ios - 与 FacebookSDK 集成时获取个人资料信息

Question

我一直在将 FacebookSDK 与堆栈溢出和一些教程集成在一起，但它对我来说工作不正常。我无法获取配置文件数据。这个方法甚至没有被调用。只出现“完成登录”。登录过程正在运行，但注销选项从未按应有的方式出现在按钮上。感谢您提供任何提示。

 import Foundation
 import UIKit
 import FBSDKLoginKit
 import FBSDKCoreKit



 class mainView: UIViewController, FBSDKLoginButtonDelegate {

@IBOutlet weak var navigationBar: UINavigationBar!
@IBOutlet weak var mainImage: UIImageView!
@IBOutlet weak var getRecipeBtn: UIButton!
@IBOutlet weak var addImageBtn: UIButton!

let loginButton: FBSDKLoginButton = {
    let button = FBSDKLoginButton()
    button.readPermissions = ["email"]
    return button
}()

override func viewDidLoad() {
     super.viewDidLoad()

    view.addSubview(loginButton)
    loginButton.center = view.center
    loginButton.delegate = self

    if let token = FBSDKAccessToken.current() {
        fetchProfile()
    }
}

func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: Error!) {
    print("completed login")
}

func loginButtonWillLogin(_ loginButton: FBSDKLoginButton!) -> Bool {
    return true
}

func loginButtonDidLogOut(_ loginButton: FBSDKLoginButton!) {

}


func fetchProfile() {
    print("fetch profile")

    FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "email, first_name, last_name, id"]).start(completionHandler:  { (connection, result, error) in guard

        let result = result as? NSDictionary,
        let email = result["email"] as? String,
        let user_name = result["fist_name"] as? String,
        let user_id = result["id"] as? String

            else {
                return
        }
        print(email)


       })
   }
}

这是我的控制台日志部分:(我已将 fbauth 添加到 info.plist。)

RecipeMaster[19428:630625] -canOpenURL:URL 失败:“fbauth2:/”- 错误:“操作无法完成。(OSStatus 错误 -10814。)” 完成登录

您可能必须转到 Targets->Capabilities 并启用钥匙串(keychain)共享(它可以为您的应用程序访问钥匙串(keychain))，according to this answer.
