Facebook for swift 4.2 执行错误

Question

您好，我正在做一个需要 Facebook 登录按钮才能让我们的用户使用 Facebook 帐户登录的项目。但问题是我收到错误。文档似乎很旧，而且无论如何都不起作用。 Here 用于 swift.

我的项目有 swift 4.2。在我的 pod 文件中，我使用了以下依赖项

pod 'FacebookCore' 
pod 'FacebookLogin'

在我的 AppDelegate 中，以下是我的代码

import FacebookCore

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
  SDKApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
  return true
}

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

我收到以下错误。不管我构建我的项目多少次，清理它多少次

Error: Use of unresolved identifier 'SDKApplicationDelegate'

请告诉我这里有什么问题？我必须在这里做什么以及我缺少什么。如果 swift 有什么好的教程请分享给我 link

谢谢

最近发现一个项目实现FB登录。开始了

在 Podfile 中 pod 'FBSDKLoginKit'

在 AppDelegate 中

import UIKit
import FBSDKCoreKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        ApplicationDelegate
            .shared
            .application(application,
                         didFinishLaunchingWithOptions: launchOptions)
        ...
        return true
    }

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

            return ApplicationDelegate.shared.application(app, open: url, options: options)
    }
}

测试 https://developers.facebook.com/docs/swift/implement-the-sdk

播客文件：

  pod 'FacebookCore'
  pod 'FacebookLogin'
  pod 'FacebookShare'

AppDelegate:

import UIKit
import FacebookCore

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        ...

        ApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
        return true
    }

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

看来他们在文档中犯了一个错误，SDKApplicationDelegate 必须重命名 ApplicationDelegate。
