[英]preferredInterfaceOrientationForPresentation only called once in iOS7 with subclass of UINavigationController
[英]In Alamofire only the UINavigationController is called! no other response
我正在使用本教程自動完成Google地方信息。
我已經通過cocoapads安裝了alamofire和swiftyJSON。
我的問題是,當我在搜索欄中輸入文字時,什么也沒發生。
在我的ViewControlller上:
let gpaViewController = GooglePlacesAutocomplete(
apiKey: "MY-API-KEY",
placeType: .Address
)
gpaViewController.placeDelegate = self
presentViewController(gpaViewController, animated: true, completion: nil)
在我的GooglePlacesAutoComplete視圖控制器上:
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()
}
僅將此代碼集稱為:
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()
}
}
沒有跡象表明:
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")
}
}
或這個:
// 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)")
}
}
}
}
對長代碼表示歉意。 不確定,我在哪里弄錯了。 我還在searchBar
中為searchBar
設置了searchBar
,我仔細檢查了Cocoapads,Alamofire和SwiftyJson的安裝。 有人可以幫幫我嗎? 我是這些東西的新手。
您必須像這樣使UISearchBar對象...
lazy var searchBar : UISearchBar = UISearchBar()
中載
searchBar.delegate = self
