如何在swift 2.0中使用facebook登錄

我使用facebook應用程序創建了一個登錄。起初，我去我的個人資料，我創建了應用程序ID，我添加了捆綁標識符。所以，只要我複製並過去到在facebook上創建的具有應用ID和分組標識符的info.plist。然後我添加了FBSDKCoreKit.framework和FBSDKLoginKit.framework。我添加了一些代碼。問題是，Facebook登錄成功。但是，當我按下按鈕時，錯誤被打印出來，並且FBSDKLoginButtonDelegate函數沒有被調用。我的系統是Lenovo B460e上的Hackintosh Yosemite。請參閱代碼中的單行註釋。提前致謝。如何在swift 2.0中使用facebook登錄

錯誤：

2016年8月17日19：51：40.736的Facebook [925：34154] -canOpenURL：失敗URL：「fbauth2：/」 - 錯誤：「（空）」 2016年8月17日19：51：40.808的Facebook [925：34154] -canOpenURL：失敗的URL：「fbauth2：/」 - 錯誤：「（空）」

代碼，我嘗試

info.plist

這是我AppDelegate.swift

import UIKit 

@UIApplicationMain 
class AppDelegate: UIResponder, UIApplicationDelegate { 

var window: UIWindow? 


func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { 

    FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions) 
    return true 
} 

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

} 

func applicationDidEnterBackground(application: UIApplication) { 

} 

func applicationWillEnterForeground(application: UIApplication) { 
} 

func applicationDidBecomeActive(application: UIApplication) { 

    FBSDKAppEvents.activateApp() 
} 

func applicationWillTerminate(application: UIApplication) { 

} 


}

這是我的看法Controller.swift

import UIKit 

class ViewController: UIViewController,FBSDKLoginButtonDelegate { 

override func viewDidLoad() { 
    super.viewDidLoad() 

    let loginButton: FBSDKLoginButton = FBSDKLoginButton() 
    loginButton.center = self.view.center 
    self.view!.addSubview(loginButton) 

    if (FBSDKAccessToken.currentAccessToken() != nil) { 

     print("Hello World!") 
     self.fetchProfile() //This function called and name,Id printed when the application opens initially that already logged in. 
    } 

} 

func fetchProfile() 
{ 
    print("Profile Fetched success fully") 

    let req = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"id,name"], tokenString: "accessToken.tokenString", version: nil, HTTPMethod: "GET") 
    req.startWithCompletionHandler({ (connection, result, error : NSError!) -> Void in 
     if(error == nil) 
     { 
      print("result \(result)") 
     } 
     else 
     { 
      print("error \(error)") 
     } 
    }) 

} 


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

func loginButton(loginButton: FBSDKLoginButton!, didCompleteWithResult result: FBSDKLoginManagerLoginResult!, error: NSError!) { 

    print("Hola") //This function not called when got name and ID 
} 

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

    print("Hello") //This function not called when i log in 
    return true 
} 
func loginButtonDidLogOut(loginButton: FBSDKLoginButton!) { 

    print("Ni Hao") //This function not called when i log out 

}
