Ios 使用Swift登录Facebook后加载另一个ViewController

在使用swift成功登录Facebook后，我正在尝试加载另一个视图控制器。我一直在关注这篇博文：

我配置了一个名为“redirectAfterLogin”的segue，并尝试使用performsgueWithIdentifier

下面可以看到我的ViewController.swift和AppDelegate.swift文件。不知怎的，我错过了一些东西。有什么建议吗

ViewController.swift

AppDelegate.swift

这是我登录模拟器后的输出：

2016-02-11 14:43:49.712 TMR-Prototype1[22260:3512428]-canOpenURL:URL失败：“fbauth2:/”-错误：“（空）”

2016-02-11 14:43:49.717 TMR-Prototype1[22260:3512428]-canOpenURL:URL失败：“fbauth2:/”-错误：“（空）”

这是截图。它卡在第一个viewcontroller上：

我还将我的Info.plist文件编辑为：

您应该将

fbsdkloginbuttonelegate

实现到您的

ViewController

，并包括委派方法

class ViewController: UIViewController, FBSDKLoginButtonDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        let loginButton = FBSDKLoginButton()
        loginButton.center = view.center
        loginButton.delegate = self // Remember to set the delegate of the loginButton
        view.addSubview(loginButton)
    }

    func loginButton(loginButton: FBSDKLoginButton!, didCompleteWithResult result: FBSDKLoginManagerLoginResult!, error: NSError!) {
        /* 
           Check for successful login and act accordingly.
           Perform your segue to another UIViewController here.
        */
    }

    func loginButtonDidLogOut(loginButton: FBSDKLoginButton!) {
        // Actions for when the user logged out goes here
    }
}

我好像忘了设置登录按钮的委托。谢谢，我好像忘了设置登录按钮的委托。谢谢
