocoapads,Alamofire和SwiftyJson的安装。 Can someone please help me? 有人可以帮帮我吗? I'm new to these things.. 我是这些东西的新手。
You Have To Make Object Of UISearchBar Like This... 您必须像这样使UISearchBar对象...
lazy var searchBar : UISearchBar = UISearchBar()
In Did Load 中载
searchBar.delegate = self
