Facebook登錄iOS SDK被卡在「Confirm」

Question

有沒有人遇到過這個問題？按下登錄按鈕並啓動該過程後，用戶將卡在此屏幕上，您應在其中啓用或確認應用程序的權限。但是，這裏沒有什麼可做的。

In appdelegate: 

import FacebookCore 

func application(_ application: UIApplication, 
        didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 
    SDKApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions) 

    return true 
} 

func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool { 
    return SDKApplicationDelegate.shared.application(application, 
                open: url, 
                sourceApplication: sourceApplication, 
                annotation: annotation) 
} 


@available(iOS 9.0, *) 
func application(_ application: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any]) -> Bool { 
    return SDKApplicationDelegate.shared.application(application, open: url, options: options) 
} 

func applicationDidBecomeActive(_ application: UIApplication) { 
    AppEventsLogger.activate(application) 
} 


In View Controller 

import FacebookCore 
import FacebookLogin 


func facebookLogin() { 
    let loginManager = LoginManager() 
    loginManager.logIn([ .email ], viewController: self) { (loginResult) in 
     switch loginResult { 
     case .failed(let error): 
      print(error) 
     case .cancelled: 
      print("User cancelled login.") 
     case .success(let grantedPermissions, let declinedPermissions, let accessToken): 
      print("Logged in \(grantedPermissions) \(declinedPermissions) \(accessToken)") 
     } 
    } 
} 

And if you have multiple social login like facebook login and google signin 

func application(_ application: UIApplication, 
       open url: URL, sourceApplication: String?, annotation: Any) -> Bool { 

    var _: [String: AnyObject] = [UIApplicationOpenURLOptionsKey.sourceApplication.rawValue: sourceApplication as AnyObject, 
             UIApplicationOpenURLOptionsKey.annotation.rawValue: annotation as AnyObject] 

    if url.absoluteString.contains("facebook") { 
     return SDKApplicationDelegate.shared.application(application, 
                 open: url, 
                 sourceApplication: sourceApplication, 
                 annotation: annotation) 
    }else{ 
     return GIDSignIn.sharedInstance().handle(url as URL!, 
               sourceApplication: sourceApplication, 
               annotation: annotation) 
    } 
} 

上述編輯應該工作。
