ios - 解析登录和注册功能 SWIFT

Question

所以我一直遇到的问题是，我正在观看教程，当我将其放入下面的代码行时，它会自动使其成为一个函数。对我来说，当我输入它时，我得到的只是

logInViewController(logInController: PFLogInViewController!, shouldBeginLogInWithUsername: String!, password: String!)

这不是一个函数。所以我尝试通过在开头添加 func 并在结尾添加 {} 来使其成为一个函数(请看下面)

func logInViewController(logInController: PFLogInViewController!, shouldBeginLogInWithUsername: String!, password: String!){

    }

一切正常，但是当我添加下一个时(如下所示)

func logInViewController(logInController: PFLogInViewController!, didLogInUser: PFUser!){

    }

我收到错误“定义与之前的值冲突”，我是否可以只更改函数的名称，一切都会好起来？因为在视频中我看到他们不需要改名字。

那么我怎样才能让它正常工作而不出现错误。

这是案例中的所有代码

import UIKit
import Parse
import ParseUI



class homeViewController: UIViewController, PFLogInViewControllerDelegate, PFSignUpViewControllerDelegate {







//These are all Buttons--------------
@IBAction func emailB(sender: UIButton) {
    println("Email View : Pressed : Working")

}


@IBAction func EstimatorB(sender: UIButton) {
    println("Estimator View : Pressed : Working")
    let viewEstimator: AnyObject! = self.storyboard!.instantiateViewControllerWithIdentifier("EstimatorScreen")
    viewEstimator
}
//====================================

//Login Screen Pop-up-----------------
override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)


    if (PFUser.currentUser() == nil){

        var LogInViewController : PFLogInViewController! = PFLogInViewController()


        LogInViewController.delegate = self

        var signUpViewController: PFSignUpViewController! = PFSignUpViewController()

        signUpViewController.delegate = self

        LogInViewController.signUpController = signUpViewController

        self.presentViewController(LogInViewController, animated: true, completion: nil)


    }
//=======================================






//To go to another screen
//let viewHome = self.storyboard?.instantiateViewControllerWithIdentifier("HomeScreen")

// IGNOR THIS CODE-------=======================
 func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.
}

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


//MARK : Login 
    func logInViewController(logInController: PFLogInViewController!, shouldBeginLogInWithUsername: String!, password: String!){

    }

     func logInViewController(logInController: PFLogInViewController!, didLogInUser: PFUser!){

    }

     func logInViewController(logInController: PFLogInViewController, didFailToLogInWithError: NSError!){

    }


//MArK : SignUp

     func signUpViewController(signUpController: PFSignUpViewController, shouldBeginSignUp: [NSObject : AnyObject]){

    }

     func signUpViewController(signUpController: PFSignUpViewController, didSignUpUser: PFUser){

    }

    func  signUpViewController(signUpController: PFSignUpViewController, didFailToSignUpWithError: NSError?){

    }







}

}

如果您不想为您进行登录/注册而头痛地进行解析...这里有一个很棒的教程，它将逐步引导您完成自定义的操作。这很简单。我最终没有使用他们的，因为它不断给我带来所有错误。 https://medium.com/swift-programming/ios-swift-parse-com-part-3-sign-up-sign-in-sign-out-security-349adc94ef0e
