Как создать класс RequestManager без использования фреймворков swift

Question

Я создал 5 классов, которые включают ProfileHomeModel, ProfileLocationModel, ProfileRequestManager, ProfileTableUserViewController и ProfileTableViewCell. Моя цель - правильно проанализировать json и отобразить данные. У меня возникла проблема в классе диспетчера запросов. Я совершенно новый, быстрый. Я хотел бы сделать это без использования swiftyJSON и Alamofire.

import Foundation 
class ProfileRequestManager{ 


    let urlPath = "*********" 

    let url = NSURL(string: urlPath) 
    let data = NSData(contentsOfURL: url!) 

    do { 
     let jsonData = try NSJSONSerialization.JSONObjectWithData(data!, options: .AllowFragments) as? NSDictionary 

     print(jsonData) 
     let results = jsonData!.objectForKey("strengths") as? [NSDictionary] ?? [] 

    for result in results { 
     print(result) 
    } 


    } 
    catch { 
     print("Something went wrong while parsing json data fetched from the API") 
    } 


} 

jsonData

{ "success": true, "profile": { "firstname": "Vignesh", "lastname": "Krish", "title": "Software Developer Intern", "designations": null, "specialty": "Computer Science", "location": "0", "email": "vignesh@ampthealth.com", "phone": "4026136265", "biography": "Boxing and Travelling", "interests": "Watching movies", "skills": "Hozier and A.R Rahman", "goals": "becoming a software developer", "mentors": "Hardik Patel", "doh": "2016-05-09", "dob": "1994-06-08", "strengths": [ { "id": "4", "name": "Analytical", "description": "People exceptionally talented in the Analytical theme search for reasons and causes. They have the ability to think about all the factors that might affect a situation.", "color": "9c0000" }, { "id": "17", "name": "Focus", "description": "People exceptionally talented in the Focus theme can take a direction, follow through, and make the corrections necessary to stay on track. They prioritize, then act.", "color": "5c3a6e" }, { "id": "8", "name": "Communication", "description": "People exceptionally talented in the Communication theme generally find it easy to put their thoughts into words. They are good conversationalists and presenters.", "color": "da892f" }, { "id": "29", "name": "Responsibility", "description": "People exceptionally talented in the Responsibility theme take psychological ownership of what they say they will do. They are committed to stable values such as honesty and loyalty.", "color": "5c3a6e" }, { "id": "30", "name": "Restorative", "description": "People exceptionally talented in the Restorative theme are adept at dealing with problems. They are good at figuring out what is wrong and resolving it.", "color": "5c3a6e" } ], "settings": { "enable_sms": "0" } } }

Я пытаюсь вернуть все это выше

погрешность я получаю от делать улова. Xcode дает мне ожидаемую ошибку объявления. Я проверил свои фигурные скобки.

Поблагодарили бы за помощь в этом.

Кроме того, мне не нужно указывать URL-адрес в целях безопасности. Я надеюсь, что это помогает.

Я также пытаюсь отобразить все значения в отдельных ячейках. Это то, что у меня есть сейчас.

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 


    if indexPath.row == 0 { 

     let cell = tableView.dequeueReusableCellWithIdentifier("ProfileCell", forIndexPath: indexPath) as! ProfileUserTableViewCell 
     cell.firstName?.text = firstName 
     cell.lastName?.text = lastName 
     cell.title?.text = title 

     return cell 

} 
} 

Знаете ли вы, как я могу это исправить?

это моя текущая ситуация. Я не могу заставить его отображать ячейки таблицы. Проблема заключается в том, как я присваиваю значения json ярлыкам.

Вот небольшая попытка того, что вы можете сделать, чтобы сериализовать JSON. Я реализовал следующий код внутри блока viewDidLoad() для успешной печати данных json в консоли xcode.

let requestURL: NSURL = NSURL(string: "https://*******************")! 
    //Your baseURL 
    let urlRequest: NSMutableURLRequest = NSMutableURLRequest(URL: requestURL) 
    let session = NSURLSession.sharedSession() 
    let task = session.dataTaskWithRequest(urlRequest) { 
     (data, response, error) -> Void in 

     let httpResponse = response as! NSHTTPURLResponse 
     let statusCode = httpResponse.statusCode 

     if (statusCode == 200) { 
      print("Everyone is fine") 

      do { 
       let JSON = try NSJSONSerialization.JSONObjectWithData(data!, options:NSJSONReadingOptions(rawValue: 0)) 
       guard let JSONDictionary :NSDictionary = JSON as? NSDictionary else { 
        print("Not a Dictionary") 

        return 
       } 
       // print("JSONDictionary! \(JSONDictionary)") 

       if let profile = JSONDictionary["profile"] as? NSDictionary { 
        print(profile) 


        //This is where we should begin parsing json into whatever you want to 

      let biography = profile["biography"] as? String 
        let designations = profile["designations"] as? String 
        let dob = profile["dob"] as? String 
        let doh = profile["doh"] as? String 
        let email = profile["email"] as? String 
        // do the same for firstname, goals, interests, lastname, location, mentors, phone, skills, speciality 

        print(biography!, designations, dob!) 

        let settings = profile["settings"] as? NSDictionary 

         let enableSMS = settings!.valueForKey("enable_sms") as? String 
         print(enableSMS!) 

        let strengths = profile["strengths"] as? NSArray 
        for eachItem in strengths! { 
         let color = eachItem.valueForKey("color") as? String 
         let description = eachItem.valueForKey("description") 
         let id = eachItem.valueForKey("id") 
         let name = eachItem.valueForKey("name") 
         print(name!, description!, color!, id!) 
        } 




       } 
      } 
      catch let JSONError as NSError { 
       print("\(JSONError)") 
      } 



     } 
    } 

    task.resume() 

Надеюсь, это вам поможет. Играйте с массивами и словарями, и вы сможете вытащить все значения из вашего API.
