  如果您正确设置框架并遵循Parse的Facebook设置指南（https://parse.com/docs/ios/guide#users-facebook-users）的步骤，此代码将起作用 . 确保您的语法与我的函数相同，并尝试删除下面未包含的任何不必要的代码 .

  AppDelegate.swift

  import UIKit
  import CoreData
  import Parse
  
  @UIApplicationMain
  class AppDelegate: UIResponder, UIApplicationDelegate {
  
  var window: UIWindow?
  
  func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
  
      //X's replace my actual Parse information
  
      Parse.setApplicationId("XXXXXXXXXXXXXXXXXXXXXX", clientKey: "XXXXXXXXXXXXXXXXXXXXXX")
      PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)
  
      PFFacebookUtils.initializeFacebookWithApplicationLaunchOptions(launchOptions)
  
      return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
  
  }
  
  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 throttle down OpenGL ES frame rates. 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 inactive state; here you can undo many of the changes made on entering the background.
  }
  
  func applicationDidBecomeActive(application: UIApplication) {
  
      FBSDKAppEvents.activateApp()
  }
  
  /*
  func application(application: UIApplication, url: NSURL, sourceApplication: NSString, annotation: AnyObject) -> Bool {
  
      return FBSDKApplicationDelegate.sharedInstance().application(
          application,
          openURL: url,
          sourceApplication: sourceApplication as String,
          annotation: annotation)
  
  }*/
  
  func application(application: UIApplication,
      openURL url: NSURL,
      sourceApplication: String?,
      annotation: AnyObject?) -> Bool {
          return FBSDKApplicationDelegate.sharedInstance().application(application,
              openURL: url,
              sourceApplication: sourceApplication,
              annotation: annotation)
  }
  
  func applicationWillTerminate(application: UIApplication) {
      // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
      // Saves changes in the application's managed object context before the application terminates.
      self.saveContext()
  }
  

  ViewController.swift

  import UIKit
  
  class ViewController: UIViewController {
  
  override func viewDidLoad() {
      super.viewDidLoad()
      // Do any additional setup after loading the view, typically from a nib.
  }
  
  override func didReceiveMemoryWarning() {
      super.didReceiveMemoryWarning()
      // Dispose of any resources that can be recreated.
  }
  
  let permissions = [ "email","user_birthday", "public_profile", "user_friends"]
  
  @IBAction func loginButtonPressed(sender: AnyObject) {
      PFFacebookUtils.logInInBackgroundWithReadPermissions(permissions) {
          (user: PFUser?, error: NSError?) -> Void in
          if let user = user {
              if user.isNew {
                  println("User signed up and logged in through Facebook!")
              } else {
                  println("User logged in through Facebook!")
              }
          } else {
              println("Uh oh. The user cancelled the Facebook login.")
          }
      }
  }
  
  }
  

  @IBAction是一个简单的UIButton我放在我的Main.storyboard中的空白视图控制器的中心

  Objective-C桥接 Headers ：

  #import <FBSDKCoreKit/FBSDKCoreKit.h>
  #import <ParseFacebookUtilsV4/PFFacebookUtils.h>
  #import <Parse/Parse.h>
  

  希望这能解决你的问题！
