Swift: Firebase ile otomatik giriş yap Kullanıcı

Question

Zaten oturum açmışsa ve sadece ana görünüme gidiyorsa ancak kod iki kez çalışıyorsa otomatik olarak oturum açmak istiyorum ve sadece gösterme görünümü yerine aktarmayı görebilirsiniz. Nasıl düzeltebilirim?

AppDelegate.swift

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { 
    // Override point for customization after application launch.slideMenuController 
    FIRApp.configure() 
    FIRAuth.auth()?.addAuthStateDidChangeListener { 
     auth, user in 
     if user != nil { 
      // User is signed in. 
      print("Automatic Sign In: \(user?.email)") 

      let storyboard = UIStoryboard(name: "Main", bundle: nil) 
      let initialViewController = storyboard.instantiateViewControllerWithIdentifier("EmployeeRevealViewController") 
      self.window!.rootViewController = initialViewController 

     } else { 
      // No user is signed in. 
     } 
    } 

    return true 
}

Answer 1

Dene: güncellenmiş belgeler gelince

if let alreadySignedIn = FIRAuth.auth()?.currentUser { 
    // segue to main view controller 
} else { 
    // sign in 
} 

Answer 2

, bu Firebase belgelere dayanarak bunu yapmak için recommened yoludur ve benim için çalıştı:

if Auth.auth().currentUser != nil { 
    // User is signed in. 
    // ... 
} else { 
    // No user is signed in. 
    // ... 
} 

Firebase en noticably onların adlandırma kuralı ama değişti:

FIRAuth En iyi sonuçlar için de

Auth olarak değiştirildi var, böyle viewDidAppear() içime koydu:

Firebase 4 ve hızlı 4 kişilik tanımlayıcı olmadan

Answer 3

override func viewDidAppear(_ animated: Bool) { 
    super.viewDidAppear(true) 
    if Auth.auth().currentUser != nil { 
     performSegue(withIdentifier: "yourIdentifier", sender: self) 
    } 
} 

, bu ... benim için iyi çalıştı

override func viewDidAppear(_ animated: Bool) { 
    super.viewDidAppear(true) 
    if Auth.auth().currentUser != nil { 
     let newViewController: YourViewController = YourViewController() 
     self.present(newViewController, animated: true, completion: nil) 
    } 
}
