Facebook登录Swift iOS 10-无效

Question

我正在运行最新版本的XCode和Swift。 我正在尝试实施Facebook登录； 但是，我一直遇到持续的错误。

首先我得到这个：

-canOpenURL: failed for URL: "fbauth2:/" - error: "The operation couldn’t be completed. (OSStatus error -10814.)"

我实施了此处列出的解决方案， 但仍然没有运气 。 如何在iOS 10上使用Facebook iOS SDK

我试过仔细检查“钥匙串访问”，重新安装FacebookSDK，并以各种不同的方式实现它，例如： http : //ashishkakkad.com/2015/05/facebook-login-swift-language-ios，但我似乎无法避开这个。

这是我的登录结果： Optional(<FBSDKLoginManagerLoginResult: 0x170251550>

不确定是否正确。 虽然我没有网络中断并且我的wifi已完全连接，但我也收到此错误。 Could not successfully update network info during initialization.

    @IBAction func fbLoginButtonPressed(_ sender: AnyObject) {
        let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
        fbLoginManager.logIn(withReadPermissions: ["email"], from: self) { (result, error) in
            print("Here is the result", result)
            print("Here is the error" , error)

            if (error == nil){
                print("the error is nil")
                let fbloginresult : FBSDKLoginManagerLoginResult = result!
                //commenting if statement out temporarily for debugging purposes

//                if(fbloginresult.grantedPermissions.contains("email"))
//                {
                print("email is contained and printing result")
                self.getFBUserData()
                fbLoginManager.logOut()
//                }
            }
        }
    }

    func getFBUserData(){
        if((FBSDKAccessToken.current()) != nil){
            FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, picture.type(large), email"]).start(completionHandler: { (connection, result, error) -> Void in

                print("inside get FB user data")
                if (error == nil){
                    self.dict = result as! [String : AnyObject]
                    print(result!)
                    print(self.dict)
                }
            })
        }
    }

为什么会发生这种情况，如何解决？

Answer 1

您的代码很完美，但是您必须启用Facebook登录的钥匙串访问权限

那会解决你的问题

Answer 2

我意识到问题出在应用程序委托https://gist.github.com/codegefluester/f797dd723e93e545b855525a4b9ab057

import UIKit
import CoreData

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    public func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
        // Override point for customization after application launch.

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

    public func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {

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

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