| swiftでのデータ引き継ぎの画面遷移 |
| ###前提・実現したいこと |
| postでjsonデータを次の画面に引き継ぎたいのですが、上手くいきません。 |
| LoginControllerのresultDataに、postで受けっとたJSONデータを格納して、 |
| Userontrollerのparamsにデータを渡して、UserControllerの方にpostで受けっとたJSONデータを表示させたいのですが、 |
| 以下のようにコードを作成したのですが、上手くいきません。 |
| ```LoginViewController.swift |
| // LoginViewController.swift |
| import UIKit |
| class LoginViewController: UIViewController, UITextFieldDelegate { |
| @IBOutlet weak var email: UITextField! |
| @IBOutlet weak var password: UITextField! |
| @IBOutlet weak var password_confirmation: UITextField! |
| var resultData:String = "" |
| override func viewDidLoad() { |
| super.viewDidLoad() |
| email.delegate = self |
| password.delegate = self |
| password_confirmation.delegate = self |
| } |
| func textFieldShouldReturn(_ textField: UITextField) -> Bool{ |
| if (textField == email) { |
| password?.becomeFirstResponder() |
| } else if (textField == password) { |
| password_confirmation?.becomeFirstResponder() |
| }else{ |
| // キーボードを閉じる |
| textField.resignFirstResponder() |
| } |
| return true |
| } |
| override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?){ |
| if(email.isFirstResponder || password.isFirstResponder || password_confirmation.isFirstResponder){ |
| email.resignFirstResponder() |
| password.resignFirstResponder() |
| password_confirmation.resignFirstResponder() |
| } |
| } |
| @IBAction func backButton(_ sender: Any) { |
| dismiss(animated: true, completion: nil) |
| } |
| @IBAction func LoginButton(_ sender: Any) { |
| let emailText:String = self.email.text! |
| let passwordText:String = self.password.text! |
| let password_confirmationText:String = self.password_confirmation.text! |
| let urlString = "" |
| let request = NSMutableURLRequest(url: NSURL(string: urlString)! as URL) |
| request.httpMethod = "POST" |
| request.addValue("application/json", forHTTPHeaderField: "Content-Type") |
| let params: [String: AnyObject] = [ |
| "email": emailText as AnyObject, |
| "password": passwordText as AnyObject, |
| "password_confirmation": password_confirmationText as AnyObject |
| ] |
| do{ |
| request.httpBody = try JSONSerialization.data(withJSONObject: params, options: .prettyPrinted) |
| let task:URLSessionDataTask = URLSession.shared.dataTask(with: request as URLRequest, completionHandler: {(data,response,error) -> Void in |
| self.resultData = String(data: data!, encoding: .utf8)! |
| print("result:\(self.resultData)") |
| print("response:\(String(describing: response))") |
| }) |
| task.resume() |
| }catch{ |
| print("Error:\(error)") |
| return |
| } |
| } |
| // MARK: - Navigation |
| override func prepare(for segue: UIStoryboardSegue, sender: Any?) { |
| if (segue.identifier == "touserinfo") { |
| let UserViewController = segue.destination as! UserViewController |
| UserViewController.params = self.resultData |
| } |
| } |
| override func didReceiveMemoryWarning() { |
| super.didReceiveMemoryWarning() |
| } |
| } |
| ``` |
| ```UserViewController.swift |
| // |
| // UserViewController.swift |
| import UIKit |
| class UserViewController: UIViewController { |
| @IBOutlet weak var label: UILabel! |
| var params: String = "" |
| override func viewDidLoad() { |
| super.viewDidLoad() |
| label.text = params |
| print("JSON_User_info: \(params)") |
| } |
| @IBAction func backButton(_ sender: Any) { |
| dismiss(animated: true, completion: nil) |
| } |
| override func didReceiveMemoryWarning() { |
| super.didReceiveMemoryWarning() |
| } |
| } |
| ``` |
| ご教授お願いいたします。 |
