【问题描述】：

我正在尝试将用户为注册页面输入的信息存储到解析数据库中，但似乎不知道该怎么做。

class ViewController: UIViewController 

@IBOutlet var fullnameField: UITextField!
@IBOutlet var emailAddressField: UITextField!
@IBOutlet var usernameField: UITextField!
@IBOutlet var passwordField: UITextField!

override func viewDidLoad() 
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    let userFullname = fullnameField.text
    let userEmailAddress = emailAddressField.text
    let userName = usernameField.text
    let userPassword = passwordField.text


    let User = PFObject(className: "User")
    User["FullName"] = "Example Name"
    User["EmailAddress"] = "[e-mail]"
    User["Username"] = "Example"
    User["Password"] = "Ilovesmores12345"
    User.saveInBackgroundWithBlock  (success: Bool, error: NSError?) -> Void in
        println("Object has been saved.")
    



override func didReceiveMemoryWarning() 
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.

当用户在文本字段中输入他/她的信息并点击注册时，我需要将信息保存到解析数据库中，以便在登录页面上进一步使用。我觉得我想多了，让它变得更复杂了，有没有办法轻松做到这一点？

【参考方案1】：

注册时不要使用user.save - 使用user.signUpInBackgroundWithBlock

检查this link，它是 Parse ios 指南。

我的示例，创建一个按钮并将其连接到signUpPressed 方法。方法如下。

 @IBAction func signUpPressed(sender: AnyObject) 

    let userName = userNameField.text
    let email = emailField.text.lowercaseString
    let password = passwordField.text
    let fullName = fullNameField.text

    var user = PFUser()
    user.username = userName
    user.email = email
    user.password = password

    //for custom fields use default key-value assign
    user["fullName"] = fullName

    user.signUpInBackgroundWithBlock (succeeded: Bool, error: NSError?) -> Void in
      if let error = error 
        let errorString = error.userInfo?["error"] as? String
        // Show the errorString somewhere and let the user try again.
       else 
       // Hooray! Let them use the app now.
      
    
  

我建议您以小写字母开头来命名对象的字段，以免与类名混淆。

【讨论】：

如果我单击链接并转到用户 > 注册...如何将文本字段与这些值连接？它让我有点困惑。我只是复制粘贴的确切代码，现在如何将其连接到文本字段？
