ios - iOS 的 Facebook 登录错误 : The operation couldn’t be completed.(com.facebook.sdk.core 错误 3.)

Question

我收到错误代码:

The operation couldn’t be completed. (com.facebook.sdk.core error 3.)

用于在我的应用程序上登录 facebook，我不确定为什么。这是我的 View Controller 代码:

import FBSDKCoreKit
import FBSDKLoginKit

@IBOutlet weak var facebookLoginButton: FBSDKLoginButton!


  override func viewDidLoad() {
    super.viewDidLoad()

  facebookLoginButton.readPermissions = ["public_profile", "email", "user_friends"]
    facebookLoginButton.delegate = self

  }

  //MARK: Facebook Login

  func loginButton(loginButton: FBSDKLoginButton!, didCompleteWithResult result: FBSDKLoginManagerLoginResult!, error: NSError!) {
    if error == nil {

      print("Login Complete")

      performSegueWithIdentifier("facebookSegue", sender: self)

    } else {

      print(error.localizedDescription)

    }
  }

  func loginButtonDidLogOut(loginButton: FBSDKLoginButton!) {
    print("User logged out")
  }

这是 appDelegate:

import FBSDKCoreKit

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.

      //Facebook login
        return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
    }

  func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {

    //Facebook login
    return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
  }

我认为代码是正确的，但也许我遗漏了什么，感谢任何帮助!

如果您将 Facebook iOS SDK 升级到版本 4.39.0，则存在导致此错误的错误。降级到 4.38.1 将帮助您解决这个问题。请务必同时降级 FBSDKCoreKit 和 FBSDKLoginKit。

pod 'FBSDKCoreKit', '~> 4.38.0'
pod 'FBSDKLoginKit', '~> 4.38.0'

请务必清理构建文件夹并重新构建 SDK。
