        let task = URLSession.shared.dataTask(with: request as URLRequest) { data , response , error in

            do {

                let err: NSError? let json = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as? NSDictionary

                print(json as Any)

                if let parseJSON = json { let resultValue = parseJSON["status"] as? String print ("result:(resultValue)")

                    var isUserRegister:Bool = false if resultValue == "success" {isUserRegister = true}

                    var messageToDisplay:String = parseJSON["massage"] as! String if isUserRegister {

                        messageToDisplay = parseJSON["massage"] as! String

                    }

                }

            } catch {

                print("error")
            }
        }
    }
}

这是错误

我使用Swift 3语法修复了你的代码。

class SignUp: UIViewController {

@IBOutlet weak var buttonNameTxt: UITextField!
@IBOutlet weak var buttonEmailTxt: UITextField!
@IBOutlet weak var buttonPwdTxt: UITextField!

override func viewDidLoad() {
    super.viewDidLoad()
}

@IBAction func buttonSignIn(_ sender: UIButton) {

    let usermainname = buttonNameTxt.text!
    let username = buttonEmailTxt.text!
    let password = buttonPwdTxt.text!

    let myURL = URL(string: "https://mev.com/api/login")
    let request = NSMutableURLRequest(url: myURL!)
    request.httpMethod = "Post"

    let postString = "name = \(usermainname) email = \(username) &passwod = \(password)"
    request.httpBody = postString.data(using: String.Encoding.utf8)

    let task = URLSession.shared.dataTask(with: request as URLRequest) { data , response , error in

        do {
            if let json = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as? NSDictionary {

                let resultValue = json["status"] as? String
                print("result: \(resultValue)")

                if resultValue == "success", let messageToDisplay = json["massage"] as? String {
                    print("\(messageToDisplay)")
                }
            }

        } catch {

            print("error")
        }
    }
    task.resume()
}
}

Swift 3代码更新
