facebook swift sdk 0.2.0 swift 3.1登录页面保持打开状态

我正在使用;

  • swift sdk 0.2.0和

  • swift 3.1

所以，在我的 viewcontroller （ initial.swift ）我

import UIKit
import FacebookCore
import FacebookLogin
...
override func viewDidLoad() {
if let accessToken = AccessToken.current {
   print("User is already logged in")
   ...
}
else {
   let loginButton = LoginButton(readPermissions: [ .publicProfile, .email ])
   loginButton.center = view.center

   //AFTER ACTION
   let loginManager = LoginManager()
   loginManager.logIn([ .publicProfile, .email ], viewController: self)
        { loginResult in
            switch loginResult {
            case .failed(let error):
                print(error)
                break
            case .cancelled:
                print("User cancelled login.")
            case .success(let grantedPermissions, let declinedPermissions, let accessToken):
                print("Logged in!")
            }
        }
}

登录按钮按预期显示，但在权限页面后，白页保持打开状态，当我单击"done"手动应用程序认为用户取消登录时 .
有类似的线程暗示缺少app delegate 函数（34734885），但我想这是 FBSDKCoreKit 和 FBSDKLoginKit 的解决方案，而不是新的facebook swift sdk . 我想，再一次 . 有什么建议吗？

编辑
我也试过这个;

let myLoginButton = UIButton()
myLoginButton.backgroundColor = UIColor.darkGray
myLoginButton.frame = CGRect(0, 0, 180, 40);
myLoginButton.center = view.center;
myLoginButton.setTitle("My Login Button", for: UIControlState.normal)
// Add the button to the view
view.addSubview(myLoginButton)
// Handle clicks on the button
myLoginButton.addTarget(self, action: #selector(self.FBloginButtonClicked), for: UIControlEvents.touchUpInside)


@objc func FBloginButtonClicked() {  
    //AFTER ACTION
    let loginManager = LoginManager()
    loginManager.logIn([ .publicProfile, .email ], viewController: self)
    { loginResult in
        switch loginResult {
        case .failed(let error):
            print(error)
            break
        case .cancelled:
            print("User cancelled login.")
        case .success(let grantedPermissions, let declinedPermissions, let accessToken):
            print("Logged in!")
        }
    }
}

    据我所知你做了相应的事情facebook guide?

    包括这部分：

    // Handle clicks on the button
  myLoginButton.addTarget(self, action: @selector(self.loginButtonClicked) forControlEvents: .TouchUpInside)

    和

    // Once the button is clicked, show the login dialog
@objc func loginButtonClicked() {
  let loginManager = LoginManager()
  ...
  }

    根据你的问题，你似乎在appdelegate中写了一个方法 . 成功登录后，这将返回到您的应用程序 .

    import FacebookCore // (FBSDKCore's alternative for swift)

func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
    let isFBOpenUrl = SDKApplicationDelegate.shared.application(application, open: url, sourceApplication: sourceApplication, annotation: annotation)

    if isFBOpenUrl { return true }
    return false
}

    SWIFT 4:

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

    希望这件事能对你有所帮助 .
