Facebook Login Button Terminierung in xcode 9

Question

Ich benutze Xcode 9 und setze den Compiler auf Swift 3.2 Ich habe Facebook Login mit Cocoapods installiert und alles kompiliert ohne Fehler, aber wenn ich es im Simulator starte, klicke ich auf den Login Button stürzt mit nur dieses in der Konsole ausgegeben:

libC++ abi.dylib: mit Ausnahme des Typs uncaught NSException Abschluss (LLDB)

und dies ist mein ViewController.swift:

import UIKit 
import FBSDKLoginKit 
import FacebookLogin 

class ViewController: UIViewController { 

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

Und das ist mein AppDelegate.swift

import UIKit 
import FBSDKCoreKit 

@UIApplicationMain 
class AppDelegate: UIResponder, UIApplicationDelegate { 

var window: UIWindow? 


func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 
    // Override point for customization after application launch. 
    FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions) 
    return true 
} 

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { 
    let handled = FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: options [UIApplicationOpenURLOptionsKey.sourceApplication] as! String!, annotation: options[UIApplicationOpenURLOptionsKey.annotation]) 
    return handled 
} 

func applicationWillResignActive(_ application: UIApplication) { 
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state. 
    // Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game. 
} 

func applicationDidEnterBackground(_ application: UIApplication) { 
    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later. 
    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits. 
} 

func applicationWillEnterForeground(_ application: UIApplication) { 
    // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background. 
} 

func applicationDidBecomeActive(_ application: UIApplication) { 
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface. 
} 

func applicationWillTerminate(_ application: UIApplication) { 
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:. 
}

In Ihrem AppDelegate, didFinishLaunchingWithOptions, haben Sie die boolean vom sharedIstance.application(....) zurück zurückzukehren:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 
    let bool = FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions) 
    FBSDKAppEvents.activateApp() 
    return bool 
} 

Nach Überprüfen Sie Ihre Info.plist, die Sie haben sollten etwas wie das. FacebookAppID und FacebookDisplayName sind erforderlich:
