使用 Swift 3 的 FB 登录不返回任何值，并且在成功登录后不让用户返回应用程序

我在用着iOS 10 Swift 3集成FB Login。我已遵循以下所有步骤Facebook文档。现在的问题是，成功登录后，它不会返回任何值，也不会让用户返回应用程序。

注意：同样适用于Swift 2.

您好，我向 facebook 开发人员支持提出了这个问题，问题是我没有为 iOS10 实现正确的委托方法。你可以找到正确的委托实现here 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)
}
}
