错误您必须初始化PFFVideosUtils

Question

当我在我的应用程序中调用以下Objective C代码时，出现异常。

[PFFacebookUtils logInInBackgroundWithReadPermissions:permissions block:^(PFUser *user, NSError *error) { 
    if (!user) { 
     NSLog(@"Uh oh. The user cancelled the Facebook login."); 
     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Login Failed" 
                 message:@"The user cancelled the Facebook login." 
                 delegate:self 
               cancelButtonTitle:@"OK" 
               otherButtonTitles:nil]; 
     [alert show]; 
    } else if (user.isNew) { 
     NSLog(@"User signed up and logged in through Facebook!"); 
     [self performSegueWithIdentifier:@"logInSegue" sender:sender]; 
    } else { 
     NSLog(@"User logged in through Facebook!"); 
     [self performSegueWithIdentifier:@"logInSegue" sender:sender]; 
    } 
}]; 

终止应用程序由于未捕获的异常“NSInternalInconsistencyException”，理由是：“你必须要在通话初始化PFFacebookUtils + initializeFacebookWithApplicationLaunchOptions”

下面是写在斯威夫特和我的AppDelegate代码我不太清楚如何初始化它在Swift错误中所说的内容吗？我正在使用最新版本的Parse，并且在我的PodFile中，我有以下“ParseFacebookUtilsV4”窗格？任何想法，请问如何解决这个问题？

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool { 

    // Enable storing and querying data from Local Datastore. 
    // Remove this line if you don't want to use Local Datastore features or want to use cachePolicy. 
    Parse.enableLocalDatastore() 

    Parse.setApplicationId(appID, clientKey: clientKey) 
    PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions) 

    let granted: Bool = AppDelegate.IsNotificationPermissionGranted() 
    if (granted) { 
     AppDelegate.registerNotification() 
    } 

    //code block from starter project 
    PFUser.enableAutomaticUser() 

    let defaultACL = PFACL(); 
    // If you would like all objects to be private by default, remove this line. 
    //defaultACL.setPublicReadAccess(true) 

    PFACL.setDefaultACL(defaultACL, withAccessForCurrentUser:true) 

    if application.applicationState != UIApplicationState.Background { 
     // Track an app open here if we launch with a push, unless 
     // "content_available" was used to trigger a background push (introduced in iOS 7). 
     // In that case, we skip tracking here to avoid double counting the app-open. 

     let preBackgroundPush = !application.respondsToSelector("backgroundRefreshStatus") 
     let oldPushHandlerOnly = !self.respondsToSelector("application:didReceiveRemoteNotification:fetchCompletionHandler:") 
     var noPushPayload = false; 
     if let options = launchOptions { 
      noPushPayload = options[UIApplicationLaunchOptionsRemoteNotificationKey] != nil; 
     } 
     if (preBackgroundPush || oldPushHandlerOnly || noPushPayload) { 
      PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions) 
     } 
    } 

    return true 
}

添加以下代码AppDelegate类的didFinishLaunchingWithOptions方法

PFFacebookUtils.initializeFacebookWithApplicationLaunchOptions(launchOptions) 

请注意，您可能需要先导入ParseFacebookUtilsV4。
