Question

私は

 // Issue #1 
     let correctedAddress:String! = self.searchResults![(indexPath as NSIndexPath).row].addingPercentEncoding(withAllowedCharacters: CharacterSet.symbols) 
     print(correctedAddress) 
     let url = URL(string: "https://maps.googleapis.com/maps/api/geocode/json?address=\(correctedAddress)&sensor=false") 

     let task = URLSession.shared.dataTask(with: url!) { 
      data, response, error in 

      do { 
       if data != nil{ 
        let dic = try JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.mutableLeaves) as! NSDictionary 

        // Issue #2 
        let results = dic["results"] as! [String: Any] 
        let geometry = results["geometry"] as! [String: Any] 
        let location = geometry["location"] as! [String: Any] 

        let lat = location["lat"] as! Double 
        let lon = location["lng"] as! Double 

        self.delegate.locateWithLongitude(lon, andLatitude: lat) 
       } 
      } 
      catch { 
       print("Error") 
      } 
     } 
     task.resume() 

3迅速な問題＃1に更新するので、いくつかのエラーを拾っているように見える： correctedAddress、一例として、値"%51%75%C3%A9%62%65%63%2C%20%43%61%6E%61%64%61"を返します。それにもかかわらず、何らかの理由でURL定数がゼロに戻り、クラッシュが発生します。

なぜそれがnilを返すのか分かりません。私はURLの中のcorrectedAddressを値%51%75%C3%A9%62%65%63%2C%20%43%61%6E%61%64%61に置き換えることができるので、完全なURLは

let url = NSURL(string: "https://maps.googleapis.com/maps/api/geocode/json?address=%51%75%C3%A9%62%65%63%2C%20%43%61%6E%61%64%61&sensor=false")となります。

問題＃2： それはどの私はCould not cast value of type '__NSArrayI' (0x108bb0c08) to 'NSDictionary' (0x108bb1108).

Answer 1

のエラーはあなたの問題＃問題＃1の2

let results = dic["results"] as! NSArray 
for result in results { 
    let strObj = result as! NSDictionary 
    let geometry = strObj["geometry"] as! NSDictionary 
    let location = geometry["location"] as! NSDictionary 
    let lat = location["lat"] as! NSNumber 
    let lon = location["lng"] as! NSNumber 
} 

については、以下のコードを試してみてください取り戻すためにlet resultsでちょうどクラッシュ、してみてくださいコード

let valueAtIndex = self.searchResults![(indexPath as NSIndexPath).row].addingPercentEncoding(withAllowedCharacters: CharacterSet.symbols) 
guard let correctedAddress = valueAtIndex else { return } 
let adrString:String = "https://maps.googleapis.com/maps/api/geocode/json?address=\(correctedAddress)&sensor=false" 
let url:URL = URL(string: adrString)!
