为什么IOS13无法使用Facebook登录？

Question

我单击Facebook按钮，但是在iOS 13上没有响应，但是在iOS 12.x上它可以正常工作。我该怎么办？

我正在使用：1）pod'FBSDKCoreKit'，'〜> 5.13.1'2）pod'FBSDKLoginKit'，'〜> 5.13.1'3）pod'FacebookCore'4）pod'FacebookLogin'5）pod'FacebookShare'

Answer 1

您的开放式url方法中的appdelegate无法使用，因为ios13发生了更改

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any]) -> Bool {
  return 
}    

您必须比添加此方法的SceneDelegate.swift文件更新最新的xcode。请尝试。

func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
      guard let url = URLContexts.first?.url else {
          return
      }
      let _ = ApplicationDelegate.shared.application(
          UIApplication.shared,
          open: url,
          sourceApplication: nil,
          annotation: [UIApplication.OpenURLOptionsKey.annotation])
  }

设置info.plist网址类型

//create a function for present root view controller in AppDelegate create var window: UIWindow? 

var appDelegateShared: AppDelegate {
    return UIApplication.shared.delegate as? AppDelegate ?? AppDelegate()
}

create a class for Facebook login
    class WFacebookManager: NSObject {
        typealias FBCallback = (Bool, Any?) -> Void
        var handler: FBCallback?
        static let shared: WFacebookManager = WFacebookManager()
        public func loginWithFacebook(completion: @escaping FBCallback ) {
            handler = completion
            let fbLoginManager: LoginManager = LoginManager()
            fbLoginManager.logOut()
            let presentView = appDelegateShared.window?.rootViewController!
            fbLoginManager.logIn(permissions: ["public_profile", "email"], from: presentView) { (result, error) -> Void in
                if error == nil {
                    if (result?.isCancelled)! {
                        self.handler?(false, nil)
                        return
                    } else if AccessToken.current != nil {
                        let values = "id, name, first_name, last_name, picture.type(large), email"
                        let request = GraphRequest(graphPath: "me", parameters: ["fields": values])
                        request.start(completionHandler: { (_, result, error) in
                            self.handler?(error == nil, result)
                        })
                    }
                } else {
                    self.handler?(false, nil)
                }
            }
        }
    }
    // on your action call function then get login data
    @IBAction func loginWithFacebook(_ sender: Any) {
            WFacebookManager.shared.loginWithFacebook { (success, data) in
                if let data = data as? [String: Any], success {
                    print (data)
                }
            }
        }
