performSegueWithIdentifier註冊後解析不起作用

我正在使用performSegueWithIdentifier並且所有這些設備都可以正常工作，但有一個根本不起作用。performSegueWithIdentifier註冊後解析不起作用

我正在使用Parse.com來註冊用戶，並且我想在他們完成升級後執行一個segue，但是我無法使其工作。我認爲performSegue應在功能是地方signUpViewController

我的代碼：

import UIKit 
import Parse 
import ParseUI 
import Bolts 
import FBSDKCoreKit 
import FBSDKLoginKit 
import FBSDKShareKit 
import CoreLocation 

struct localizacaoActualizada {

    super.viewDidLoad()

    // Se ta loggado 
    var user = PFUser.currentUser() 


    if (user?.username != nil) { 



     // self.performSegueWithIdentifier("aposLogin", sender: self) 


    } 



}

    super.viewDidAppear(true) 

    var user = PFUser.currentUser() 
    self.userLogedIn.text = user?.username

你檢查了signUpViewController-方法被調用？ – Christian

是的，因爲它關閉了viewcontroller並且我使用調試器進行了檢查。 –

在你signUpViewController功能你解僱當前視圖控制器，然後你與發件人爲調用performSegueWithIdentifier你剛剛解僱的視圖控制器。嘗試刪除dismissViewControllerAnimated方法調用

已經嘗試過，沒有成功。我有類似的工作：'logInViewController'。但註冊它不工作= / –

我有同樣的問題。但我設法解決它，但它不是一個完美的解決方案。我所做的就是解僱PFSignUpViewController。

但在此之前，我設置了一個全局變量，在我的情況下稱爲initialSignUp的布爾爲true。一旦控制器被解僱，我檢查了PFLogInViewController的viewDidAppear()方法，如果initialSignUp爲真。如果是這種情況，我將它改回false，然後執行segue。

此替代方法適用於我，我希望我可以幫助您解決您的問題。

我認爲你需要設置loginViewController的signupViewController的委託。像這樣的東西（抱歉，它在迅速，但你可以propably工作了）：

let loginViewController = LoginViewController() 
loginViewController.delegate = self 
loginViewController.signUpController?.delegate = self

，然後，你可以調用下面的方法來關閉該視圖和執行賽格瑞（或其他任何東西）。

func logInViewController(logInController: PFLogInViewController, didLogInUser user: PFUser) { 
    self.dismissViewControllerAnimated(true, completion: nil) 
    self.performSegueWithIdentifier("segueID") 

} 
func signUpViewController(signUpController: PFSignUpViewController, didSignUpUser user: PFUser) -> Void { 
    self.dismissViewControllerAnimated(true, completion: nil) 
    self.performSegueWithIdentifier("segueID") 
}

希望得到這個幫助。它爲我工作。

乾杯，朱利安
