facebook-login mit swift 3

bitte helfen Sie mir mit Facebook login

Habe ich begonnen, mit der Inbetriebnahme der pod

pod 'FacebookCore'
pod 'FacebookLogin'
pod 'FacebookShare'
and then run pod install

nach dieser habe ich importiert diese in meine viewController

import UIKit
import FacebookCore
import FacebookLogin

class ViewController: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()
    //Do any additional setup after loading the view, typically from a nib.
    let loginButton = LoginButton(readPermissions: [ .publicProfile ])
    loginButton.center = view.center
    view.addSubview(loginButton)
}

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


}

Ich aktualisiert info.plist mit Facebook-Daten

wie bekomme ich user-basic Profil Daten wenn der Benutzer berechtigt hat, die app?
Was geht in AppDelegate-Datei?

Dank

    Hier ist der code für den login die facebook von einem UIButton klicken.

    Schritt 1: Kopieren Sie diesen code in ur-class-Datei

    import UIKit
import FBSDKShareKit
import FBSDKLoginKit
import FBSDKCoreKit

class Facebook_loginPageViewController: UIViewController {

   override func viewDidLoad() {
       super.viewDidLoad()
   }

   override func didReceiveMemoryWarning(){
      super.didReceiveMemoryWarning()
   }


   @IBAction func login(_ sender: Any) {
      self.facebooklogin()
   }


   func facebooklogin() {
      let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
      fbLoginManager.logIn(withReadPermissions: ["email"], handler: { (result, error) -> Void in

      print("\n\n result: \(result)")
      print("\n\n Error: \(error)")

      if (error == nil) {
        let fbloginresult : FBSDKLoginManagerLoginResult = result!
        if(fbloginresult.isCancelled) {
           //Show Cancel alert
        } else if(fbloginresult.grantedPermissions.contains("email")) {
            self.returnUserData()
            //fbLoginManager.logOut()
        }
       }
     })
    }


    func returnUserData() {
       let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"email,name"])
       graphRequest.start(completionHandler: { (connection, result, error) -> Void in
          if ((error) != nil) {
              //Process error
              print("\n\n Error: \(error)")
           } else {
                 let resultDic = result as! NSDictionary
                 print("\n\n  fetched user: \(result)")
                 if (resultDic.value(forKey:"name") != nil) {
                     let userName = resultDic.value(forKey:"name")! as! String as NSString?
                     print("\n User Name is: \(userName)")
                  }

                 if (resultDic.value(forKey:"email") != nil) {
                     let userEmail = resultDic.value(forKey:"email")! as! String as NSString?
                     print("\n User Email is: \(userEmail)")
                  }
             }
        })
     }
}

    Schritt 2: In AppDelegate fügen Sie die id des facebook

    import UIKit
import FBSDKShareKit
import FBSDKLoginKit
import FBSDKCoreKit

class AppDelegate: UIResponder, UIApplicationDelegate {

    func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
        let str_URL = url.absoluteString as NSString
        if str_URL.contains("fb1111111111111111")//put you id here {
           return FBSDKApplicationDelegate.sharedInstance().application(
                    app,
                    open: url as URL!,
                    sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String,
                    annotation: options[UIApplicationOpenURLOptionsKey.annotation])
          }


           return FBSDKApplicationDelegate.sharedInstance().application(
                app,
                open: url as URL!,
                sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String,
                annotation: options[UIApplicationOpenURLOptionsKey.annotation])

        }
}

    Schritt 3: fügen Sie diesen code in " info.plist'

    <key>CFBundleURLTypes</key>
     <array>
         <dict>
             <key>CFBundleURLSchemes</key>
             <array>
                 <string>fb1111111111111111</string>
             </array>
         </dict>


     </array>
     <key>CFBundleVersion</key>
        <string>2</string>
     <key>FacebookAppID</key>
        <string>1111111111111111</string>
     <key>FacebookDisplayName</key>
        <string>Together Deal</string>
     <key>LSApplicationQueriesSchemes</key>
        <array>
            <string>fbapi</string>
            <string>fb-messenger-api</string>
            <string>fbauth2</string>
            <string>fbshareextension</string>
        </array>
    • Statt 1111111111111111 fügen Sie Ihre fb-App-ID.

    Hier ist der code von

    1. ViewController.swift

    import UIKit

import FacebookLogin
import FBSDKLoginKit

class ViewController: UIViewController {

    var dict : [String : AnyObject]!

    override func viewDidLoad() {
        super.viewDidLoad()

        //creating button
        let loginButton = LoginButton(readPermissions: [ .publicProfile ])
        loginButton.center = view.center

        //adding it to view
        view.addSubview(loginButton)

        //if the user is already logged in
        if let accessToken = FBSDKAccessToken.current(){
            getFBUserData()
        }

    }

    //when login button clicked
    @objc func loginButtonClicked() {
        let loginManager = LoginManager()
        loginManager.logIn([ .publicProfile ], 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):
                self.getFBUserData()
            }
        }
    }

    //function is fetching the user data
    func getFBUserData(){
        if((FBSDKAccessToken.current()) != nil){
            FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, picture.type(large), email"]).start(completionHandler: { (connection, result, error) -> Void in
                if (error == nil){
                    self.dict = result as! [String : AnyObject]
                    print(result!)
                    print(self.dict)
                }
            })
        }
    }
}

    2. AppDelegate.swift

    import UIKit
import FBSDKLoginKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    //added these 3 methods 
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
    }

    func applicationWillResignActive(_ application: UIApplication) {
        FBSDKAppEvents.activateApp()
    }

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

    func applicationDidEnterBackground(_ application: UIApplication) {

    }

    func applicationWillEnterForeground(_ application: UIApplication) {

    }

    func applicationDidBecomeActive(_ application: UIApplication) {

    }

    func applicationWillTerminate(_ application: UIApplication) {

    }
