Facebook SDKログインを使用して、あるストーリーボードから別のストーリーボードに移動します

Facebookアプリを作成してセットアップしましたか？あなたはここでそれを行うことができますhttps://developers.facebook.com/apps/：

• アプリの作成>表示名の設定>アプリIDの作成
• then you need to go to Settings > Basic > scroll down till you see Add Platform and choose iOS
• put the bundle id of your iOS Project (that you can find in your Xcode > Project > Target > Bundle Identifier) and enable Single Sign ON then do Save Changes
• Roles > Test Users > Add > Create Test User > Edit > Change name/password and put a password you will remember

Take note now of the test email user and password so you can debug your app. In Settings > Basic take note of App ID and Display Name to put in your Info.plist later.

Make sure you added to your Podfile:

pod 'FacebookCore'
pod 'FacebookLogin'

Then do a pod install in terminal (if you haven't already installed both pods).

In your AppDelegate.swift you should have this at least:

import UIKit
import FacebookLogin

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

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

        ApplicationDelegate.shared.application(
            application,
            didFinishLaunchingWithOptions:
            launchOptions
        )

        return true
    }

    func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
        return ApplicationDelegate.shared.application(
            app,
            open: url,
            options: options
        )
    }
}

Right click on Info.plist and Open As > Source Code, paste this before </dict> :

<key>CFBundleURLTypes</key>
<array>
  <dict>
    <key>CFBundleURLSchemes</key>
    <array>
      <string>fb{your-app-id}</string>
    </array>
  </dict>
</array>
<key>FacebookAppID</key>
<string>{your-app-id}</string>
<key>FacebookDisplayName</key>
<string>{your-app-name}</string>
<key>LSApplicationQueriesSchemes</key>
<array>
  <string>fbapi</string>
  <string>fb-messenger-share-api</string>
  <string>fbauth2</string>
  <string>fbshareextension</string>
</array>

And substitute {your-app-name} (once, with the Display App Name you took note before from your Facebook App Dashboard) and {your-app-id} (twice, as well you took note of this in the first step from your Facebook App Dashboard) in the above snippet.

Now go to your ViewController.swift:

import UIKit
import FacebookLogin

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        if AccessToken.current != nil {
            // Already logged-in
            // Redirect to Home View Controller
            goToHome()
        }

        // Add LoginButton
        let loginButton = FBLoginButton(permissions: [ .publicProfile, .email, .userFriends ])
        let screenSize:CGRect = UIScreen.main.bounds
        let screenHeight = screenSize.height // real screen height
        //let's suppose we want to have 10 points bottom margin
        let newCenterY = screenHeight - loginButton.frame.height - 20
        let newCenter = CGPoint(x: view.center.x, y: newCenterY)
        loginButton.center = newCenter
        view.addSubview(loginButton)

        // Triggered after every successfully login / logout
        NotificationCenter.default.addObserver(forName: .AccessTokenDidChange, object: nil, queue: OperationQueue.main) { [weak self] _ in
            if AccessToken.current != nil {
                // Successfully just Logged in
                // Redirect to Home View Controller
                self?.goToHome()
            } else {
                // Successfully just Logged out
            }
        }
    }

    func goToHome() {
        let storyboard = UIStoryboard(name: "HomeAfterLogIn", bundle: nil)
        let vc = storyboard.instantiateViewController(withIdentifier: "HomeAfterLogInViewController") // I called mine like that (check screenshot below)
        self.navigationController?.pushViewController(vc, animated: true)
    }

}

Make sure your HomeAfterLogIn.storyboard's ViewController (which I am not sure with what ***ViewController.swift you linked it) has a HomeAfterLogIn Stoyboard ID. Eventually it should also be linked to a ***ViewController.swift file having the same name as the ID for simplicity (HomeAfterLogIn.swift for example).

私の例でHomeAfterLogInViewControllerは、このスクリーンショットにHomeAfterLogInViewController.swift示されているように、ファイルとHomeAfterLogInViewControllerの両方を呼び出しましたStoryboard IDが、ストーリーボードのファイル名はHomeAfterLogIn.storyboard。のままにしました。

あなたを埋め込むなかった場合はViewController内Main.storyboardに（私はあなたがそれをそこに持っていると思います）NavigationController、あなたはそれがナビゲーションにプッシュ動作させるためにそれをしなければならない、このようなホーム...のViewControllerとして別のViewControllerをスタック。

次のように実行できます。Main.storyboardからViewControllerをクリックし、メニューで次の場所に移動しEditor > Embed In > Navigation Controllerます。
