Facebook登录不能在swift中工作

我试图在我的应用中实现Facebook登录，但是当我尝试登录时，它会转到Facebook应用并返回到我的游戏，但登录按钮不会退出，如果我尝试获取访问令牌，授予的权限或拒绝的权限等任何信息。这是我的代码有：Facebook登录不能在swift中工作

import Foundation 
class IntroScene: SKScene, FBSDKLoginButtonDelegate { 
let loginButton: FBSDKLoginButton = { 
    let button = FBSDKLoginButton() 
    button.readPermissions = ["email"] 
    return button 
}() 

override func didMove(to view: SKView) { 
    self.backgroundColor = UIColor.black 

    view.addSubview(loginButton) 
    loginButton.center = (self.view?.center)! 
    loginButton.delegate = self 
} 

func loginButtonDidLogOut(_ loginButton: FBSDKLoginButton!) { 

} 

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

func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: Error!) { 
    if(error == nil) 
    { 
     print("login complete") 
     //print(FBSDKAccessToken.current()) -> crashes because its nil 
     //print(result.grantedPermissions) -> crashes its nil 
    } 
    else{ 
     print(error.localizedDescription) 
    } 
} 
}

我的info.plist看起来像以下：

你使用哪个版本迅速？ –

不够好给你一个完整的解决方案，所以这就是它。试试看，https://edbinx.com/apple/ios/use-facebook-fbsdk-swift-cocoapods-ios-9-13369.html – Fennec

即时通讯使用Swift 3 @HimanshuMoradiya – toiavalle

多亏了这个帖子：FB Login using Swift 3 not returning any values and not get back the user to the App after successful login 我发现这个问题。还有一个功能应该添加到App Delegate中。这里是我如何得到Facebook登录工作

下载SDK并添加到项目
根据Facebook的网站设置的info.plist

在应用程序的委托补充说：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 
// Override point for customization after application launch. 
FIRApp.configure() 
FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions) 

return true 
} 

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) 
}

我在显示按钮（也可以在视图控制器中）：（

class IntroScene: SKScene, FBSDKLoginButtonDelegate { 
    override func didMove(to view: SKView) { 
     self.backgroundColor = UIColor.black 
     let loginButton = FBSDKLoginButton() 
     loginButton.center = (self.view?.center)! 
     self.view?.addSubview(loginButton) 
     loginButton.frame = CGRect(x: 0, y: 0, width: 360, height: 60) // makes it bigger 
     loginButton.center = CGPoint(x: self.frame.midX, y: self.frame.midY + 90) 
     loginButton.delegate = self 
     loginButton.readPermissions = ["public_profile", "email"] 
     if let _ = FBSDKAccessToken.current(){ 
      //already logged in 
      fetchProfile() 
     } 
    } 
    func fetchProfile() { 
    let parameters = ["fields": "first_name, email, last_name, picture"] 

    FBSDKGraphRequest(graphPath: "me", parameters: parameters).start(completionHandler: { (connection, user, requestError) -> Void in 

     if requestError != nil { 
      print("----------ERROR-----------") 
      print(requestError) 
      return 
     } 
     let userData = user as! NSDictionary 
     let email = userData["email"] as? String 
     let firstName = userData["first_name"] as? String 
     let lastName = userData["last_name"] as? String 
     var pictureUrl = "" 
     if let picture = userData["picture"] as? NSDictionary, let data = picture["data"] as? NSDictionary, let url = data["url"] as? String { 
      pictureUrl = url 
      print(pictureUrl) 
     } 
    }) 
    } 

}

将这个代码在你AppDelegate.swift

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { 
     return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions) 
} 



func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool { 
     return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation) 
}

检查Facebook Facebook按钮中的FacebookAccessToken点击ViewController。

if FBSDKAccessToken.currentAccessToken() != nil { 
      FBSDKLoginManager().logOut() 
      return 
} 

let login:FBSDKLoginManager = FBSDKLoginManager() 
login.logInWithReadPermissions(["email"], handler: { (result:FBSDKLoginManagerLoginResult!, error:NSError!) -> Void in 
    if(error != nil){ 
      FBSDKLoginManager().logOut() 
    }else if(result.isCancelled){ 
      FBSDKLoginManager().logOut() 
    }else{ 
       //Handle login success 
      self.returnUserData() 
     } 
})

获取FacebookData的响应。

func returnUserData() 
{ 
    let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "email"]) 
    graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in 
     if ((error) != nil) 
     { 
      // Process error 
      print("Error: \(error)") 
     } 
     else 
     { 
      print(result) 

     } 
    }) 
}

我已经拥有App Delegate代码（抱歉，我忘记了包含在问题中）。对于中间部分，我应该把代码放在哪里？我需要一个视图控制器还是可以使用SKScene Im？我应该在哪里放？ viewDidLoad中？当我尝试添加它时，也出现此错误无法将类型'（FBSDKLoginManagerLoginResult !, NSError！） - > Void'的值转换为期望的参数类型'FBSDKLoginManagerRequestTokenHandler！' – toiavalle

@toiavalle我不使用swift 3.0我使用的是swift 2.0，所以他们可能从你的身边，然后将此代码转换为swift 3.0中的正常工作。谢谢。 –
