谷歌的地方自動完成IOS迅速用的UITextField

Question

我想實現谷歌通過以下庫放置在SWIFT 2.0項目自動完成API集成：

https://github.com/watsonbox/ios_google_places_autocomplete

我不能夠想出的唯一的事情是我想與我的應用程序窗體中有uitextfield這個有國家和城市領域。

我已經在一個演示項目中實現了這個應用程序，並且發現它也提供了我長期的位置。

請幫我指導我整合此庫與uitextfield，因此當用戶輸入uitextfield時，結果僅顯示在uitextfield的下方。

通過合作來實現在演示應用程序代碼中，我才知道，在搜索框打開了下面的代碼：

let gpaViewController = GooglePlacesAutocomplete(
     apiKey: "API KEY FROM GOOGLE PLACES API", 
     placeType: .Address 
    ) 

我無法弄清楚如何得到這個viewcontroller功能的工作對我uitextfield因此它可以正常工作uitextfield

爲什麼不使用適用於iOS的Google Places API？它具有上述庫中所見的所有功能。這裏是鏈接https://developers.google.com/places/ios-api/autocomplete

並且您可以使用fetcher對象來獲取預測結果，並根據需要自定義結果。希望這有助於

谷歌的自動完成API使用搜索欄

1）

let googleAutoCompeteApi = "https://maps.googleapis.com/maps/api/place/autocomplete/json?input=%@&types=establishment|geocode&location=%@,%@&radius=500&language=en&key=%@" 
var arrPlaces = NSMutableArray(capacity: 100) 
let operationQueue = NSOperationQueue() 
let googleServerkey = "Your API KEY" 

2）

func searchBar(searchBar: UISearchBar, textDidChange searchText: String) { 
     self.beginSearching(searchText) 
    } 

    func beginSearching(searchText:String) { 
     if searchText.characters.count == 0 { 
      self.arrPlaces.removeAllObjects() 
      self.tblOfflineCity.reloadData() 
      return 
     } 

     operationQueue.addOperationWithBlock {() -> Void in 
      self.forwardGeoCoding(searchText) 
     } 
    } 

    //MARK: - Search place from Google - 
    func forwardGeoCoding(searchText:String) { 
     googlePlacesResult(searchText) { (result) -> Void in 
      let searchResult:NSDictionary = ["keyword":searchText,"results":result] 
      if result.count > 0 
      { 
       let features = searchResult.valueForKey("results") as! [AnyObject] 
       self.arrPlaces = NSMutableArray(capacity: 100) 
       for dictAddress in features { 
        self.arrPlaces.addObject(dictAddress.valueForKey("description")!) 
       } 
       dispatch_async(dispatch_get_main_queue(), { 
        self.tblOfflineCity.reloadData() 
       }); 
      } 
     } 
    } 

    //MARK: - Google place API request - 
    func googlePlacesResult(input: String, completion: (result: NSArray) -> Void) { 
     let searchWordProtection = input.stringByReplacingOccurrencesOfString(" ", withString: "") 
     if searchWordProtection.characters.count != 0 { 
      let urlString = NSString(format: googleAutoCompeteApi,input,currentLat,currentLong,googleServerkey) 
      let url = NSURL(string: urlString.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)!) 
      let defaultConfigObject = NSURLSessionConfiguration.defaultSessionConfiguration() 
      let delegateFreeSession = NSURLSession(configuration: defaultConfigObject, delegate: nil, delegateQueue: NSOperationQueue.mainQueue()) 
      let request = NSURLRequest(URL: url!) 
      let task = delegateFreeSession.dataTaskWithRequest(request, 
                   completionHandler: { 
                    (data, response, error) -> Void in 
                    if let data = data { 

                     do { 
                      let jSONresult = try NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.AllowFragments) as! [String:AnyObject] 
                      let results:NSArray = jSONresult["predictions"] as! NSArray 
                      let status = jSONresult["status"] as! String 

                      if status == "NOT_FOUND" || status == "REQUEST_DENIED" { 

                       let userInfo:NSDictionary = ["error": jSONresult["status"]!] 
                       let newError = NSError(domain: "API Error", code: 666, userInfo: userInfo as [NSObject : AnyObject]) 
                       let arr:NSArray = [newError] 
                       completion(result: arr) 
                       return 
                      } else { 
                       completion(result: results) 
                      } 
                     } 
                     catch { 
                      print("json error: \(error)") 
                     } 
                    } else if let error = error { 
                     print(error.description) 
                    } 
      }) 
      task.resume() 
     } 
    } 

你會得到導致self.arrPlaces 。要在uitextField中使用，只需要使用uitextField委託而不是搜索欄調用函數
